Abstract

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-A1 system.
