摘要：
We investigated the glass-forming ability of three Pd-Cu-Ni-P alloys with different compositions (Pd40Cu30Ni10P20, Pd42.5Cu27.5Ni10P20 and Pd42.5Cu30Ni7.5P20) under a continuous cooling condition. The lowest critical cooling rate for glass formation was determined to be 0.067 K/s for the Pd42.5Cu30Ni7.5P20 alloy. The melting behavior indicates that the 7.5% Ni alloy has the nearest eutectic composition of the three alloys. The exceptionally low critical cooling rate of below 0.1 K/s is attributed to the elimination of the primary crystallization that occurs due to off-eutectic composition.
