Undercooling experiments of Pd43.5Ni43.5P13 and Pd40Ni40P20 alloys were performed in a 1.2 m drop tube. The effect of cooling rates on the glass formation, nucleation and crystal growth of the Pd40Ni40P20, alloy was studied by filling the various inert gas in the tube. The critical cooling rate for the glass formation in the tube was determined. In addition, it is indicated that the initial temperature of the drop before it droped down is related closely to the nucleation and crystal growth of the alloy.
