Interstitial cluster in FCC metals

Abstract
Interstitial clusters in FCC metals have been studied using computer simulation techniques and three different interatomic potentials. The potentials were fitted to both ideal and defect crystal data. Clusters containing more than 10-13 interstitials were found to take the form of two-dimensional platelets whereas the smaller clusters had a three-dimensional nature. The most stable 2D and 3D configurations were always those which preserved the closest packing.
