Simulation of atomic displacement cascades in binary Fe-9`a`o. %Cr alloy by molecular dynamics method

This paper is devoted to the results of computer simulation of primary irradiation damage processes in Fe-9ат.%Cr by molecular dynamics method. Simulation is performed for temperature of 300 K. N-body interatomic potentials are used here. Cascade energies in rang of 0.1 – 20 keV are considered. Evaluations of amounts of defects survived in displacement cascades as well as numbers and sizes of vacancy and self-interstitial atoms (SIAs) are obtained. It is revealed that Cr fraction in SIAs is more than twice as higher in comparison with Cr fraction in initial alloy.
