摘　　要：研究了过冷Ｇｅ(７３．７)Ｎｉ(２６．３)合金熔体的Ｎｉ，Ｃｕ，Ｓｉ原子团簇触发凝固，发现触发凝固起始温度显著高于未经触发凝固起始温度。Solidification of undercooled Ge73.7Ni26.3 alloy melt triggered by Ni, Cu, Si clusters wasstudied. The initial solidification temperature is much higher than that without cluster triggers. ThecluSter-induced nucleation was analyzed in order to reveal the difference from the classical nucleationtheory.
