N2 - In this paper, the flow stress model for the high temperature deformation of Ti-6.0Al-2.0Zr-1.0Mo-1.0V alloy has been established according to the isothermal compression results at a deformation temperature of 800-1050°C, strain rate of 0.01-70.0 s-1. Effects of the process parameters, including deformation temperature, upper ram velocity, shear factor of friction and corner radius, on the strain and stress distribution have been studied during the isothermal extrusion of Ti-6.0Al-2.0Zr-1.0Mo-1.0V alloy. The simulation results show that the deformation temperature, the upper ram velocity and the corner radius of die have significant effect on the strain and stress distribution and the deformation load.
