Titanium group powder metallurgy

Abstract

Methods and compositions relating to powder metallurgy in which an amorphous-titanium-based metal glass alloy is compressed above its glass transition temperature Tg with a titanium alloy powder which is a solid at the compression temperature, to produce a compact with a relative density of at least 98%.

1 . A powder manufacturing method for manufacturing an titanium group alloy product comprising the steps of blending from about 1 to about 25 volume percent of an amorphous metal powder having a glass transition temperature Tg, with from about 75 to about 99 volume percent of an titanium group metal powder, and compressing the blend at a temperature of at least Tg to produce a metal component having a density of at least 98% with about 2 percent or less porosity.
