Undercooling behavior and amorphous formation of a drop-like Pd₄₀Cu₃₀Ni₁₀P₂₀ alloy

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 atmosphere 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.
