摘要：

To understand the hot compression deformation characteristics of the self-developed Al-9.3Zn-2.4Mg-1.1Cu alloy,the hot compression tests of Al-9.3Zn-2.4Mg-1.1Cu alloy were investigated by Gleeble 1500 thermo-mechanical simulator to determine the best hot processing conditions.The hot deformation temperatures were 300,350,400,and 450 ℃,and the strain rates were 1,0.1,0.01,and 0.003 s-1,respectively.Based on the experimental results,the constitutive equation and hot processing maps are established,and the corresponding strain rate and temperature-sensitive index are analyzed.The results show that Al-9.3Zn-2.4Mg-1.1Cu alloy has a dynamic softening trend and high strain rate sensitivity during the isothermal compression process.The hot deformation behavior can be described by an Arrhenius-type equation after strain compensation.The temperature has a negligible effect on the hot processing properties,while a low strain rate is favorable for the hot working of alloy.The processing maps and microstructure show that the optimal processing conditions were in the temperature range of 400-450 ℃ and strain rate range of 0.003-0.005 s-1.
