Abstract:The preparation of in-situ particulate reinforced titanium alloy matrix composites in recent years were reviewed, which includes powder metallurgy, melting-casting, XDTM (Exothermic Dispersion), SHS(Self-propagating High-temperature Synthesis), SHS-melting- casting, CR(Contact Reaction ), MA(Mechnical Alloying), laser-melting cladding et al. Microstructures of carbide and boride reinforced respectively titanium alloy matrix composites by different fabrication methods were reviewed. The carbide reinforcements include TiC, Ti2AlC, Ti3AlC et al. The boride reinforcements include TiB2 and TiB. The morphology of reinforced phase were analyzed respectively. Future prospect for these titanium alloy matrix composites was discussed.
