Topic:  High Performance Technology And Equipment For Forging The Ingots And Blanks Made Of Titanium Alloys And Other Special Steels And Alloys Using Four Dies In Forging Presses

Two technologies are known for forging the ingots and blanks using four dies. The first, well known one, is based on using the radial forging machines (RFM). The second one, which has emerged relatively recently, uses special four-die forging devices (FDFD) installed in the hydraulic forging presses.

For the last several years a big set of studies for the FDFD forging processes was carried out using the modern finite elements methods (FEM). The meaningful progress was achieved in the new design solutions for FDFDs and in the technologies with application of this device to obtain the forgings with round, square and rectangular cross-sections and also for production of complex-shaped forgings made of titanium and other special steels and alloys. The technologies to produce hollow forgings using FDFDs in the forging presses were also developed.

In 2015 together with Lazorkin V.A, we founded the company “Lazorkin-Engineering, LLC”, where I work to the present day as General Director. In Lazorkin-Engineering, LLC I am responsible for the development of the technologies and equipment for press-forging manufacture.  I am an owner of 17 patents and an author of 11 scientific papers.

Principal Researcher
RIST
Topic:  Friction Stir Welding of Ultra Fine Grained Titanium Plate


In recent years, studies have been made to improve the strength of titanium by refinement of the grain size as means for further enhancing the physical properties. Especially, the coarsening of grains due to fusion welding is a factor that lowers the physical properties of the welded part. Therefore, it is necessary to consider maintaining the fine grain size. FSW(friction stir welding) is a typical process of solid-state welding, and the research is ongoing to expand it to materials such as steel and titanium, including soft materials such as aluminum and copper. Process experiments were conducted to compare the weldability of UFG(ultra-fine grained) titanium and conventional titanium.  As a result, when the UFG titanium was welded by the FSW process, the size of the welds remained the same as 1㎛ of the base metal. The tensile properties of the weld were evaluated to be about 90% of the base metal.

Dr. Sungwook Kim has been working for the Metallic Materials Research Gr. at RIST(Research Institute of the Industrial Science and Technology) in South Korea. His major fields of research focus on welding, surface modifications and additive manufacturing of metallic materials. He is currently interested in welding and additive manufacturing of titanium parts.

Topic:  Tribocorrosion Aspects of Ti-based Biomedical Implants: Current Concerns and New Directions


Ti based Biomedical Implants are commonly used in clinical management and medical practices, to replace or repair malfunctioned or failed body parts or joints. The challenge of a clinician is to have an implant which satisfies the functional requirements of the patients, and it should have minimum side effects on the patient's body. Several clinical reports and studies showed the early failure of such implants and release of the metal ions/particles to the surrounding tissues, which become a serious clinical concern. Such processes are mainly caused by the mechanical movements of the implants coupled with the effect of body environment.  The effect can be the biochemical or electrochemical response of the implant metals to the surrounding solution, which is called as corrosion. Furthermore, the combined effect of such mechanical factors and chemical and electrochemical factors is known as tribocorrosion.    This talk will address the recent progress in the tribocorrosion (sliding/fretting) studies on the Ti biomedical implants, as a function of mechanical, biochemical and biological variables.  Last 10 years, the research from our own lab, on corrosion, tribology and tribocorrosion aspects of biomedical implants will be discussed and summarized.   Surface modification or coatings may increase the surface properties, however, many concerns about its stability. Recent our studies showed that the metal oxide surface modification could enhance the biocompatibility of the metallic implants and accelerate the osteointegration process. Such method of functionalization can overcome material deficiencies while maintaining its bulk material properties. Currently used different coatings, CDC, UNCD, MAO plasma coatings and surface modifications will be included and clinical concerns will be discussed.

Dr. Mathew's major research focus is in the area of simulation of human artificial joints, biomechanics and tribocorrosion of implanted biomaterials used in dentistry and orthopedics.

Topic:  Structure and Mechanical Behaviour of Titanium Based Multi-Layered Materilas Fabricated by Blended Elemental Powder Metallurgy for Anti-Ballistic Applications

Due to the high specific strength of Ti, materials on its base are considered viable alternatives for low-weight armor. However, the feasibility of implementation is questionable when the armor parts are fabricated using traditional and pricy ingot and wrought technology. We suggest a more cost efficient process of producing armor parts using blended elemental powder metallurgy (BEPM) of Ti-base materials.  Multi-layered structures of Ti-6Al-4V (Ti-64) alloy and its metal-matrix composites (MMC) with 5-10% (vol.) of TiC and TiB were fabricated using BEPM of hydrogenated Ti.  Structure of materials were characterized using light optical microscopy, scanning electron microscopy (SEM), electron backscattered diffraction and x-ray microscopy. Mechanical behavior of the layered structures has been evaluated using tensile and 3-point flexural tests. The fracture surface of tested materials was characterized using SEM and the deformation energy was measured based on engineering stress-strain curves obtained on tensile test. We have found that during the sintering of the layered structures of Ti-64 alloy and some MMC layers can shrink at different values causing negative consequences on shape alteration and cracking of relatively large plates. However, shrinkage mismatch between layers of the alloy and its MMC can be effectively mitigated by controlling initial powder particle size and hydrogen content. Using optimized processing parameters, relatively large ML plates were made via BEPM and give superior anti-ballistic performance than similarly sized plates fabricated by traditional ingot and wrought technology.   

Sergey Prikhodko is Associate Adjunct Professor at the department of Materials Science and Engineering, University of California Los Angeles. He is also a Director of Electron Microscopy Core Laboratory at the department. The area of his scientific expertise lays in structure characterization of materials by advanced microscopies and spectroscopies.

Topic:  Socio-economic Impact of Metal Industries and Implications for Titanium


Titanium generates significant socio-economic benefits throughout its entire supply chain, from mining, through to melting and milling, and through its downstream use. But the true extent of titanium’s impact is generally underappreciated. Aside from the direct impact of titanium on job creation, labour income, value addition, research and development, investment, and revenue generation through taxes and contributions, significant indirect effects are often not accounted for. Purchases in local economies, and income effects, typically double or triple the true impact. A better understanding of the true socio-economic footprint of titanium can be a major asset in discussions and negotiations on permitting, licensing, taxes, and royalties, at the community, national, and industry level. Roskill has undertaken a number of socio-economic impact assessments on chromium, nickel and cobalt, and will outline what these might teach us about the titanium market, which could also form the basis for a larger study assessing the full societal role of titanium from a socio-economic perspective.

Topic:  Improvements in Oxidation Resistance: A New Titanium Alloy for Aerospace Applications


Next generation fuel-efficient jet engines are running hotter presenting a structural challenge for the exhaust systems and structures adjacent to the engines. A conventional and affordable titanium alloy with superior oxidation resistance provides significant weight reductions and end item cost savings by eliminating the need for high density material systems such as nickel-based superalloys for service temperatures in between current titanium alloys and nickel, enabling major technology advancements in high temperature aerospace applications. This presentation will provide an overview of Arconic’s patented titanium alloy Arconic-THORTM that addresses the needs of future aerospace systems.

Improvements in temperature capability of titanium alloys in the last 65 years have only been incremental. Ti-6Al-2Sn-4Zr-2Mo (Ti-6242), introduced commercially in 1989, with maximum service temperature capability of 1000°F remains still the state-of-the-art. Balancing alloy formulation and processing to achieve desired performance without compromising producibility and affordability has been a major challenge in the development of high temperature Ti alloys. Current temperature needs in aerospace applications are pushing beyond the available Ti alloys, driving the use of high-density materials and expensive manufacturing solutions for these applications, which increases the end product’s weight and is an underutilization of their capability.

Mr. Crist is currently the Engineering Manager for the Arconic Engineered Structures R&D team based in Niles, OH. Throughout his 29-year career at Arconic (RMI Titanium/RTI International Metals), Mr. Crist has held various process engineering and technical management positions, and has served in his present role since 2010. Mr. Crist’s titanium experience is predominantly in thermo-mechanical processing and characterization of titanium alloys. He manages the team responsible for titanium alloy development, and is also heavily engaged in manufacturing titanium aluminide alloys used in aerospace applications.

Topic:  Feinguss Blank, Our Approach of Know-How and Know-Why for Producing TiAl Applications

The cost reduction of parts and processes is always a big issue for every company. Also environment protection and resource saving is more important than ever. In the past, the investment casting industry satisfied the customer needs with their know-how by casting whatever the customer wanted. Now the customer can come with a problem and gets different casting solutions with the use of the digital twin. This is a simulation loop consisting of material-, casting-, FEM-, and topology- simulation. With this, you can try different part options simultaneous without wasting real resources and reduce the time and costs of development through simulation. Once the part geometry is fixed, you can simulate and optimize a lot of the investment casting process steps and also the steps of the following postprocessing, including all sorts of the machining and assembly process. After this complete digitalization of the value added chain, you have the know-why of the product and your process. With this predictability of the process, you can increase the part quality and process stability. This means a maximum security and stability for the customer through the complete process. The next generation alloys like TiAl require more advanced wax and ceramic materials. By means of using the Blank Digital Twin, we do more and more testing and development in this area. Through this we have a deeper process control & material understanding. With this information, the investment casting industry can raise their know-how. The more testing and development you do, the more relations between the parameters you get. The moment, when you have all your links and relations, you have the necessary know-why of all your processes.

Keith Fleming has over 20 years experience in different capacities from managing defense contractors to, most recently, managing a German investment casting US startup. His passion for customer interaction and business development started in a Western Pennsylvania family owned and operated pizza shop at the age of 16.

Topic:  Analysis of Chip Formation in Machining Nickel Based and Gamma Titanium Alloys

Nickel based alloys and gamma titanium aluminides are well studied advanced materials applied in aerospace engines and turbines. It is known that tool wear is increased due to the high cutting temperatures and cutting forces and in milling due to the intermittent contact and the discontinuous cut. Chip formation is a primary indicator to analyze the surface quality of machined workpieces. Short chips with little segmentation lead to a better workpiece surface. While chip formation and surface quality are discussed in several studies in machining nickel based alloys, only a few investigations have been made in machining brittle hard gamma titanium aluminides. In previous literature, it can be seen that micron-sized chips are produced inside the shear zone during the machining process. In the following paper, such chip formation will be examined by using a high speed camera while turning the above mentioned materials.

I was born in Dortmund, Germany in 1987. While I was studying industrial engineering at the TU Dortmund with the special topic of mechanical engineering, I decided to specify in machining technology of difficult-to-cut materials like nickel based and titanium alloys. My special topic is about the investigation of the machining behavior of nickel based and gamma titanium alloys. At this moment I am one of the scientific member at the TU Wien, so I am writing my PHD thesis about this topic that I've mentioned.

Metalysis: Chapter One When a solid-state electrolysis process was discovered at Cambridge University in 1997, it marked the genesis of a scientific breakthrough known today as The Metalysis Process.  Since Metalysis was established in 2005, the technology has been developed from a promising proof-of-concept to a true industrial process.  The commercial reality of this technology is known as the Company's Generation plant is up and running in the UK. What began as a lightbulb moment of scientific curiosity has been steadily grown into an economically and environmentally compelling modular production method, ready to deliver 100s-1000s of tonnes of high value advanced alloy combinations. The Titanium family's represents an important avenue for launch materials. While Metalysis process is simple in concept, in reality it is a new feat of electrochemical engineering at scale. In simple terms, electrons are used to remove oxygen from a range of metal oxides to generate metals, alloys or intermetallics; products which present structural, thermal, electronic, magnetic and chemical properties of huge demand to a wide range of end-user applications including the industries of aerospace, automotive and advanced manufacturing. This presentation will explain what it really takes to develop a promising laboratory experiment into a commercial reality. It will explain our latest technology and products, including but not limited to Titanium, and offer insights ahead of the next chapter in Metalysis' story.

Topic: Titanium and Tricor Metals go to the SUN
 
 


Since 2011, Tricor Metals has been working with Johns Hopkins University – Applied Physics Lab in Laurel, MD to design and built the Truss Structure Assembly (TSA) for the Parker Solar Probe (PSP) program. The final TSA flight unit was fabricated by Tricor in late 2015 and the program has come to fruition with the launch of the PSP spacecraft at 3:31 AM on August 12, 2018.

The initial design proposed by JHU-APL used both Titanium Grade 9 and Grade 5 for the Assembly. However, after discussions between Tricor and JHU-APL, this was quickly changed to using Titanium Grade 5 for all components, due to weight and strength requirements. Weight was so critical that some of the components (the tubing structural supports) also required chemical milling to reduce thickness and weight. The overall dimensions of the Assembly were also very critical and required the use of a sophisticated fixture system and precise welding by Tricor welders.

Throughout the program, which included the fabrication of 2 pre-flight units and the final flight unit, Tricor Metals engineers worked closely with JHU-APL engineers to ensure the on-time delivery of the TSA’s and the overall success of the program. The final flight unit was shipped in August 2015 and underwent rigorous testing before (and during) the assembly of the instrument packages, heat shield and other devices onto the TSA to complete the Parker Solar Probe satellite.

Tricor Metals is proud to have been a small but absolutely critical part of this novel scientific mission in conjunction with Johns Hopkins University – Applied Physics Lab and NASA.

Topic:  Titanium Scrap-More Questions than Answers


It’s an exciting time in the titanium scrap industry.  Record airplane builds are resulting in record amounts of scrap being generated and growing demand for this key raw material. Melters are simultaneously increasing their melting volumes while at the same time attempting to increase the percentage of scrap used to make their products.  Forecasting what’s coming however is more of a challenge than ever as many current unknowns are converging to make the future difficult to predict.   Where is the sponge supply headed?  How will the current master alloy situation affect scrap demand and pricing?  With the boom in U.S. domestic steel production and the corresponding increase in demand for ferro titanium, will scrap demand for ferro-titanium affect the market as it has in previous cycles? Changes in buy to fly ratios, powder and additive manufacturing, and potential changes in where scrap is generated and consumed will all effect scrap availability. Finally, what affect will the current world trade situation have on scrap movement around the globe? Lots to discuss!

Abstract Powder metallurgy as a whole is typically used as a cheaper option to producing metallic components when compared with wrought processing. Traditionally, the disadvantage to powder metallurgy titanium is its lower mechanical properties due to its residual density and coarse microstructures in the as-sintered states. Hydrogen sintering and phase transformation (HSPT) is a blended elemental powder metallurgy process to produce low cost titanium alloy with good mechanical properties. HSPT takes advantage of phase transformations in titanium alloy, particularly Ti-6Al-4V alloy, with existence of hydrogen to simultaneously obtain ultrafine microstructure in as-sintered status. In this study, titanium-6Al-4V produced with HSPT was produced and mechanically tested, to show how these samples could be done without thermal treatments. Following this production of material, these materials underwent simple heat treatments without thermomechanical processing to produce “wrought-like” microstructures (e.g bi-modal and globuralized microstructures) for potentially different applications. Fatigue properties of HSPT processed Ti-6Al-4V with different microstructures were tested and were compared with wrought materials. The results showed that with HSPT as a processing option, a range of different microstructures can be produced for PM Ti-6Al-4V to allow this material to compete with wrought in regards to both tensile and fatigue properties.

Transformation-induced plasticity (TRIP) and toughening has been thoroughly studied in ferrous systems, leading to the success of various TRIP steels. Novel near-α titanium alloys for structural applications with both high strength and fracture toughness are computationally designed using the same concept of TRIP steels. In order to obtain peak transformation toughening effects, the β phase composition is adjusted to have the characteristic Msσ at the crack tip stress state around room temperature. Mechanistic models describing the thermodynamics and kinetics of martensitic transformation in titanium alloys were applied to calculate Msσ (ct). β phase composition evolution of prototype alloy Ti-8111Fe annealed at 865C were experimentally validated. The results show that morphology and size of β phase affect its composition due to capillarity effects. Deformation induced martensitic transformation from β to α” are validated by tensile tests. Ongoing work is experimentally investigating the relationship between β phase stability and uniform ductility/fracture toughness with commercial alloys such as Ti-64. The alloy composition, annealing temperature and cooling rate will then be redesigned to optimize β phase stability and achieve design goals of mechanical properties.

The light-weight metals have many applications in various areas like: aviation, automotive, biomedical and chemical industries in order to boost the fuel economy and reduce the carbon dioxide emission. Among the light-weight metals, Titanium alloy is an ideal candidate due to their excellent properties like: high strength/weight ratio, fraction resistance, corrosion resistance and high operating temperature. However, Titanium alloys, they have a poor machinability because it has low thermal conductivity and really mechanical reactive. To improve the machinability, there are two regular resolutions, they are, firstly, apply the CVD or PVD coatings on carbide inserts which has successful in machining ferrous alloys but do not significantly improve for Titanium alloys. Secondly, the flood cooling is usually applied on the machining process of Ti alloy to provide sufficient cooling. Although the flood cooling improved the surface finish and tool life, the health/environmental concerns and the eventual disposal cost of cutting fluid are known to be the main practical issues in industries. To resolve these issues, minimum quantity lubrication (MQL) was proposed as an ecological machining solution. This study evaluates the performances of dry, MQL and MQL with nanofluid in turning the most common titanium (Ti) alloy, Ti-6Al-4V, in a solution treated and aged (STA) microstructure. In particular, the nanofluid evaluated here is vegetable oil (rapeseed) mixed with a small concentration of exfoliated graphite nanoplatelets (xGnP). The focus of this study is on turning process because it poses a challenging condition to apply oil droplets directly onto the tribological surfaces of a cutting tool due to the continuous engagement of tool and work material. A series of turning experiments was conducted with uncoated carbide inserts while measuring the cutting forces with the dynamometer under various conditions. The inserts are retrieved to measure flank and crater wear using confocal microscopy. This preliminary experimental result shows that the use of MQL and nanofluid is effective in improving the machinability of Ti alloys under turning process.

A Feasibility of Hydrogen Reduction of Titanium Tetrachloride by Inductively Coupled RF Plasma

Presently, while a high-grade titanium sponge can be produced by Kroll process, it performs in the batch nature which needs high energy costs and has a low production yield. Besides, many of the subsequent process steps required to produce titanium metal such as melt processing, mill processing and multiple conditioning steps which makes yield loss and cost of product much higher. Accordingly, if a lot of process steps could be reduced, it would lower the cost of titanium products. Thus, there were many attempts to develop process to produce ingot or powder directly from titanium tetrachloride(TiCl₄). In this study, synthesis of titanium powder via hydrogen reduction of titanium tetrachloride by inductively coupled rf plasma was examined. While TiCl₄ is hard to be reduced by hydrogen thermodynamically, dissociated hydrogen radical which formed from hydrogen gas passing through the plasma can react with TiCl₄ to form HCl and subsequently produce titanium. The RF frequency of generator used in this experiment is 13.56 MHz and input power was varied. The reactor and plasma torch tube was made from quartz to observe the reaction in real-time. The effects of various parameters(RF power, gas flow rate and etc.) on powder size, size distribution and phase composition of the powder were investigated and the characteristics of the powder such as powder size, size distribution, and phases were analyzed with XRD, SEM, EDS and TEM. The hydrogen gas was supplied into reactor in which an Ar-plasma is floated, and then TiCl₄ was injected by Ar carrier gas. When the TiCl₄ fed into the reactor, the plasma had flashed and become more brighter. The produced titanium powder were deposited on the inner-wall of quartz reactor, silicon stopper and titanium rod. Deposited height of titanium powders, after 2 minutes reaction, were 4.004 μm and loosely attached that could be easily removed. However, the powder was identified as amorphous and it is considered that the powder was chilled enough to be amorphous by natural heat losses from the quartz reactor wall. Most of the powders were mainly composed of Ti and the average diameter of powders was 100 nm. The size of the powder and particle agglomeration depended on the flow rate of plasma gas and the length of plasma.

Development of Seismic Retrofits for Reinforced Concrete Bridge Columns Using Titanium Alloy Bars

Most buildings and bridges in service at present were not constructed to modern seismic design standards. As a result, these structures perform poorly during large earthquakes. Many older bridges in the US and around the world are supported on seismically deficient reinforced concrete (RC) columns. The most common deficiencies in these columns are lap-splices located in the plastic hinge region above the footing, insufficient lap-splice length, and inadequate transverse reinforcement which cannot confine the core concrete. These three features result in non-ductile response of the columns and can lead to collapse of the supported structure during an earthquake.

To improve the seismic performance of existing RC bridges, a novel retrofit method was developed, applied to full-scale column specimens with vintage details, and tested in the laboratory. The retrofit uses titanium alloy bars (TiABs) (Ti-6Al-4V) combined with conventional concrete. TiABs provide well-defined material properties, excellent corrosion resistance, and ease of fabrication. Continuous TiABs spirals were used to provide confinement and supplemental longitudinal TiABs were added to provide a load path that is able to resist earthquake induced forces. TiABs were installed using conventional construction industry practices to provide an effective and economical retrofit solution.

The specimens with TiAB retrofits produced seismic performance that was as good as or even better than modern designs. The ability to achieve high seismic performance from older existing structures provides significant savings by minimizing the need for replacement. In addition, the TiAB retrofit solution allows visual inspection of the column after an earthquake to assess damage, a benefit not available from other alternatives.

Integration of Structural Strengthening and Cathodic Protection with Ti-6Al-4V Bars

Reinforced concrete (RC) is the most widely used construction material in the world. RC structures most commonly combine concrete with conventional carbon steel reinforcing bars to resist applied loads and can remain in service over long periods of time. Generally, concrete provides a passive environment that serves to protect the embedded steel from corrosion, but over time and environmental exposure, the steel can corrode. Corrosion decreases the cross sectional area of steel and damages the concrete by producing cracks and spalling. When a RC structure is compromised due to corrosion, the owner must make decisions regarding replacement, restoration, or restricting loads. Due to limited resources, most owners cannot afford to replace their inventory, and thus restoration or retrofitting are commonly used to restore the strength of the deteriorated structure.

Titanium alloy bars (Ti-6Al-4V) (TiABs) have recently been developed to strengthen existing RC structures, both for gravity loads and to resist earthquakes. The TiABs use a surface pattern to allow the bars to be bonded with structural epoxy to the concrete substrate. This application has been shown to increase strength, deformation capacity, and energy dissipation. While at present, TiABs have been applied only considering their contribution to structural performance, this study considers using them as a multi-functional material that uses their attributes for both immediate strengthening and long-term preservation of the embedded carbon steel from further corrosion. To achieve this goal, TiABs are integrated into a cathodic protection system. Impressed Current Cathodic Protection (ICCP) systems in RC structures often use titanium mesh as the second metal for the reduction-oxidation (REDOX) reaction. In an ICCP system, current is applied such that instead of the steel, the titanium corrodes, but at a much slower and less significant rate. By deploying TiABs structurally and in an ICCP system, TiABs can provide immediate and long-term benefits for owners, and this combined attribute cannot be achieved with alternatives. The research is underway and will be completed in June of 2019.

Microstructural Refinement of Ti-6Al-4V During Hydrogen Sintering and Phase Transformation (HSPT)

The hydrogen sintering and phase transformation (HSPT) process is a novel powder metallurgy method for producing Ti alloys, particularly the Ti-6Al-4V alloy, with ultra-fine microstructure in the as-sintered state. The ultra-fine microstructure can be also modified to wrought-like Bimodal or globularized microstructure via simple heat treatments (without hot working). HSPT is a multi-step pressureless sintering process, in which Ti hydride or Ti powder is blended with alloying powders and sintered under a hydrogen atmosphere. After sintering, residual hydrogen is removed by annealing under vacuum or inert gas. In this paper, a pseudo-binary phase diagram of (Ti-6Al-4V)-H was determined by using in situ synchrotron XRD and TGA/DSC techniques. Aided by this phase diagram, the series of phase transformations during the entire HSPT process were investigated. Using experimental techniques, including in situ synchrotron XRD, SEM, EBSD and TEM, the microstructural refinement was found to be the result of: (1) the precipitation of ultra-fine α/α2 homogeneously within coarse β grains during an isothermal hold at intermediate temperatures, and (2) the eutectoid transformation of β→α+δ.

Hydrogen assisted magnesiothermic reduction (HAMR) of TiO2 for an energy efficient production of low cost Ti powder

The development of low cost titanium metal production processes has challenged the Ti research and industrial communities around the world for decades. The strong affinity of titanium to oxygen dictates that it is very difficult to produce low-oxygen Ti metal, including that by direction reduction of TiO2. A hydrogen assisted magnesiothermic reduction (HAMR) process for producing Ti metal powder from TiO2 powder at relatively low temperatures (⩽750 °C) has been developed. The overall approach is based on the thermodynamic tuning of the relative stability of MgO versus that of Ti-O solid solutions by temporarily alloying the system with hydrogen. It is shown that Ti-H-O solid solutions are less stable than their corresponding Ti-O solid solutions, which changes the reaction of Mg with Ti-O from being thermodynamically unfavorable to being favorable. The key steps for producing pure Ti metal powder from TiO2 involve Mg reduction of TiO2 in a hydrogen atmosphere which produces porous TiH2, a heat treatment procedure to consolidate the powder and reduce specific surface area of the powder, and the final step to deoxygenate the powder using Mg in a hydrogen atmosphere to further reduce the oxygen content. This approach can indeed produce Ti metal powder that has high purity, low oxygen, and meets the specifications by ASTM for general purpose Ti sponge, directly from commercial TiO2 or upgrade Ti slag without the high temperature chlorination step. The produced powder is dense and its morphology is close to that of HDH powder. The processing energy of HAMR process has ~75 % reduction compared to the Kroll process. Preliminary sintering of HAMR powder showed that the mechanical properties meet the ASTM standard specification ( ASTM B 348). This is a promising technology that has the potential to drastically alter the Ti market and increase the range of applications for high performance, lightweight Ti parts. Status on the research: Right now HAMR process is under pilot production, all research results to show are in hand.

In this paper, a new deoxygenation process for the Ti powder is presented. With the assistant of H2, the O content in Ti powder could be reduced to be less than 0.1 to 0.2 % after reaction with Mg at 700-800oC for 3-6 hours (with starting O content at 0.3%-1.0%); the final O content was highly depending on the powder morphology and size range. Leaching process was followed to remove the residual MgO and salt. No significant composition or morphology change was found in the powder after this process. As a result, this deoxygenation routing is an efficient way to lower the O content, and therefore, to achieve the goal of recovery high O content Ti powder or scrap.

Pore Characteristics of Synthetic Rutile Produced by Selective Chlorination of Ilmenite

Porous synthetic rutile produced by the chlorination reaction of the ilmenite has been used in the chloride process to produce the titanium tetrachloride. It is known that the porous structure of the synthetic rutile improve the reaction rates of subsequent chlorination reaction. However, there has been no report focusing on the pore characteristics of the synthetic rutile.
In this study, the synthetic rutile was produced by selective chlorination of iron from the ilmenite in the fixed bed. And pore characteristics of the selective chlorination reaction products were determined by BET, porosimeter, and SEM analysis. The characteristics of pores, such as the pore size distribution, porosity, and surface area of the particles were investigated on various reaction conditions. Furthermore, kinetic model of gas-solid reaction was applied to identify the effects of pore characteristics on the chlorination reaction rate.
The pores, derived from the removal of iron oxides, were distributed in each single particle. During the chlorination reaction, the chlorine gas diffused into the pores to reach the reaction interface. As the chlorination reaction progresses, a porous product layer was accumulated around the reaction interface and the unreacted core shrinks in size. However, the pore size was independent of reaction time, while it was increased with the reaction temperature. Both the pore size and reaction temperature affect the rate of chlorine gas diffusion through the product layer. When the reaction temperature was 1023 K, the diffusion coefficient was 0.089 cm2/s at which measured average pore diameter was 53 nm. At 1173 K, the diffusion coefficient at the pore size of 198 nm was 0.302 cm2/s, which is about 3.4 times larger than that of at 1023 K. In addition, the diffusion of reaction gas could be hindered by the complex form of pores, so-called tortuosity. As the reaction temperature increases, the tortuosity factor becomes significantly smaller, thus increasing the effective diffusion coefficient.
