N2 - In this paper, the flow stress model has been established based on the isothermal compression data at deformation temperature of 800∼1050°C, strain rate of 0.001∼0.1 s-1 with the help of the Zener-Hollomon parameter and the Arrehnius' equation. For the forging of Ti-6.0Al-2.0Zr-1.0Mo- 1.0V alloy with 3.0 mm in thickness and 66.0 mm in height, the equivalent stress, strain, strain rate distribution and temperature rise in the superplastic extrusion process have been simulated through FEM. The simulated results show that the punch velocity has significant effect on the equivalent stress, temperature rise and extrusion load.
