摘要：

The partial and integral mixing enthalpies of Fe-Sc melts are determined by calorimetry at 1873 K over the entire composition range. It is established that the minimum enthalpy of mixing is -12.4 +/- 0.6 at x (Sc) = 0.46 and the first partial enthalpies of mixing are and (kJ/mol). Thermodynamic properties of the Fe-Sc melts are calculated with the model of ideal associated solutions. It is found that the activities of components have negative deviations from parameters of ideal solutions.
