Displacement cascades in random Fe-Cr binary alloys with a
widerangeofCrconcentrationfrom2%to20%weresimulated
by using the molecular dynamics method and the effect of Cr
concentration on cascade damage was carefully investigated.
The results showed that the average number of surviving Frankel
pairs is approximately the same in Fe-Cr alloys and the average
fraction of vacancies in clusters is roughly constant, within
scatter, over the whole range of Cr concentration. The average
fraction of self-interstitial atoms (SIAs) is slightly bigger in a
lower Cr concentration alloy than in a higher Cr concentration
alloy. The number of Cr atoms associated with survived self-
interstitial defects was analyzed. The data show that the content
of Cr in interstitials approximately exceeds two or three times
the matrix content, which indicated that there is a significant
enrichment of SIA defects by Cr.
