Hot compression tests of AM80 magnesium alloy were performed on the Gleeble-1500 machine to obtain the flow curves under temperatures of 300, 350, and 400°C and strain rates of 0.01, 0.1 and 1s-1. The work hardening curves were predicted by the Avrami kinetic. A new approach, which considered the yield stress during compression, was used to simulate the microstructural evolution and the volume fraction recrystallized for AM80 magnesium alloy. The simulated results were in good agreement with experimental findings.
