    Abstract:

    The microstructure evolution of coherent precipitates was simulated with the phase-field model by computer and the influence of different strain energy on the precipitation morphology was also discussed. Results show that when the coherent strain energy is 0, spherical-shaped precipitates or flocculent structure distribute randomly with isotropic morphology. With the elastic strain energy increasing, the arrangement orientation increases, quasi-periodical macro lattice structures and sandwich-shaped structures are formed with anisotropic morphology. The simulation results are in good agreement with the experimental
