摘要：

The elastic fields associated with a dispersion of spherical particles in an isotropic matrix are determined using the equivalent inclusion approach of Moschovidis and Mura. The coherent particles possess a misfit strain and have elastic constants different from those of the matrix phase. A spatially nonuniform stress field can be applied to the system. The stress fields are used to calculate the equilibrium compositions at the precipitate-matrix interface for use as diffusional boundary conditions in computer simulations of multiparticle coarsening in elastically stressed systems.
