Abstract

The simulation of atomic displacement cascades generated by radiation in iron-chromium alloys on the basis of the molecular dynamics simulation is carried out. Atomic displacement cascades are generated by primary knock-on atoms with the energy up to 20 keV. The main characteristics of atomic displacement cascades (the number of formed defects, cascade efficiency, durations of the main stages, and the size of the radiation-damaged region) in iron-chromium alloy for different primary knock-on atom energies are calculated. The size and spatial distribution of survived point defect clusters formed by atomic displacement cascades are analyzed.
