Abstract

The partial and integral mixing enthalpies of Fe-Sc melts are determined by calorime-tryat 1873 К over the entire composition range. It is established that the minimum enthalpy of mixing is -12.4 ±0.6 at х = 0.46 and the first partial enthalpies of mixing are


3.8 (kJ/mole). Thermodynamic properties of the Fe-Sc melts are calculated by the model of ideal associated solutions. It is found that the activities of components have negative deviations from parameters of ideal solutions.
