摘要

The invention relates to energy-saving manufacturing of purified hydrogenated titanium powders or alloying titanium hydride powders, by metallo-thermic reduction of titanium chlorides, including their hydrogenation, vacuum separation of titanium hydride sponge block from magnesium and magnesium chlorides, followed by crushing, grinding, and sintering of said block without need for any hydro-metallurgical treatment of the produced powders. Methods disclosed contain embodiments of processes for manufacturing high purity high-purity powders and their use in manufacturing near-net shape titanium and titanium-alloy articles by sintering titanium hydride and alloyed titanium hydride powders produced from combined hydrogen-magnesium reduction of titanium chlorides, halides and hydrides of other metals. Additional titanium hydride powder introduced with titanium tetrachloride beneficially affects the kinetics of magnesium-thermic reduction due to formation of additionally-emitted atomic hydrogen, which helps to reduce presence of oxides, and so cleans inter-particle interfaces of the product and enhances diffusion between all components of the powder mixture.
