Near-equiatomic Co-Pt, Fe-Pd and Fe-Pt alloys undergo cubic-tetragonal disorder-order transformation and form three orientation variants. It has been reported that magnetic fieldinduced preferential nucleation of one variant in the initial stage of ordering introduces preferential growth of the same variant in the later magnetic field-free stage [1]. In this study, the effect of preferential nucleation on microstructure evolution in the later stage is studied by phasefield method. The results indicate that the increase in fraction of preferential variant depends on nucleation ratio between the variants, and the stress field originated from the macroscopic shape deformation is the most possible factor affecting preferential growth in the later stage.
