TC4 titanium alloy was treated at pressure of 1~5 GPa and 930℃ for 20 minutes, its hardness and compressive strength at room temperature and high temperature were measured by mechanics machine, and according to the microstructure analysis, the effect of high temperature-high pressure treatment on mechanical properties of TC4 titanium alloy was discussed. The results show that the high temperature-high pressure treatment can increase the hardness and compressive strength of TC4 titanium alloy, and in the pressure range of 1GPa to 5GPa, the hardness and compressive strength of the alloy change slightly with the increase of pressure.
