“…Another important challenge for MIM of Ti is controlling the carbon contamination from the binders. Typically, the carbon pickup can be controlled to less than 0.05 wt-% during the entire MIM process [266]. Therefore, Ti carbide is typically absent from Ti-6Al-4V and CP-Ti produced via MIM, as long as the final carbon concentration is kept below 0.08 wt-%.…”

“…The irregular particle shape of HDH Ti or TiH 2 powder generally results in poor flowability of the powder/binder mixture during injection molding. However, it has been proposed that mixing HDH powder with atomised powder could be an effective approach to balance the cost and rheological factors [266,274].…”

“…As a result of consistent development for more than two decades, many Ti components produced via MIM are commercially available today. Additionally, several comprehensive review papers and book chapters have been published on MIM of Ti in the past decade [262][263][264][265][266].…”

Powder metallurgy (PM) of titanium is a potentially cost-effective alternative to conventional wrought titanium. This article examines both traditional and emerging technologies, including the production of powder, and the sintering, microstructure, and mechanical properties of PM Ti. The production methods of powder are classified into two categories: (1) powder that is produced as the product of extractive metallurgy processes, and (2) powder that is made from Ti sponge, ingot, mill products, or scrap. A new hydrogen-assisted magnesium reduction (HAMR) process is also discussed. The mechanical properties of Ti-6Al-4V produced using various PM processes are analyzed based on their dependence on unique microstructural features, oxygen content, porosity, and grain size. In particular, the fatigue properties of PM Ti-6Al-4V are examined as functions of microstructure. A hydrogen-enabled approach for microstructural engineering that can be used to produce PM Ti with wroughtlike microstructure and properties is also presented.

The conversion of feedstock into a shape involves the application of heat and pressure, and possibly solvents. This chapter discusses the operating principle, advantages, limitations, and applications of such shaping processes, namely additive manufacturing, cold isostatic pressing, die compaction, extrusion, injection molding, slip casting, slurry processes, and tape casting. Information on equipment setup, requirements, and the various factors influencing these processes are described. In addition, the chapter provides information on novel approaches and processing costs applicable to these shaping processes.
