The hot compress testing of as forged β-CEZ titanium alloy at 800-1000℃, strain rate of 0.01-10 s-1and the deformation degree of 0.7 was done on a Gleeble-3800 simulator. The influences of deformation temperature and strain rate on the stress were studied according to true stress-true strain curves, and the constitutive equations of β-CEZ titanium alloy during hot deformation were established based on hyperbolic sine equations of Arrhenius type and Z parameter. The results show that the flow stress of β-CEZ...
