本文首次采用修正的Sutherland方程的Arrhenius公式计算了Sn、Bi、Pb三种金属的自扩散系数和杂质扩散系数。计算结果的可靠性进行了验证，与严格审查的文献数据相比。基于可靠的示踪剂和化学扩散系数在文献中，在两个Sn-Bi和Sn-Pb熔体中的原子迁移率参数，然后评估的DICTRA（扩散控制的TRANSFORMATION）软件包的帮助下的热力学参数。综合比较表明，大部分的测量和理论的扩散系数在锡铋和锡铅熔体可以合理地再现目前获得的原子迁移率。此外，通过比较模型预测的浓度分布和各种液体Sn-Bi和Sn-Pb扩散偶的测量值，进一步验证了原子迁移率。
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.
