Abstract The effect of Y Content on as cast microstructure and mechanical properties of Mg-10Gd-xY-1Zn-0.5Zr(x=1,2) magnesium alloy was studied. The results show that the microstructure of Mg-10Gd-xY-1Zn-0.5Zr (x=1,2) magnesium alloy is composed of α-Mg,Mg₁₂(Gd,Y)Zn,Mg₅-(Gd,Y,Zn) and Mg₂₄(Y,Gd,Zn)₅ phases. When the content of Y increases from 1% to 2%, the content of second phases such as Mg₁₂(Gd,Y)Zn and Mg₅(Gd,Y,Zn) decreases, while the Mg₂₄(Y,Gd,Zn)₅ phases increases.With the increase of Y content, the mechanical pro-perties of the alloy at room temperature are obviously improved. When the Y content is 2%, the as-cast tensile strength, yield strength and elongation are 237 MPa, 189 MPa and 4.6% respectively, which are significantly improved compared with 1%, indicating that Y has obvious advantages in improving the comprehensive properties of magnesium alloy.
