Abstract
Powder metallurgy production of Ta10W alloy affording properties comparable to melt derived Ta10W, but at higher yields and lower costs, is enabled by blending component powders of minus 325 mesh and sintering at 2,400.degree. C. in three sinter steps and utilizing a slow ramp up in the first sinter step and cold isostatic pressing prior to the first sinter step and isostatic press densification in conjunction with at least the first sinter step.
