近年来,以计算材料科学为基础,试错性材料设计法正在向理论性材料设计法迈进,并且已进入实用化的新阶段。相场法(phase-field method,以下简称PF法)是基于连续体模型,研究材料组织形成过程现象的一种模拟方法。日本名古屋工业大学小山敏幸介绍了PF法的计算要点,并以钛合金为对象举例加以说明。
In recent years, based on computational materials science, trial-and-error material design is moving forward to the theoretical material design approach and has entered a new phase of practical application. Phase-field method (hereinafter PF method) is a simulation method based on continuum model to study the phenomenon of material microstructure formation. Yoshinobu Yamauchi, Nagoya Institute of Technology, Japan, introduced the calculation of the PF method and gave an example of the titanium alloy.
