Self-diffusion in model Al and Ni has been studied by molecular static and molecular dynamictechniques. The structure of defect-lattice configurations has been obtained with the former technique.With the latter, the vacancy diffusion mechanism has been analysed over a wide temperaturerange, and particular attention has been paid to multiple jumps in the high temperature region.The possible contribution of divacancies, within the limits imposed by the interatomic potentials used, has also been considered.
