A process for forming a high- strength metal alloy material having a predetermined chemical composition, comprises mixing a particulate enriched metal alloy which contains at least one alloy constituent in an amount at least 10% greater than desired in the final alloy material and which has a particle size of less than 40 mesh, with a particulate metal filler having a particle size of less than 40 mesh, the two particulate metals being mixed in such proportions such that the resultant mixture contains alloy constituents in the proportions desired in the final alloy material, passing the powder mixture through a powder-rolling mill to compact the same to form a solidified mass having a density of at least 80% of theoretical, and sintering the solidified mass at a temperature sufficient to cause interparticle bonding and diffusion of the alloy constituents to form a homogeneous mass of metal alloy material having the desired chemical composition. The alloys and filler metal may be of Al or Ti. |
