摘要：In order to study the flow behavior of TA12 titanium alloy at high temperature and set up the constitutive model that accurately describes its flow behavior at high temperature, the tensile tests at the temperatures of 700-850 ℃ and at strain rates of 0.001-0.1 s-1 were carried out. The results show that, under the deformation conditions, the flow stress increases with the increase of strain, and then decreases gradually after reaching the peak stress until the material breaks and the steady flow stress occurs at 850 ℃ and 0.001 s-1. Considering the effects of strain hardening, strain rate hardening and thermal softening, a modified JC constitutive model was proposed. It can accurately describe the flow behavior of TA12 titanium alloy at high temperature. © 2019, Science Press. All right reserved.
