Phase-field simulation of the influence of elastic field on microstructure evolution and equilibrium composition of precipitation

We have simulated the microstructure evolutions of coherent single precipitate and multi-precipitates with inhomogeneous eigen elastic field and applied external strain using phase-field method. The influences of the inhomogeneous eigen elastic field and applied external strain on the morphology pattern of the coherent precipitate are discussed, and the effect of the elastic field on the equilibrium compositions of the precipitate and the matrix phase is also analyzed.
