     the recently developed arrhenius formula of the modified sutherland equation was first employed to calculate the self- and impurity diffusivities in liquid sn, bi, and pb. the reliability of the calculated results was validated in comparison with the critically reviewed literature data. based on the reliable tracer and chemical diffusivities available in the literature, the atomic mobility parameters in both sn-bi and sn-pb melts were then evaluated by the dictra (diffusion-controlled transformations) software package with the aid of thermodynamic parameters. comprehensive comparisons show that most of the measured and theoretical diffusivities in sn-bi and sn-pb melts can be reasonably reproduced by the currently obtained atomic mobilities. moreover, the atomic mobilities were further verified by comparing the model-predicted concentration profiles and the measured ones in various liquid sn-bi and sn-pb diffusion couples.
