Abstract:
A method of making a densified sintered titanium article includes forming a powder bed of a titanium feedstock. A binder is applied to a portion of the powder bed to bind the titanium feedstock together, thereby forming a green body. The green body is debinded to remove at least a portion of the binder to form a debinded titanium article. The debinded titanium article is sintered at a sintering temperature in an atmosphere comprising hydrogen to produce a sintered titanium article. The sintered titanium article is held at a phase transition temperature to form a microstructure-controlled titanium article. The microstructure-controlled titanium article is dehydrogenated to form a densified sintered titanium article.
