Abstract：

Hot compressive deformation of TC6 titanium alloy was carried out on the Thermecmaster\|Z Hot\|simulator over the range of deformation temperature from 800℃ to 1040℃, strain rate from 10 -3 s -1 to 50 s -1 ,and maximum deformation degree 50% The experimental results have shown that the optimal process parameters are the temperature of 920～950℃ and strain\|rate of 1 0～1×10 -3 s -1 After the effect of deformation temperature,strain and strain rate on flow stress were studied, a high precision constitutive equation based on the regressive analysis was presented
