Abstract

The Cu₃₆Zr₄₈Ag₈Al₈ alloy exhibits very high glass-forming ability. We have succeeded in synthesizing a Cu₃₆Zr₄₈Ag₈Al₈ bulk glassy alloy with a diameter of 25 mm using the conventional copper mold injection casting. The absence of a crystalline phase was confirmed by X-ray diffraction and differential scanning calorimetry examinations. The critical cooling rate for formation of a glassy phase for the Cu₃₆Zr₄₈Ag₈Al₈ alloy was estimated to be less than 6.4 K/s. High glass-forming ability and high strength might contribute to its commercial application for the Cu₃₆Zr₄₈Ag₈Al₈ bulk metallic glass.
