The mixing enthalpies of liquid Cu-Fe-(Cr, Co, Ni) alloys were studied at 1873 K by the high-temperature isoperibolic calorimetry for the first time. The phase relations in Cu-Fe-Cr alloys were investigated using the methods of the physical-chemical analysis. The new thermodynamic assessments of the binary Fe-Co and ternary systems were carried out in the spirit of the CALPHAD-method.The composition ranges of the manufacturing of the alloys with special structures and temperature-composition limits of the formation of the supersaturated solid solutions during the liquid quenching were assessed. The analysis of the temperature-composition dependence of the thermodynamic mixing functions was carried out.
