A reaction-rate theory model of impurity-induced vacancy clustering and micro-void formation has been used to interpret the positron annihilation data of Dlubek et al. (1979) on the recovery of cold-worked Ni-Sb alloys. The calculated mean microvoid sizes agree well with the experimental data. The model predicts the time and temperature-dependent microvoid density for a given impurity concentration.
