This paper tries to predict diffusion coefficients of impurity atoms in copper and silver from the basic properties of the solute atoms. For this purpose a multiple regression analysis was made on the diffusion data selected from the JST Diffusion Database. The coefficients of determination (R2) for the activation energy of diffusion were 0.71 for Cu solvent and 0.92 for Ag solvent, and those for the frequency factor were 0.27 and 0.77 for Cu and Ag solvents, respectively. The position in the periodic table and the electronegativity of solute atoms were found to be highly significant independent variables. The present model shows an ability comparable to Le Claire’s electrostatic model in prediction of the activation energies for impurity diffusion in Cu and Ag.
