Using electromagnetic fields application ways, AZ80 magnesium alloy is semi-continuously cast into billets with diameter of 165 mm. And the dynamic recrystallization (DRX) evolution of the semi-continuous cast AZ80 magnesium alloy during hot compression has been experimentally studied on Gleeble 2000 thermal-mechanical simulator, at temperatures from 260 to 410 °C and strain rates from 0.001 to 10s-1. It is found that the chief microstructure evolution is dynamic recrystallization, and the effect of deformation process parameters on DRX evolution is analyzed. The mathematical models including critical recrystallization model, kinetics model and grain size model of DRX are established and the results show good agreement between experiments and the models.
