摘要：

Based on the microscopic phase-field kinetic model, the evolution of Ni75Cr16.4Al8.6 alloy in the later stage of coarsening was studied using the structure function normalized factor and scaling function. The simulation results show that both the curves of scaling function of L1(2) phase and DO22 phase present scaling behavior in the coarsening process. Without elastic strain energy, the peak values of structure function normalized factor and scaling function of DO22 phase are higher than that of L1(2) phase. When the elastic strain energy is added, the curve peaks of both phases become smaller. It means the growth of both phases are stunted by strain energy; compared with L1(2) phase, the decrease extent of DO22 phase is larger; peak values of structure function factor and scaling function of L1(2) phase are higher than that of DO22 phase. The strain energy plays a greater role of restriction on DO22 phase.
