摘要：
In this paper we report the formation of a new Pr-55 Al-12 Fe-30 Cu-3 bulk metallic glass. Cylindrical Pr-55 Al-12 Fe-30 Cu-3 specimens of 5 mm in diameter and 100 mm in length were prepared by copper mold suction casting. Differential scanning calorimetry results indicated that the Pr-based bulk metallic glass system has a wide supercooled liquid region about 64K. The melting temperature of the amorphous state is about 140K higher than that of its crystalline state. Hysteresis loops were measured, and the results indicated that the Pr-55 Al-12 Fe-30 Cu-3 bulk metallic has hard magnetic property, while the completely crystallized alloy has soft magnetic property at room temperature.
