The lattice distortion around a vacancy in F.C.C. metals

This is the authors' abstract. We don't add key points for this paper.

The lattice distortion produced by an isolated vacancy in aluminium and the noble metals has been calculated using a discrete lattice model which assumes non‐equilibrium pairwise interactions extending out to second nearest neighbours. It is shown that, to first order, the relaxation volume associated with a vacancy can be expressed in terms of the elastic constants. For aluminium the asymptotic displacement field calculated from the lattice model is compared with the corresponding elasticity results.
