摘要Bulk metallic glasses are prepared in Pd40.5Ni40.5SixP19-x (x=0$--14 at.%) alloys by a combination of flux treatment and water quenching technique. It is found that the thermal stability of the Pd40.5Ni40.5SixP19-x glassy alloys depends on the addition of Si content. Among the Pd40.5Ni40.5SixP19-x glassy alloys studied, the Pd40.5Ni40.5Si5P15 bulk metallic glass exhibits the largest supercooled liquid region (△T=119,K) and the highest activation energy of crystallization (283.3kJ/mol), showing enhanced glass formation ability and extraordinary glassy thermal stability.
