Abstract

Calculated concentration dependences of interdiffusion coefficients and coefficients determining contributions of initial and boundary conditions for various alloy components into distribution of concentrations in the diffusion zone are illustrated. The analysis of these dependences shows that kinetics of component redistribution is determined by the component that diffuses slowly, which distinguishes the results of this approach from that of the generalized theories of the Darken approach.

三元合金中的相互扩散理论：动力学相关系数的浓度依赖性

摘要

说明了计算的相互扩散系数的浓度依赖性和确定各种合金成分的初始和边界条件对扩散区浓度分布的贡献的系数。对这些依赖关系的分析表明，组分重新分布的动力学是由缓慢扩散的组分决定的，这将这种方法的结果与 Darken 方法的广义理论的结果区分开来。
