Dynamics of late-stage phase separation in crystalline solids

The dynamics of Ostwald ripening in elastically stressed crystalline solids is determined through large-scale numerical simulations. Using the insight provided by the simulations, a theory for the dynamics of late-stage phase separation in elastically anisotropic homogeneous solids is developed. Bot h the theory and simulations show that for the systems considered elastic s tress does not alter the exponent of the temporal power law for the average particle size but does affect the amplitude of the power law in a manner t hat is only a function of the symmetry of the particle morphology.
