Abstract
A numerical solution has been obtained which gives the morphological changes and kinetics during the coalescence of two spheres by surface diffusion. The solution may be utilized for determining surface diffusion coefficients by observing the coalescence of two gas bubbles within a solid or interfacial diffusivities by observing the same phenomenon involving spherical precipitates in a solid matrix. The former parameters are of great interest in the fission-gas swelling of nuclear fuels whereas the latter figure prominently in various transformations in the solid state. The present analysis provides a theoretical framework by which these parameters may be determined under conditions of minimal absorption difficulties, as well as guidelines for applicability of the results.This publication has 5 references indexed in Scilit:
