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.

Abstract: A method of separating components from a metal based composite, the method including the steps of increasing the size of a component to be separated and separating the increased sized component from the other components of the composite.

Abstract: A titanium based composite which includes a Ti(Al,O) base matrix, discrete ceramic particles, and an oxide layer on the surface of the composite. The discrete ceramic particles are integrally associated with the Ti(Al,O) base matrix and the oxide layer, so that at a temperature of above about 600° C., the composite is substantially resistant to oxidation and spallation.

Abstract: Titanium based metal matrix composites reinforced with ceramic particulate are well known, based on a blend of titanium alloy powders with ceramic powders, e.g., aluminum oxide powders, utilizing a low energy ball milling process, followed by cold compacting and sintering to produce an appropriate composite. This prior art process is disadvantaged from the point of view that there are virtually no particles in the blend below the micrometer size range, which lack has a deleterious effect on the subsequent processing of the composite. This problem has been overcome by utilizing dry high energy intensive milling in the process, which has the effect of providing the necessary number of small particles below the micrometer size range as well as enhancing the reactivity of different particles with one another.
