A modified 'hole' theory for solute impurity diffusion in liquid metals

摘要

A modified "hole" theory for solute impurity diffusion in liquid metals is presented. The theory calculates an "effective" valence for the solute impurities by assuming that the bulk valences of the solvent and solute metals are those given by the Engel-Brewer theory (one for bcc structures, two for cph structures, and three for fcc structures).
