To obtain composites of titanium reinforced with ceramic particles is proposed in this paper, and for this reason it turns out to be fundamental to evaluate the reactivity between the matrix and reinforcement. Both titanium nitride and carbide (TiN and TiC) are investigated as materials of low reactivity whereas titanium silicide (TiSi<sub>2</sub>) is also studied as materials of major reactivity, already stated by the scientific community. This reactivity will be analyzed by means of scanning electron microscopy (SEM) there being obtained distribution maps of the elements that allow to establish the possible influence of the sintering temperature and time. Hereby the matrix-reinforcement interactions are optimized to obtain suitable mechanical properties. ER -
