The mixing enthalpies of liquid ternary Al–La–Ni alloys are determined by isoperibol calorimetry for sections (Al0.42La0.58)1–xNix (0 < x < 0.27) at 1430 K and (La0.25Ni0.75)1–xAlx at 1770 K (0 < < xAl < 0.3) or 1800 K (0.3 < xAl < 0.39). The experimental mixing enthalpies and those calculated with the Redlich–Kister model are characterized by exothermic effects. The minimum mixing enthalpy of the melts is –54 kJ/mol for composition Al0.4La0.2Ni0.4.
