Abstract: The in-situ synthesized TiB and TiC hybrid reinforced titanium matrix composites have attracted widespread attention due to its high specific strength, high specific stiffness, low density, excellent corrosion and heat resistance. The research status of in-situ synthesized TiB and TiC hybrid reinforced titanium matrix composites were reviewed from the selection of the matrix and reinforcement, introduction method, reaction system, microstructure and mechanical properties, and the prospect of its future development was proposed.
