The establishment of thermal processing map of medical AZ81 magnesium alloy
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 deformat...

| Summary: | 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<sup>-1</sup>, 0,1 s<sup>-1</sup> and 1 s<sup>-1</sup>. 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<sup>-1</sup>, and the crystal is fine and uniform, which is the best hot processing parameters. |
