ABSTRACT:
A sintered powdered titanium alloy article is provided which has a density approaching theoretical and which is characterized by having physical properties similar to those of a wrought titanium alloy article having the same chemical composition. This unique article is produced by a novel process which comprises (a) providing milled alloy forming particles having a median particle size by weight of 20 microns or less, with the alloy forming particles being alloyable with titanium; (b) mixing the as milled alloy forming particles with titanium base particles having a median particle size by weight of greater than 40 microns so as to form a particle mixture capable of being sintered to near theoretical density which mixture contains a minor amount of alloy forming particles; (c) compacting the mixture of as milled alloy forming particles and titanium base particles into an article of the desired configuration having a green density sufficient to render the so-produced article capable of being sintered to near theoretical density; and (d) sintering the article at a temperature below that at which any liquid phase is formed in the article to produce a sintered article which has a density approaching that of theoretical.
