Abstract

The molecular dynamics method has been used to simulate displacement cascades created by primary knock-on atoms (PKAs) with energies EPKA= 5, 10, 15, and 20 keV in aluminum at temperatures T = 100, 300, and 600 K. A series of 24 cascades was simulated for each pair of the parameters (EPKA, T) to ensure a representative sampling. The number of Frenkel pairs, the fraction of vacancies (εvac) and self-interstitial atoms (SIA) (εSIA) in point defect clusters, the average yield of vacancy (Yvac) and SIA (YSIA) clusters per cascade, and the average relaxation time τc have been determined as a function of (EPKA, T). It has been shown that displacement cascades of in aluminum decompose into several sub-cascades along PKA trajectory. Such a spatial structure of cascades is responsible for the absence of the dependence of the values of 〈εvac〉, 〈εSIA〉, 〈Nvac〉, 〈NSIA〉, and τc on the energy of PKAs.
