Abstract
The invention relates to a process for the manufacture by sintering of a titanium part, characterized in that is consists of: (a) mixing a titanium hydride powder with a temporary binding agent, (b) injecting the mixture obtained into a mold to obtain a part in the desired shape, (c) removing the binding agent, (d) heating the part 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 reached, and (f) cooling the part in a non-reactive gas atmosphere.

A process for the manufacture by sintering of a titanium part, comprising the steps of:
- (a) mixing a titanium hydride powder with a temporary binding agent,
- (b) injecting the mixture obtained into a mould;
- to obtain a part in the desired shape,
- (c) removing the binding agent,
- (d) gradually heating the part in a hydrogen atmosphere up to a desired sintering temperature,
- (e) replacing the hydrogen atmosphere by a non-reactive atmosphere once the sintering temperature has been reached, while keeping the part at said sintering temperature for between 5 and 60 minutes, and
- (f) gradually cooling the part in a non-reactive gas atmosphere.
