Machine calculations were made of the dynamics of a set of atoms simulating a crystal undergoing radiation damage. Work on copper is reviewed briefly, and its extension to a simple model of ordered Cu/sub 3/Au is described. Investigations of lattice agitation in the wake of a damage event and the extent to which a thermal spike model has validity are discussed. Information on point defects and clusters of point defects in copper is another by-product of the calculations. Recent extensions of the calculations to a model of alpha -iron are reported. Although a satisfactory interatomic potential was not found, it appears that the easy direction for production of a displacement is (100) and that the interstitial in this lattice has a split configuration with (110) orientation.
