摘要：
The deformation behavior of Cu-0.6Cr-0.03Zr alloy was investigated by compression test on Gleeble-1500 hot-simulation machine in the temperature range of 550-750℃ and the strain rate range of 0.01-5 s-1. The hot deformation constitutive equation and processing map were established. The results show that the flow stress decreases with increasing the deformation temperature and increases with increasing the strain rate. The flow stress behavior is expressed by hyperbolic sine equation containing Zener-Hollomon parameter, and the hot deformation activation energy is calculated as 572.05 kJ/mol under the present experimental condition. There are three safe processing zones for high temperature deformation of the alloy. The optimum domain for hot working occurs at 770-800℃ and 0.01-0.05 s-1, with the efficiency of power dissipation of 32%-40%. © 2020, Science Press. All right reserved.
