[0002] Magnesium and magnesium alloys are the lightest non-ferrous metal structural materials, which can be used in machinery, electronics, aviation, medicine, and daily industries. They have high specific strength, specific modulus, and excellent processing performance; however, magnesium and magnesium Low alloy strength, low hardness, poor corrosion resistance, poor wear resistance, high expansion coefficient, and poor high temperature resistance have greatly limited the application of magnesium and magnesium alloys; therefore, the mechanical properties of magnesium and magnesium alloys must be studied. Only by making improvements can the application range of magnesium and magnesium alloys be expanded
