Objectives: modeling of phase transformations and thermodynamic properties of phases; determination of the regularities of the change in the thermodynamic properties of the melts in the range of the investigated systems; determination of causes and factors influencing the formation of amorphous and crystalline high-endurance alloys (HEA); calculation of phase transformations and thermodynamic properties of phases of Cu-Ni-Ti-Zr-Hf and Co-Cr-Cu-Fe-Ni systems and prediction of technological conditions for the production of amorphous and crystalline HEA. Research methods: the model of the associated solution for modeling the temperature-concentration dependence of the thermodynamic properties of the melts; CALPHAD method for calculating stable and metastable phase transformations and thermodynamic properties of phase systems. Results: new experimental data on the thermodynamic properties of the melts of glass forming systems; models of thermodynamic properties of phases of Co-Cr-Cu-Fe-Ni and Cu-Ni-Ti-Zr-Hf systems have been developed; diagrams of equilibrium and metastable phase transformations of equiatomic alloys of Co-Cr-Cu-Fe-Ni and Cu-Ni-Ti-Zr-Hf systems are calculated; the factors pointing to the possibility of formation of amorphous and crystalline HEA are determined; developed databases that can be used to predict the concentration ranges of amorphization of metal melts and production of HEA. Range of application: fine metallurgical synthesis; material science; development of the new technologies for the synthesis of HEA; research and development in the field of natural and technical sciences.
