Abstract

The invention relates to a process for the manufacture, by sintering, of an article made of titanium, characterised in that it consists in: - (a) mixing a titanium hydride powder with a temporary binder, - (b) injecting the mixture obtained into a mould to obtain an article of desired shape, - (c) removing the binder, - (d) heating the article under a hydrogen atmosphere up to the desired sintering temperature, - (e) replacing the hydrogen atmosphere with vacuum or an unreactive atmosphere once the sintering temperature has been reached, and - (f) cooling the article in the atmosphere of the unreacted gas.
