Abstract : A model is presented for the dissolution of a precipitate in which solute transfer occurs by volume diffusion of material away from the precipitate in the matrix. The predicted dependence of dissolution kinetics on growth mode is a consequence of the fact that the concentration profile ahead of a growing precipitate is a function of the diffusion path.
