Abstract

MD simulations of displacement cascades in a variety of metals of different crystal structure and an ordered alloy are discussed. Frenkel-pair production at the end of the cascade process is well below the NRT theoretical value in all cases and a new empirical relationship between Frenkel-pair number and damage energy is assessed. In contrast with this, antisite production efficiency in ordered alloys increases with increasing energy, as does the atomic mixing of the different atomic species. The degree of clustering of interstitials in cascades is materialdependent. These results are discussed in relation to the highly disordered zone formed in the thermal spike.
