Abstract

With the microscopic phase-field dynamic model, the effect of elastic strain energy on the incubation period of Ni-Cr-Al alloys is studied. The simulation results demonstrate that elastic strain energy does not change the precipitation sequence of alloys. There exits the incubation period of DO ₂₂ phase and L1₂ phase in the alloys with different precipitation sequence. If DO₂₂ phase precipitates first, the incubation periods of both phases are prolonged with the elastic strain energy increased. If L1₂ phase precipitates first, with the increase of elastic strain energy, the incubation periods of L1₂ phase is shortened while that of DO₂₂ phase is prolonged.
