In this paper, a near beta titanium alloys reinforced with different weight fraction of SiCp were prepared by vacuum induction melting technology.The addition of SiCp was 0wt.%,0.1 wt.%,0.4wt.%,1.0wt.% respectively. Effect of SiCp addition on microstructure and mechanical properties of near beta titanium alloys was systematically investigated by XRD,SEM ,Vicker’s micro- hardness tester and Instron universal testing machine.The XRD patterns of the composite materials were α-Ti,β-Ti and TiC phase.The addition of SiCp refined prior β grain size obviously and the grain size in the alloy decreased from 639 to 323 μm with the addition of SiCp range from 0 to 1wt.%.Moreover, the Vicker hardness and compression strength were higher but worse plasticity compared with unreinforced titanium alloy. These composites utilize the strengthening effects of both particulate reinforcements of TiC and Si elements through solid solution hardening, fine grain hardening.
