Abstract
We have performed molecular dynamics simulations of self-interstitial atom diffusion in pure alpha -Fe and in a dilute Fe-1.0-at. % Cu alloy. We find that the presence of this oversized substitutional solute significantly alt ers the self-interstitial diffusion properties. We explain this through a m echanism directly based on the atomic strain field interactions between the Cu and the self-interstitial atom.
