Title: Diffusion-controlled dissolution of a spherical precipitate in an infinite binary alloy

Abstract

An exact numerical solution of the dissolution kinetics of spherical precipitates was obtained from the Green's function method and compared with previous approximate solutions. The same equation can be used to simulate the growth of precipitates having a non-zero initial radius. The Green's function method is useful to predict the kinetics of dissolution or growth in case the solubility is not very small or the solvus curve extends into the interior of the phase diagram. The influence of capillarity on the dissolution kinetics can be incorporated in the present formalism.
