The effect of alloying elements on the solubility of Cu in solid Fe has been investigated by using solid-liquid diffusion couples. An addition of Co, Ni, and Al results in an increase of the solubility of Cu, while that of V, Cr, Mn, Si, and Sn decreases the solubility. Thermodynamic calculation of the solid/liquid phase equilibria in the Fe-Cu-X ternary system has been also performed, where a set of thermodynamic parameters of solid and liquid phases has been evaluated. Furthermore, the equation that describes the change of the solubility of Cu in solid Fe with an addition of alloying elements has been derived by thermodynamic analysis of these experimental values.
