We simulate the diffusional evolution of microstructures pro- duced by solid state diffusional transformations in elastically stressed binary alloys in two dimensions. The microstructure con- sists of arbitrarily shaped precipitates embedded coherently in an infinite matrix. The precipitate and matrix are taken to be elastically isotropic, although they may have different elastic constants (elas- tically inhomogenous). Both far-field applied strains and mismatch strains between the phases are considered.
