摘要

It is shown that the dependence of self-interstitial cluster diffusivity in Fe-Cr alloys on Cr concentration correlates with that of swelling in these alloys under neutron irradiation; namely, with increasing chromium concentration the cluster diffusivity first decreases and then increases. The origin of such behaviour lies in a relatively long-ranged, approx 1 nm, attractive interaction between Cr atoms and crowdions. The minimum diffusivity is realized for approx 11 at. percent Cr, where all crowdions constituting the cluster interact with Cr atoms, but the interaction fields of different Cr atoms do not overlap.
