Oxide inclusion existed in cast Mg-Gd-Y-Zr alloy was analyzed by SEM(scanning electron microscope)and XRD(X-ray diffraction).The results indicate that the ternary oxides of Zr0.7Y0.28O1.862 and Zr1.894Gd1.894O7 are observed besides the Mg oxide inclusion which is often found in the popular Mg alloy
which is attributed to the oxidation of Y
Gd and Zr.Based on the mechanism of the flux component purifying the Mg-Gd-Y-Zr alloy
a model is presented for describing the formation and movement of the inclusions in the alloy.
