Abstract

It is shown that a minimum derivation of the recently published unified equation for the temperature dependence of the self-diffusion coefficient in liquid metals can be also obtained from the similarity of interatomic potentials, using dimensional analysis. This relation is extended for the determination of the pressure and composition dependence of the self-diffusion coefficients by the use of pressure and composition dependent scaling parameters (melting point, atomic volume and mass).
