In this paper, βTitanium alloy was prepared by vacuum melting, cold deformation, and solution treatment. A six-anvil high press was used to perform high-pressure aging treatment on β-Titanium alloy, and the effects of high-pressure aging parameters on the microstructure, microhardness and elastic modulus of βTitanium alloy were studied, and the aging kinetics was analyzed. It is found that, aging pressure and time have significant effects on microstructure, hardness and elastic modulus. With the increase of pressure and time, the precipitation of α phase and martensite phase increases. The pressure and time of high-pressure aging have significant effects on the modulus of microhardness and elasticity. As the pressure increases, the microhardness first decreases and then increases, and the elastic modulus increases; as time increases, Vickers hardness and the elastic modulus first increase and then decrease.
