A calorimetric study and modeling of the enthalpy of mixing of Cu-Fe-V melts

The partial enthalpy of mixing of vanadium in three-component Cu-Fe-V melts was studied at 1873 K along sections with constant x _Cu/x _Fe ratios of 3, 1, and 1/3 over the composition range x _V = 0–0.55 by high-temperature isoperibolic calorimetry. The Muggianu-Redlich-Kister model was used to describe the concentration dependence of the integral enthalpy of mixing of Cu-Fe-V melts over the whole concentration triangle. The contribution of ternary interaction to the integral enthalpy of mixing of Cu-Fe-V melts was calculated.
