摘要：
The mixing enthalpies of liquid ternary Al-La-Ni alloys are determined by isoperibol calorimetry for sections (Al0.42La0.58)(1-x)Nix (0 < x < 0.27) at 1430 K and (La0.25Ni0.75)(1-x)Al-x at 1770 K (0 < < x(Al) < 0.3) or 1800 K (0.3 < x(Al) < 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.
