Abstract

In the framework of a diffusion-limited model, the effect of homogenization treatment following precipitate dissolution for a spherical and a planar geometry was considered. It was shown that, for a planar precipitate, the time for complete homogenization is considerably larger than the time required for the precipitate dissolution by approx. two orders of magnitude. For a spherical geometry, it was found that the concentration in the center of the dissolved precipitate at the instant of its dissolution decreases to a value lower than the equilibrium solubility value at the matrix/precipitate interface. The model is applicable for spherical particles larger than approx. 5 to 500 nm, when the influence of the particle curvature can be neglected.
