We examined the undercooling behavior and bulk state amorphous formation of a drop-like Pd40Cu30Ni10P20 alloy using the high frequency heating and melting apparatus by 1 kW power supply. In view of the high undercooling liquid formation ability of the above alloy, we used a combination of two solidification processes: the slow cooling solidification until just before nucleation temperature in vacuum atomosphere and just after He gas jet cooling. As a result, we have shown the undercooling solidification and the newly bulk state amorphous formation process of Pd40Cu30Ni10P20 alloy in detail.
