Abstract：The hot compression of ZK60 magnesium alloy was carried out on Gleeble1500 thermal simulator at temperature range of 523673 K and strain rates of 00011 s-1 Based on the obtained true stressstrain curves from ZK60 magnesium alloy, the effects of deformation temperatures and strain rates on the peak stress were discussed, and the constitutive equations were established to describe the hot compression of ZK60 magnesium alloy These constitutive equations were applied into finite element analysis software and then the hot compression of ZK60 magnesium alloy was simulated The variation of equivalent effective stress and effective strain in the compressed workpiece was analyzed to find that true stressstrain curves of ZK60 magnesium alloy in hot compression exhibit a obvious dynamic recrystallization characteristic, and the peak stress decreases with increasing the deformation temperature or decreasing the strain rate. The simulated stressstrain curves of are basically consistent with the experimental stressstrain curves, so the constitutive equation can be applied to hot working of ZK60 magnesium
