Abstract

In order to improve the mechanical properties and casting properties of AZ63 magnesium alloy

different content elements including Y

Sn and Ca were added. The composition of the new Mg alloy AZ63 optimized by orthogonal experiment is as follows: 0.5%Y

9.5%Nd

0.5%Sn and 0.5%Ca. The mechanical properties of AZ63H alloy were tested. The results show that as-cast tensile strength and elongation of the alloy reach 235 MPa and 8.3%

respectively

while after the T6 heat treatment

they are 289 MPa and 11.8% respectively. The new Mg alloy exhibits the better mechanical properties compared with conventional Mg alloys.
