Methods of producing a titanium alloy product

A method for producing a particulate titanium alloy product, comprising:

• preparing a particulate oxide mixture including titanium oxide powder;
• reducing the particulate oxide mixture using a metallic reducing agent under a hydrogen atmosphere at a reduction temperature for a reduction time sufficient to produce a hydrogenated titanium product;
• introducing at least one alloying element to the hydrogenated titanium product to form a composite hydrogenated titanium product, wherein the at least one alloying element powder is at least one of a metal oxide powder, an elemental metal, and a metal hydride, further wherein the metal oxide powder is selected from the group consisting of Al2O3, V2O5, CuO, MnO, V2O3, Fe2O3, Nb2O5, ZrO2, MoO3, MoO2, Cr2O3, SnO2, SiO2, Ta2O, CoO, WO3, NiO, and combinations thereof, wherein the elemental metal is selected from the group consisting of Al, Mo, V, Nb, Ta, Fe, Cr, Mn, Co, Cu, W, Zr, Sn, Ni, Si and combinations thereof;
• and wherein the metal hydride is selected from the group consisting of aluminum hydride, vanadium hydride, niobium hydride, tantalum hydride, zirconium hydride, silicon hydride, and combinations thereof;
• heat treating the composite hydrogenated titanium product under a hydrogen atmosphere and a heat treating temperature to reduce pore size and specific surface area to form a heat treated hydrogenated titanium alloy product;
• deoxygenating the heat treated hydrogenated titanium alloy product to reduce residual oxygen to less than 0.3 wt % to form a deoxygenated hydrogenated titanium product;
• and
• optionally dehydrogenating the deoxygenated hydrogenated titanium product to form the titanium alloy product, wherein the deoxygenated hydrogenated titanium product and the titanium alloy product are a particulate.

A method for producing a particulate titanium alloy product, comprising:

• preparing a composite particulate oxide mixture including titanium oxide powder and at least one alloying element powder;
• co-reducing the composite particulate oxide mixture using a metallic reducing agent under a hydrogen atmosphere at a reduction temperature for a reduction time sufficient to produce a hydrogenated titanium alloy product, wherein the co-reduction is performed by heating to the reducing temperature under an inert gas and then introducing the hydrogen atmosphere within about 10% of reaching the reducing temperature;
• heat treating the hydrogenated titanium alloy product under a hydrogen atmosphere and a heat treating temperature to reduce pore size and specific surface area to form a heat treated hydrogenated titanium product;
• deoxygenating the heat treated hydrogenated titanium product to reduce residual oxygen to less than 0.3 wt % to form a deoxygenated hydrogenated titanium product;
• and
• optionally dehydrogenating the deoxygenated hydrogenated titanium product to form the titanium alloy product, wherein the deoxygenated hydrogenated titanium product and the titanium alloy product are a particulate.

• and
• optionally dehydrogenating the deoxygenated hydrogenated titanium product to form the titanium alloy product, wherein the deoxygenated hydrogenated titanium product and the titanium alloy product are a particulate.
