These data will form a scientific foundation for the development of new alloys for various applications (structural alloys, functional materials with special properties, materials for nuclear energetic) and will allow to formulate criteria for selection of alloys with the predicted level properties and proposals for technologies of their production. popup.description2  Phase equilibria are sudied and phase diagrams of the ternary systems Hf-Rh-Ir, Ni-Sc-Zr, Ti-Fe-Sn, Al-V-Fe, Fe-Co-Ho (Er, Tm), Mo-Co-B and binary systems Co-Ho (Er, Tm, Lu) and Fe-Er (Tm, Lu) are constructed first (or refined) in a wide range of concentrations and temperatures, which are presented in the form of isothermal sections and vertical sections, projections of liquidus and solidus surfaces, melting diagrams and reaction schemes. The hydrogenation processes of the surfaces of the Ni-Sc-Zr system alloys in the region Zr-ZrNi-Sc57Ni43-Sc were studied. For the first time, the nature of the formation of ternary phases, including Heisler and semi-Heisler phases, in the Ti-Fe-Sn system was established. It is shown that the VNb2TaCrMoWВ0.6 alloy coating obtained by electrospark alloying under dynamic load improves the wear resistance of the sample by two times when paired with an Al2O3 indenter, and by 10 times when paired with a VK6 indenter under quasi-static loading. Thermodynamic properties of binary melts Bi-(La, Ce, Pr, Eu, Tm), Pb-Eu (Yb), Eu-Ge, In-Sr and ternary melts Bi-Cu-Eu and Al-Eu-Ge were determined for the first time. A critical analysis of the current state of research and a generalization of literature data on phase equilibria and thermodynamics for ternary systems formed by aluminum with d-metals of groups IV and VI-VIII, as well as multicomponent systems of the corresponding class, was carried out.
