Uvarov, Доктор фізико-математичних наук Registration Date 28-01-2026 Organization Institute of Metal Physics. G.V. Kurdyumov of the National Academy of Sciences of Ukraine popup.description1 Investigation the influence of the features of the spatial structure and atomic composition on the electronic structure and physical properties of Heusler alloys. Using the unique capabilities of the developed methods, to establish correlations between the features of the electronic structure, crystal structure and atomic composition of the compounds of complete Heusler alloys. Using the developed methods, which provide more reliable information compared to traditional methods, to obtain information on the distribution of total and partial atomic electron densities in energy bands, charge and spin states in compounds, and magnetic properties of the materials under study. A detailed comparison of experimentally obtained literature data with the results of theoretical quantum mechanical calculations will, on the one hand, contribute to the improvement of theoretical methods and models, and on the other hand, will allow obtaining comprehensive information about the electronic and magnetic structures and physicochemical properties of the materials under study. Investigation the surface layers formed during the frictional interaction of contact pairs in active environments. Using the developed experimental and theoretical methods, to investigate microstructural changes and local redistribution of impurity elements during intensive high-speed plastic deformation of metal microvolumes during the formation of surface friction layers. Investigation the chemical composition and the closest atomic environment of impurity atoms in the structurally disorganized boundary regions of the grains of surface friction layers. To clarify the conditions for the possibility of the emergence of dynamic systems in places of accumulation of impurity atoms that can cause the transition of ultradisperse systems saturated with oxygen and carbon to a quasi-liquid structurally unstable state during the formation of surface friction layers, in which a crystalline amorphous nanostructured material popup.nrat_date 2026-01-28 Close
