The effect of partial substitution of Y for Gd on the glass forming ability of Mg65Cu15Ag10Y10 alloy has been studied using X-ray diffraction and differential thermal calorimetry. Partial substitution of Y by Gd improves the glass forming ability. The Mg 65Cu15Ag10Y2Gd8 alloy shows the highest glass forming ability among the alloys investigated, enabling the fabrication of bulk metallic glass with the diameter of 9mm by conventional Cu-mold casting method in air atmosphere. The compressive fracture strength and fracture elongation of the Mg65Cu15Ag10Y 2Gd8bulk metallic glass are 956 MPa and 1.6% respectively.
