将团簇变分法中B2相的自由能引入相场法中，并将由此得到的长程有序和短程有序参数随时间的演化与均匀极限下的路径概率法得到的结果进行了比较。这意味着相场法和路径概率法之间存在着密切的联系。此外，研究了无序-B2相变的非均匀微结构演化过程。结果定性地再现了Fe-Al系的实验结果。
The free energy of the B2 phase within the Cluster Variation Method is incorporated in the Phase Field method and the resultant time evolutions of Long Range Order and Short Range Order parameters are compared with the ones obtained by the Path Probability Method in the homogeneous limit. It is implied that there exist closed correlations between the Phase Field and Path Probability Methods. Furthermore, heterogeneous microstructural evolution process is investigated for a disorder-B2 transition. The results qualitatively reproduce the experimental results of Fe–Al system.
