Research on the Mechanical Properties and Corrosion Resistance of Mg-RE and Mg-Zn-Cu Alloys

Rare earth magnesium alloys and Mg-Zn-Cu alloys were prepared by gravity casting and direct squeezing casting respectively, and the corrosion performances of three kinds of Mg-Zn-Cu alloys were compared in this paper. The results indicate that adding rare earth elements and direct squeezing casting process can significantly increase the mechanical properties of magnesium alloys, and aluminum can improve the corrosion resistance of magnesium alloys.
