Abstract: The invention relates to the manufacture of titanium hydride powder using continuous or semi-continuous process, and using titanium slag or synthetic rutile as raw materials, while hydrogen, titanium tetrachloride, titanium trichloride, titanium dichloride, and hydrogen chloride are participate as intermediate reaction products. The continuous comprises: (a) reduction of TiCl4 to low titanium chlorides followed by cooling a mixture, (b) separating of residual TiCl4 from solid low chlorides by heating the mixture in argon or vacuum up to 150° C. followed by removing the titanium tetrachloride from the mixture, (c) dissociation of TiCl3 to TiCl2 at 450° C. in vacuum followed by removal of gaseous titanium tetrachloride from the reaction zone, condensation to the liquid, and returning back into the reaction retort, (d) dissociation of TiCl2 in vacuum at 750-850° C. to manufacture fine powder of metallic titanium and titanium tetrachloride, whereby hydrogen heated up to 1000° C.

Abstract: The method for manufacturing high-strength discontinuously-reinforced titanium matrix composite comprises the following steps: (a) preparing a basic powdered blend containing the matrix alloy or titanium powders having a particle size <250 ?m for 95% of the powder and powders, which reinforcing matrix during high-temperature operations, such as blended elemental reinforcing powders, ceramic powders, intermetallic powders, and/or powders of complex carbide- and/or boride particles that are at least partially soluble in the matrix, (b) preparing reinforcing powders by co-attrition, mechanical alloying, or pre-sintering of blended elemental powders with each other and graphite, (c) mixing the basic powdered blend with the Al-V master alloy powder, and co-attrited, mechanically-alloyed powders, and pre-sintered powders in the predetermined ratio to obtain a chemical composition of titanium matrix composite material, (d) compacting the powder mixture at room temperature by any of room temperature consolidation
