The invention relates to a process for making a workpiece in titanium by sintering, characterised in that it consists in: - (a) mixing a titanium hydride powder with a temporary binder, - (b) injecting the mixture obtained into a mould in order to obtain a workpiece of the desired shape, - (c) removing the binder, - (d) heating the workpiece in a hydrogen atmosphere up to the desired sintering temperature, - (e) replacing the hydrogen atmosphere by a vacuum or a non-reactive atmosphere once the sintering temperature has been attained, and - (f) cooling the workpiece in the atmosphere of the non-reactive gas. |
