Abstract

The stresses developed by misfitting spheres close to a planar free surface have been calculated. It is found that the mean stresses in the neighbourhood of such particles can be large enough to indicate significant increases in the rate of substitutional diffusion. Also, interactions can be so large that the formation of a crater is energetically favourable.
