Surface-Energy Density of Large Spherical Voids in F.C.C. Lattices

Abstract

Abstract An analytical expression has been derived for the number of vacancy–vacancy bonds of large spherical vacancy clusters in a rigid f.c.c. lattice. This permits the relation of the surface-energy density of large spherical voids to the vacancy-formation energy for f.c.c. metals with very-short-range interatomic interaction.
