Resumo
The purpose of this work is to investigate the formation thermodynamics and migration properties of self-interstitials in Al and Ni at high temperatures. The relative stability of these defects is compared to that of vacancies and divacancies, which are the defects usually considered to explain defect concentration and self-diffusion plots. The contribution of interstitials is analyzed in terms of the upward curvature that most fcc metals exhibit for the self-diffusion plots in the high temperature range.
