Abstract

An approach in titanium powder metallurgy called “decomposition sintering” of the hydride is described in connection with some of its unique characteristics. Hydriding and dehydriding of titanium are a function solely of ambient temperature and hydrogen pressure. Thus, raw titanium was readily hydrided and powdered, and the powders were readily converted to massive metal in a single operation comprised of ram pressing in vacuum at elevated temperature, i.e., decomposition to metal during the sintering process. The important aspect of ductility was retained by sufficient dehydriding, and by other impurity control as needed for titanium.
