根据我们的实验数据[13]，在1000°C下，在Cu-Fe-Ni系统中确定了该系统六个扩散偶中组分浓度分布的常规和有效互扩散系数。应用这些系数来解释三元体系中的相互扩散的特殊功能的可能性进行了分析。结果表明，有效互扩散系数与体系的热力学特性有一定的相关性。
Conventional and effective interdiffusion coefficients have been determined in a Cu-Fe-Ni system for 1000°C based on our experimental data [13] on the distribution of concentrations of components in six diffusion couples of this system. The possibilities of applying these coefficients to interpret peculiar features of interdiffusion in ternary systems are analyzed. It has been demonstrated that effective interdiffusion coefficients are in a certain correlation with thermodynamic characteristics of the system.
