深过冷条件下均质形核的非平衡热力学探讨

Investigation on Non-equilibrium Thermodynamics of Uniform Nucleations During Large Undercooling

本文从非平衡热力学的角度，分析了纯金属深过冷条件下的均质形核问题。导出了均质形核的驱动力和界面自由能表达式。纯铝验证计算的结果与其他人的数据接近。

Uniform nucleations of pure metals during large undercooling are analyzed in present paper from the view of non-equilibrium. Expressions for the nucleations and the interface's free energy are established, and the results from the expressions are very consistent with other person's data.
