In　this　study,　(TiBw,　+　TiCp,)/Ti　composites　reinforced　with　various　volume　fraction　were　prepared　by　in　situ　casting　route　and　subsequent　(alpha　+　beta)　forging.　The　relationships　among　reinforcement　volume　fraction,　microstructure　and　tensile　properties　of　the　composites　are　investigated　and　discussed.　The　results　indicate　that　the　aspect　ratios　of　the　reinforcements　are　reduced　and　relatively　uniform　distribution　of　the　reinforcements　is　obtained　after　(alpha　+　beta)　forging.　Meanwhile,　with　the　increase　in　volume　fraction　of　reinforcement,　the　a　phase　is　significantly　refined　due　to　dynamic　recrystallization　(DRX).　The　tensile　testing　results　indicate　that　the　yield　strength　and　ultimate　tensile　strength　of　the　composites　exhibit　a　rising　trend　with　the　volume　fraction　of　reinforcements　while　the　elongations　gradually　reduce　both　at　RT　and　elevated　temperature.　With　the　increasing　of　tensile　temperature,　the　ultimate　tensile　strength　of　the　composites　obviously　decreases　while　the　elongation　increases.　The　strengthening　mechanism　as　well　as　the　softening　phenomena　is　discussed.
