[0002] Magnesium alloy is the lightest non-ferrous metal alloy. It has the advantages of light weight, good damping and shock absorption performance, and easy processing and forming. It is widely used in aviation, aerospace, transportation, communication, and electronics industries; but magnesium alloy has low strength. , low hardness, poor corrosion resistance, and poor thermal stability have greatly limited the application of magnesium alloys
[0003] In order to improve the mechanical properties of magnesium alloys, rare earth materials are often doped in magnesium alloys, such as yttrium, samarium, terbium, etc. The addition of rare earth elements greatly increases the cost of magnesium alloys. Plasticity, which makes the plastic forming of magnesium alloys difficult and limits the application range of magnesium alloys
