On the thermo-dynamical condition for metastable phases formation from undercooled melt in containerless state, we had proposed a criterion, that is, crystals showing a smaller entropy of fusion than that in the equilibrium crystals can be preferentially formed (Material Science and Engineering A, 449-451 (2007) 675). In the present investigation, the validity of this criterion was experimentally verified.

在无容器状态下过冷熔体的亚稳态形成的热动力条件下，我们提出了一个标准，即表现出比在平衡晶体中较小的融合熵的晶体可以优先形成（材料科学和工程A，449-451（2007）675）。在本研究中，该标准的有效性得到了实验验证。
