Thermodynamic assessment of the Cu–Fe–Cr system was undertaken within the framework of the CALPHAD method. A set of self-consistent thermodynamic parameters was obtained taking into account new experimental data on the mixing enthalpy of liquid ternary alloys and literature information on the phase transitions. Isothermal sections, isopleths, projections of the liquidus and solidus surfaces and cupola of stable and metastable immiscibility of liquid alloys were calculated. The magnitudes of supercooling required for metastable immiscibility of liquid phases were estimated.
