AbstractThis work concerns a study of mechanical characteristics (strength and elasticity) of the Ті92.5Nb5Mo2.5 ternary alloy under cyclic tensile loading, as well as the effect of this test on a phase transformation of orthorhombic martensite which was the initial structure. Young’s modulus was calculated under loading (44 ≤ El ≤ 55 GPa) and unlo...

The effect of the epitaxial-layer thickness on the temperature of various samples of heterostructures with significantly different absorption coefficients as a result of its radiation heating is studied. It is shown that the beginning of growth of the epitaxial layer is accompanied by an abrupt increase in temperature, which is caused by growth in ...

The domain structure on the surface of 2-methylbenzimidazole (MBI) crystals is studied using various modes of atomic-force microscopy, which made it possible to visualize the surface potential distribution. MBI crystals are grown by evaporation from a saturated ethanol solution. Using the scanning Kelvin probe microscopy mode, the potential distrib...

Abstract—This article discusses a promising method for improving the tribological properties of the surface of structural high alloy steel with ultrafine grain structure by low temperature ion nitriding in multicomponent low-pressure glow discharge plasma. The effect of treatment by intense plastic torsion deformation on the structure and mechanica...

AbstractThe magnetic structure of composition-modulated Dy/Co films is investigated by a combination of vibrating sample magnetometry (VSM), magnetic force microscopy, and polarized neutron reflectometry at room temperature. Perpendicular magnetic anisotropy in the superlattices is shown to be due to the perpendicular orientation of magnetic moment...

Abstract—The influence of the processing of scanning electron microscope (SEM) images on its calibration using test objects with a trapezoidal profile and large inclination angles of the side walls is considered. The influence of different methods of the linearization of SEM signals on the calibration accuracy is shown. Two methods of SEM calibrati...

Abstract—The interaction potentials of charged particles with charged planes and axes in ionic crystals with the NaCl-type structure (in particular, in crystals of sodium, potassium, and rubidium halogenides) are calculated at a temperature of Т = 300 K. Moliere approximations are used in one-particle potentials of positively and negatively charged...

AbstractIn this paper, we develop a new technique for quantitative analysis of the near region of X-ray absorption spectra that is based on the extraction of spectrum descriptors and machine learning. The use of descriptors (edge position, intensity and curvature of minima and maxima, and tangent of the slope of the absorption edge) allows solution...

AbstractThe possibility of analyzing deposited metal catalysts by small-angle neutron scattering through contrast variation based on the use of H2O/D2O mixtures is shown. The use of the contrasting technique makes it possible to selectively obtain the size distribution of metal particles in a wide range of sizes. The reliability of the obtained siz...

AbstractMg nanofilms 1–2 nm thick are obtained on a MgO/Mg surface by bombardment with Ar+ ions. It is shown that to obtain homogeneous Mg films, the most optimal modes of ion implantation are: energy of E0 = 1–5 keV, dose of D = 8 × 1016 cm–2, and an angle of ion incidence of α = 0°–10° relative to the normal. The composition, electronic structure...
