Abstract

The invention relates to a method for the production of titanium alloy particulate materials, in particular the invention relates to a process for producing titanium metal alloys via a Solid State Reduction (SSR) process from Titanium oxide (TiO2) and alloying metal oxides and / or elemental metals. A variety of particulate titanium alloys, such as Ti-6Al-4V, Ti-55Ni,γ -Ti-48Al, α2-Ti3Al, Ti-28Nb, Ti-24Nb-3Al, can be produced by mixing metal oxides and / or elemental metals with calcium hydride (CaH2) and heating to carry out a solid state reduction.

Abstract

The invention relates to a process for the production of metal alloy powders, in particular the invention relates to a process for producing titanium metal alloys from titanium dioxide and aluminium. Optionally the process can also include the use of one or more other oxides (metal or non-metal). The result is at least a Ti-Al alloy powder. If another metal oxide is used the result is a Ti-ternary alloy powder. If SiO2 is used the result is a Ti-Al-Si alloy.
