The mixing enthalpies of glass-forming Fe-Ni-Ti, Fe-Ni-Zr, and Fe-Ni-Hf liquid alloys were investigated at 1873 K by high-temperature calorimetry. The thermodynamic properties of melts in the Fe-Ni-Hf system were studied for the first time. Along the studied sections (x(Fe)/x(Ni) = 0.50/0.50 at x(Ti) = 0-0.15, x(Fe)/x(Ni) = 0.50/0.50 at x(Zr) = 0-0.45, x(Fe)/x(Ni) = 0.75/0.25 at x(Hf) = 0-0.18, x(Fe)/x(Ni) = 0.50/0.50 at x(Hf) = 0-0.45, and x(Fe)/x(Ni) = 0.25/0.75 at x(Hf) = 0-0.46), the partial mixing enthalpies of IVB metals and the integral mixing enthalpy showed negative values. New experimental data on the integral mixing enthalpy of the liquid alloys were combined with the literature data, and the increment H-m isotherms of the ternary Fe-Ni-Ti, Fe-Ni-Zr, and Fe-Ni-Hf liquid alloys at 1873 K were plotted using the Redlich-Kister-Muggianu equation. The increment H-m function was negative in each of the studied systems, being indicative of strong interparticle interaction of the components in the glass-forming liquid alloys. The composition dependence of the integral mixing enthalpy of the liquid alloys and its change in the series of the systems can be qualitatively interpreted in terms of the electronegativity of the chemical elements in the liquid alloys.
