The deoxidized powder prepared by applying the previous DOSS process to the HDH powder was used as a comparison group for the deoxidation efficiency of the powder produced through the advanced DOSS process of titanium hydride. The experimental schematic of the comparison group is shown Fig. 1(b).
Titanium Powder Metallurgy: A Review – Part 1
est cost titanium PM process, especially if any secondary compaction step (e.g., HIP) can be avoided[15, 21]. In the process, angular titanium sponge fines (or titanium hy-dride powder) and master alloy composition (generally the 60 Al:40 V variety to produce the Ti-6Al-4V composition) are blended together, cold pressed, and sintered to near full
Advanced Titanium Powder Technologies - …
The HDH process is based on the fact that titanium has a very high affinity for interstitial elements such as oxygen, hydrogen, nitrogen, and carbon. When heated in a hydrogen atmosphere, a stable but brittle titanium hydride (delta phase) is produced through the following reaction: Ti (s) + H2 (g) <──> TiH2 (s) Titanium hydride can be readily crushed, milled, and screened into titanium ...

Hunter process - Wikipedia
The Hunter process was the first industrial process to produce pure ductile metallic titanium.It was invented in 1910 by Matthew A. Hunter, a chemist born in New Zealand who worked in the United States. The process involves reducing titanium tetrachloride (TiCl 4) with sodium (Na) in a batch reactor with an inert atmosphere at a temperature of 1,000°C.
