Notes:
In this paper, the flow stress model has been established based on the isothermalcompression data at deformation temperature of 800~1050oC, strain rate of 0.001~0.1 s-1 with thehelp of the Zener-Hollomon parameter and the Arrehnius’ equation. For the forging ofTi-6.0Al-2.0Zr-1.0Mo-1.0V alloy with 3.0 mm in thickness and 66.0 mm in height, the equivalentstress, strain, strain rate distribution and temperature rise in the superplastic extrusion process havebeen simulated through FEM. The simulated results show that the punch velocity has significanteffect on the equivalent stress, temperature rise and extrusion load
