摘  要:

The solidification behavior and glass forming ability of the Pd-P alloys was investigated by using the copper mold casting and glass fluxing technique. The glass forming ability of Pd-P alloy is found to correlate well with the alloy composition, and the best GFA in this system is identified. The best GFA of Pd-P alloy can be interpreted in terms of a deep metastable eutectic. The eutectic coupled zone of Pd-P alloy was described based on the undercooled solidification experiment.

The microstructures of Pd-P alloys after undercooled solidification (a)△T=5 K, (b) △T=125K, (c) △T=225K, (d)  △T=280 K
