Karazin popup.description2 Object of researches: deformable industrial aluminum alloys, electrolytic foils of copper, polycrystalline nickel, iron and model iron based alloy, filamentous single crystals of copper, amorphous metal alloys 11ХСР and Ni78Si8B14. The purpose: the determination of physical regularities of the influence of the structural state and phase composition of the studied materials on the peculiarity of the mechanisms of their deformation. The determination of complex of those elementary acts, which activate and control the processes of microplastic, plastic and superplastic deformation. Methods: mechanical tests, measurements of internal friction, mechanical spectroscopy, metallography, X-ray structural analysis, energy-dispersion X-ray microanalysis, fractography, raster electronic microscopy. Results, novelty: the mechanism of grain boundary sliding, with the participation of the liquid phase and the mechanism of formation of fibrous structures in specimens of aluminum alloys with a matrix structure, superplastically deformed in conditions of high-temperature structural superplasticity. Found that the most sensitive to the degree of plastic deformation by tension of the ferromagnetic transition metals and in ferromagnetic alloys is the internal friction in the region of the maximum in the dependence of of damping of the magnetic field. The peculiarities of the influence of scale factor on the mechanical properties of amorphous metallic alloys and fibrous monocrystals. The regularities of the hardening of filamentary crystals of copper, which is carried out due to their doping by impurities are determined. The results can be used to improve and clarify the physical theories of physical representations of microplasticity, ductility, superplasticity and internal friction of crystalline metals and alloys, and metallic amorphous alloys.
