Objectives: generalization of the literature information on the thermodynamic properties of melts and compositions of amorphous alloys of ternary the Fe–Ni–(Ti, Zr, Hf), Fe–Ti–Zr systems and boundary binary systems; experimental study of the thermodynamic properties of the Fe–Ni–(Ti, Zr) melts; modeling the thermodynamic properties and the short range order in the Fe–Ni–(Ti, Zr) melts within the framework of associated solution model; modeling of phase equilibria in Fe–(Ti, Zr, Hf)_ systems using the CALPHAD method. Research methods: high-temperature isoperibolic calorimetry, mathematical and phenomenological models of thermodynamic properties of melts; CALPHAD-method for calculations of phase transformations of systems. Results: literature data on thermodynamic properties of melts and compositions of amorphous alloys of ternary the Fe–Ni–(Ti, Zr, Hf), Fe–Ti–Zr and boundary binary systems; partial and integral enthalpy of mixing of the Fe–Ni–(Ti, Zr) melts; parameters of the mathematical and associate solution models for the Fe–Ni–(Ti, Zr) liquid alloys; the calculated composition of the associated solution and the estimated concentration regions for the production of rapidly quenched amorphous alloys of the Fe–Ni–(Ti, Zr) systems; thermodynamic assessments of the Fe–(Ti, Zr, Hf) systems, and new versions of phase diagrams and calculated invariant equilibrium reactions for them. Range of application: fine metallurgical synthesis; development of new technologies for synthesis of amorphous and high entropy alloys; research and development in the field of materials science.
