摘要

Ti-40 wt% TiC and Ti-6Al-4 V- 40 wt% TiC metal matrix composites were obtained by the hydrogenated powder metallurgy approach, followed by post-sintering densification by hot pressing. The composites obtained were characterized by high hardness values, which were 700–1300 HV due to nearly-dense microstructure, high content of reinforcing titanium carbide particles and non-uniform redistribution of reinforcing phase in the matrixes. The high hardness of the composites in the as-densified state resulted in a significant improvement of ballistic performance of two-layer Ti-based metal matrix composites. It is shown that the proposed approach for the manufacturing of layered Ti-based metal matrix composites is promising for practical application.
