Abstract

Numerical and approximated analytical solutions for the multicomponent growth of spherical precipitates with capillarity effects are presented. Coates' interface velocity contours are presented when the diffusivity of the precipitate components differs by several orders of magnitude. They show that the effect of capillarity in spheres is to reduce the thickening rate, such that a particle that would grow under a regime where there is no long-range partitioning of the slow diffuser, can be shifted into a regime where such partitioning is necessary.
