Abstract
This is a powder metallurgy method for producing fully dense compacted articles from powder charges of hydride-forming alloys, preferably titanium base alloys. The powder is hydrided, sealed in a collapsible container, heated to an elevated temperature and then hot compacted to produce a substantially fully dense article, which is then dehydrided, reheated and again compacted to remove any voids formed during dehydriding. The final article is characterized by relatively fine grain size and excellent formability.
