Structural features and strength behavior of TRIP/TWIP steels
D. V. Prosvirnin, M. S. Larionov, S. V. Pivovarchik, A. G. Kolmakov
A review of the literature data on the structural features of TRIP / TWIP steels, their relationship with mechanical properties and the relationship of strength parameters under static and cyclic loading was carried out. It is shown that the level of mechanical properties of such steels is determined by the chemical composition and processing technology (thermal and thermomechanical processing, hot and cold pressure treatment), aimed at achieving a favorable phase composition. At the atomic level, the most important factor is stacking fault energy, the level of which will be decisive in the formation of austenite twins and / or the formation of strain martensite. By selecting the chemical composition, it is possible to set the stacking fault energy corresponding to the necessary mechanical characteristics. In the case of cyclic loads, an important role is played by the strain rate and the maximum load during testing. So at high loading rates and a load approaching the yield strength under tension, the intensity of the twinning processes and the formation of martensite increases. It is shown that one of the relevant ways to further increase of the structural and functional properties of TRIP and TWIP steels is the creation of composite materials on their basis. At present, surface modification and coating, especially by ion-vacuum methods, can be considered the most promising direction for the creation of such composites.
Keywords: TRIP steels, TWIP steels, mechanical properties, stacking fault energy, composite materials, coatings.

Microstructure and corrosion resistance of Mo – 15 at. % Si – REE (Sc, Nd) alloys in air
and vapor-air medium
L. Yu. Udoeva, R. I. Gulyaeva, A. V. Larionov, S. N. Agafonov, S. N. Tyushnyakov
The research results of the REEs effect, in particular, Sc and Nd, on the structural-phase state and behavior of a high-temperature Mo – Si composite with a hypereutectic composition, which crystallizes from the melt with the formation of a two-phase natural (in situ) composite during oxidation in dry and moist air were presented. Samples of model alloys with different REE concentrations were obtained by vacuum-arc melting of a mixture consisting of the Mo – 15 Si (at. %) binary alloy and additives of alloying elements. Phase composition, microstructure features and distribution pattern of alloying components in Mo – Mo3Si metal-silicide composites containing from 0,5 to 3,0 at. % Sc or Nd were identified by X-ray diffraction and electron microscopy. Corrosion resistance of Mo – 15 at. % Si – REE (Sc, Nd) alloys during continuous heating to 700 and 850 °C in air and in a vapor-air medium was evaluated by thermal analysis methods (DSC and DTA). It was shown that microalloying of the Mo – 15 at. % Si with scandium or neodymium within 0,5 at. % leads to decrease in the oxidation rate when heated in air to 850 °C. Increasing the concentration of alloying elements to 3,0 at. % REE during oxidation in air adversely affects the corrosion resistance of samples, moreover the oxidation of alloys with neodymium proceeds at a higher rate than with scandium. During non-isothermal heating in a vapor-air medium, the alloy doped with scandium oxidizes more slowly than the binary one, and the sample with neodymium, by way of contrast, oxidizes at a much higher rate compared to dry air.
Keywords: molybdenum-silicon alloys, alloying, scandium, neodymium, microstructure, corrosion, air, water vapor.

N. R. Memetov, A. V. Gerasimova, A. E. Kucherova
The paper evaluates the effectiveness of the use of graphene nanostructures in the purification of lead (II) ions to improve the ecological situation of water bodies. The mechanisms and characteristic parameters of the adsorption process were analyzed using empirical models of isotherms at temperatures of 298, 303, 313 and 323 K, which correspond to the following order (based on the correlation coefficient): Langmuir (0.99) > Temkin (0.97) > Dubinin – Radushkevich (0.90). The maximum adsorption capacity of the material corresponds to the range from 230 to 260 mg/g. We research the equilibrium at the level of thermodynamic parameter estimates, which indicates the spontaneity of the process, the endothermic nature and structure change of graphene modified with phenol-formaldehyde resin during the adsorption of lead (II) ions, leading to an increase in the disorder of the system.
Keywords:adsorption; graphene nanostructures; isotherms; heavy metals; water treatment, lead ions.

The influence of lattice and shell type architecture on the mechanical properties of biodegradable polymer scaffolds designed to create structures for bone tissue engineering is investigated. Varying the topology of nodal connections allows you to control the relative rigidity of the metamaterial in the range from 0.004 to 0.123. The possibility of creating permeable scaffolds using thermally extruded 3D printing based on polymers of different elasticities - polylactide and polyurethane is shown. The use of “unit cells” of various types makes it possible to fabricate structures such as shells based on polylactide with a compressive strength of 1.5 to 19.7 MPa. Shells with a cubic type architecture based on polyurethane can be almost reversibly deformed at values of technical deformation of more than 50 %. The developed approaches for obtaining polymer metamaterials and modifying their surface with calcium phosphate layer using an artificial interstitial fluid can increase the hydrophilicity of materials.
Keywords: bone tissue regeneration, scaffold, metamaterials, trusses, periodical surfaces, 3D printing, polylactide, polyurethane, calcium phosphate coating, hydrophilization.

Properties of nanocomposites based on isotactic polypropylene and high-pressure polyethylene with metal-containing nanofillers
N. I. Kurbanova, T. M. Gulieva, N. Ya. Ischenko
The effect of additives of nanofillers (NF) containing nanoparticles (NP) of copper oxide, stabilized by a polymer matrix of maleized polyethylene (MPE), obtained by the mechanochemical method, on the properties of composites based on isotactic polypropylene (PP) and high-pressure polyethylene (PE) was studied by X-ray phase (XRD) and thermogravimetric (TGA) analyzes. The enhancement of strength, deformation, and rheological parameters, as well as the thermo-oxidative stability of the obtained nanocomposites was revealed, which, apparently, is due to the synergistic effect of the interaction of copper-containing nanoparticles with anhydride groups of MPE. It is shown that nanocomposites based on PP/PE/NF can be processed both by pressing and injection molding and extrusion, which expands the scope of its application.
Keywords: isotactic polypropylene (PP); polyethylene (PE); copper-containing nanofillers; maleized polyethylene (MPE); physical-mechanical properties; XRD, TGA analyzes.

TiC plasma spray cermets
V. I. Kalita, A. A. Radyuk, D. I. Komlev, A. B. Mikhailova,
A. V. Alpatov, D. D. Titov, M. I. Alymov
The microstructure and microhardness of eleven volumetric cermets based on TiC carbide with nickel and cobalt based matrices after liquid-phase sintering at a temperature of 1400 °C were studied. It is supposed to use the research results for the subsequent formation of a powder for plasma spraying of coatings. The compositions of the matrix, additional hardening phases, and carbon were selected taking into account the specific features of the formation of plasma coatings: a decrease in the carbon content and high solidification rates of the sprayed particles with the formation of additional nanosized carbides and an increase in the volume fraction of carbides from 70 % to 88 %. As the matrix, we used the traditional composition for cermets with TiC carbide, NiCr – Mo, and industrial powders, PGSR brands, Ni – 13.5 Cr – 2.7 Si – 4.5 Fe – 0.37 C – 1.65 B, and TAFA 1241F Co – 32 Ni – 21 Cr – 8 Al – 0.5 Y. The ring zone on TiC carbide is formed with the participation of WC, Cr3C2, TiN, matrix phases and additional carbon in the composition of cermets, 1 – 2.8 %, as a result, the initial volume fraction of TiC carbide increases 70 to 88 %. Additional carbon is consumed to reduce oxygen content at the stage of sintering (reduction of oxides). After sintering, cermets have high microhardness values at a load on an indenter of 20 G, 1940 – 3210 kgf/mm2, and lower values at a load on an indenter of 200 G, which was explained by a scale factor. The maximum calculated contribution of the hardness of the hardening phases to the hardness of the cermet was established for cermets with a Co matrix of 3681 kgf/mm2.
Keywords: bulk cermets, TiC, WC, Cr3C2 and TiN, a matrix based on nickel, cobalt, hardness, carbon, nitrogen, oxygen content.

Highly dispersed catalysts MnOx-CeO2 and MnOx – ZrO2 – CeO2 were synthesized for the oxidation of carbon monoxide. Using XRD and XRF methods, the formation of Mn – Ce – O and Mn – Zr – Ce – O solid solutions, as well as the presence of Mn2O3 and Mn3O4, was established. The specific surface area of the synthesized materials is 121 and 155 m2/g, respectively, with a particle size of 8-10 nm. Deconvolution of XPS spectra was carried out, the relative content of ionic forms of Mn, lattice oxygen Оα and high-energy forms Оβ was determined. When studying the thermal stability of the catalysts, it was found that bicomponent systems have low thermal stability, which leads to an enlargement of particle sizes to 32 nm, a decrease in the specific surface to 29 m2/g, and, as a consequence, to a decrease in catalytic activity. While for MnOx – ZrO2– CeO2, less significant changes are observed: the particle size is 27 nm, the specific surface is 43 m2/g, while the catalytic activity is higher than for MnOx – CeO2. The study of the state of the components of the surface layer of the catalysts after isothermal exposure allowed to ascertain changes in the content of the ionic forms Mn, Oα, and Oβ. Based on the studies, it can be concluded that it is advisable to dope the bicomponent systems MnOx– CeO2 with Zr4+ ions. The resulting solid solution ZrO2– MnOx – CeO2 is more stable under the influence of high temperatures.
