Abstract
The hot compression deformation of AZ81 magnesium alloy after deformation was carried out on Gleeble-3800 thermal simulator, and the hot deformation characteristics were studied. The maximum true strain is set to 0.7, the deformation temperature is 300 °C, 350 °C, 400 °C and 450 °C, and the deformation rate is 0,01 s-1, 0,1 s-1 and 1 s-1. The hot processing map was calculated and drawn, and the microstructure of different compression processes was compared. The results show that the deformation temperature is ( 400 ± 20 )°C, the strain rate is 0,1 s-1, and the crystal is fine and uniform, which is the best hot processing parameters.
