WebFeb 1, 1978 · Production of self-interstitial atoms There are three basic mechanisms for the produc- tion of SIAs: irradiation with energetic particles (such as MeV-electrons, protons or neutrons); plastic defor- mation; and the production of SIAs in thermal equi- librium at high temperatures. In this section only the non-equilibrium techniques are discussed. WebVacancies and Self-Interstitials - Volume 16 Issue 11. ... This article aims to review in rather cursory fashion the ways the concepts of lattice defects have contributed at an early stage to our understanding of solid-state kinetics in metals and insulators.
