Assessment of substitutional self-diffusion along short-circuit paths in Al, Fe and Ni

The kinetics of self-diffusion along grain boundaries and dislocations (pipe diffusion) is analyzed in Al, α- and γ-Fe and Ni. The available experimental information is critically reviewed. The suggested values given in the present work are assessed with focus on consistency and applicability to thermo-kinetic simulation. The proposed data are evaluated between room temperature and the melting point.
