An analytical model of the development and growth of embryos in a polycrystalline material during a phase transition at the intergranular slope boundary is proposed. The model assumes the presence of faces that are oriented crystallographically parallel to the forming boundary and are characterized by reduced surface energy. In this case, the faces refer to the densely packed plane of the lattice of matching nodes. The results obtained in the work on the evaluation of the parameters of the formed facets and the total testing time are confirmed by generalized experimental data.

Keywords: phase transitions, defects, microstructure, facets, boundary geometry, specific surface energy
