When Fe–16.2mol%Si–13.3mol%V alloy is homogenized at 1473 K for 7.2×103 s and then quenched into iced brine, D03 (ordered bcc) particles appear in the A2 (disordered bcc) matrix. The D03 particles are cuboidal because of the influence of elastic energy which arises from the lattice mismatch between the A2 matrix and the D03 particle. When the two-phase microstructure of A2+D03 is aged at 923 K, the phase separation of D03 precipitate takes place and fine A2 particles appear in each cuboidal D03 particle. In the course of further ageing at 923 K, the A2 particles coarsen to become plates in the D03 particles as a result of elastic energies, then the A2 plates elongate along {100} to reach the A2 matrix surrounding the D03 particles, and finally the split of D03 particles is realized. Such a split phenomenon takes place throughout the microstructure to bring the refinement or at least the decelerated coarsening of two-phase microstructure, which is a result of not only the elastic energies but also the chemical free energy.
