Abstract
Enrichment of Cr on both <100> and ½<111> dislocation loops has been reported under ion, electron and neutron irradiation in Fe-xCr with x=9-15 at.%. Cr enrichment in Fe-9,12Cr around edge of loops is predicted by atomistic Monte Carlo simulations. MC simulations indicate that Cr clustering on loops disappears above equilibrium solubility limit (ΔT~100-150K). MD simulations indicate that Cr enrichment at loops enhances their strength in a range of specific loading conditions.
