WebMar 12, 2024 · A self-interstitial is an atom in crystal placed into an interstitial site. For metals this kind of defect is quite rare, because the size of the atom of the metal is much bigger then interstitials, and it causes bigger deformations of the crystalline lattice. Types of vacancies and self-interstitials are presented below. Figure 2. WebMay 30, 2024 · Single self-interstitial atom (SIA) configurations and clusters. The clusters are small (size 2–4) C15 Laves clusters ... Short-range structures for interatomic repulsion, where one interstitial atom is placed randomly in the bcc crystal without relaxation (so that it is relatively close, but not too close, to its neighbour atoms). ...
