Based on the principle of multi-element and small amount of alloying

rare earth elements such as Y

Nd

La

Ce

and Zr were added to Mg to prepare a novel magnesium alloy

and the mechanical properties and corrosion properties were measured. The results show that the tensile strength of Mg-Y-Nd-（La+Ce）-Zr magnesium alloy with 4.2%Y

2.7%Nd

0.1%（La+Ce）

and 0.5%Zr reaches 223 MPa

presenting desirable mechanical properties. In addition

the average corrosion rate of the alloy is 0.209 mg/（cm~2·h） in Hank’s solution for 96 hours.
