摘要：
The dynamic recrystallization behavior of TC21 alloy during hot compression deformation was investigated at 870 similar to 990 degrees C and strain rate of 0.001 similar to 40 s(-1) on a Gleeble-3500 thermo-simulation machine. The results show that dynamic recovery and dynamic recrystallization occurs during hot deformation. As the deformation temperature increases and strain rate decreases, the softening caused by dynamic recrystallization is more obvious. According to the relevance of flow stress, strain rate and deformation temperature, the dynamic recrystallization activation energy is obtained. The constitutive equation and dynamic recrystallization kinetics motel are set up through analyzing and calculating the data of thermo-simulation.
