From the Atomic Jump Frequencies to the Phenomenological Transport Coefficients

Abstract

The SCMF theory based on an atomic model of atom‐vacancy exchange frequencies yields general expressions of the phenomenological coefficients Lij of a multi‐component alloy with any crystallographic structure. The limitations and future improvements of the Self‐Consistent Mean‐Field (SCMF) approach are easily related to the statistical approximation of the thermodynamic correlations and to the time‐dependent effective interactions used to describe the kinetic correlations induced by the vacancy diffusion mechanism.
