Abstract

The mixing enthalpies of liquid binary In–Ni alloys (0.85 < xNi < 1) at 1800 K were determined by isoperibol calorimetry. The thermodynamic properties of the In–Ni liquid binary alloys were calculated for the entire composition range using the model of ideal associated solutions. The thermodynamic activities of melt components show negative deviations from the ideal behavior. The mixing enthalpies are characterized by moderate exothermic effects. The minimum mixing enthalpy of melts is –12.0 ± 0.1 kJ/mol at xNi = 0.59.
