Titanium matrix composites (TMC) reinforced with particulate ceramics, have attractive properties for aeronautic applications. Powder metallurgy is the main route of elaboration of these TMC. However, processing these composite poses difficulties as Ti is difficult to mill and does not achieve full density when using standard sintering. Hydrogen can be used as a temporary alloying element to help improve titanium powder metallurgy processing. The first part of the study consisted of comparing sintering of Ti and TiH2. This was done in a dilatometer for several temperatures. The sintered samples were then characterized in terms of microstructure and density. In the second part, TiH2 was used in an example for the application of titanium matrix composites reinforced with particulate TiC. The obtained materials were characterized (microstructure, density). Finally, tensile tests were performed on the TMC and compared with results from the literature.
