Objectives: modeling of phase equilibria and thermodynamic properties of the phases of the Fe–Ti–Zr system within the framework of the CALPHAD method; development of the database of parameters of models of thermodynamic properties of solid solutions of five-component systems Fe–Cu–Ni–Ti–Zr and Fe–Cu–Ni–Ti–Hf; calculations within the framework of the CALPHAD method of metastable phase transformations with the participation of supercooled melts of the Fe–Cu–Ni–Ti–Zr and Fe–Cu–Ni–Ti–Hf systems; theoretical analysis and generalization of results of investigations, determination of fundamental factors influencing the amorphization of liquid alloys. Research methods: modeling of thermodynamic properties of phases in the framework of mathematical models and models of associated solution, CALPHAD-method for calculations of phase equilibria. Results: a new thermodynamic assessment of the Fe–Ti–Zr system was developed, and calculated isothermal and polythermal sections, projections of liquidus and solidus surfaces of the phase diagram, coordinates of nonvariant transformations, reaction scheme of the Fe–Ti–Zr system; database for modeling the thermodynamic properties of liquid alloys and solid solutions of five-component Fe–Cu–Ni–Ti–Zr and Fe–Cu–Ni–Ti–Hf systems were developed; concentration regions for the production of rapidly quenched amorphous alloys of Fe–Ni–Ti, Fe–Ni–Zr, Fe–Ni–Hf, Fe–Ti–Zr, four- and five-component Fe–Cu–Ni–Ti–Zr and Fe–Cu−Ni−Ti−Hf systems were predicted; fundamental factors influencing the amorphization of melts of the studied systems are determined. Range of application: investigations in the field of physicochemical theory of liquid alloys and phase equilibria; development of new technologies for the synthesis of amorphous and high entropy alloys; research and development in the field of chemical and physical materials science.  Product Description popup.authors Agraval Pavlo G.
