摘要

The interaction of interstitial carbon with substitutional silicon and the effect of this interaction on the diffusion of carbon within body-centered-cubic iron, are computed using electronic density-functional theory. Both the activation energy for diffusion and the diffusion prefactor are predicted. Good agreement is found for those cases where a comparison with experimental data is possible.
