Study of the primary radiation damage in the binary FeCr alloy

This paper is devoted to the results of the molecular dynamics simulation of primary radiation damage disordered binary alloys: Fe-5at.%Cr, Fe-10at.%Cr and Fe-14at.%Cr. Simulation is carried out at 300 K using many-body interatomic potential. We examined cascades of atomic displacements cascades for the energies of primary knock-on atom 20 keV. On the results of the simulation was estimated number of "surviving" point defects, survived recombination in the cascade, and the results on the composition of clusters of vacancies and self-interstitial atoms formed in such cascades.
