Welding of high-nitrogen austenitic steels (Review)
V. S. Kostina, M. V. Kostina
Alloying with nitrogen allows one to substantially increase the strength of steels, especially of the austenitic steels, in which the equilibrium nitrogen content can reach 0.4 – 0.7 wt % depending on their chemical composition. Nitrogen stabilizes austenite and enhances its corrosion and wear resistance. For this reason, nitrogen-containing austenitic steels are advantageous structural materials, in particular, for heavy loaded welded structures. However, wrong choice of the welding method, regime, or filler for high-nitrogen steels can cause critical defects such as pores and cracks in the welded joints and substantially decrease their mechanical properties and corrosion resistance compared to those of the base metal. More than hundred literature sources have been considered for the analysis of welding types and methods for austenitic steels containing ≥ 0.4 wt. % nitrogen, the criteria for their weldability, and the causes for potential negative phenomena occurring upon their welding. For such steels, information is provided on the welding filler materials as well as on the modes and parameters of the welding process (supplied heat, presence/absence of a protective atmosphere, its composition, etc.). The structure, phase composition, and properties of the resulting welded joints are considered. The examples are given on the effect of the subsequent processing of welded joints (heat treatment and thermal deformation processing for the elimination of the resulting distortion) on their basic properties.
Keywords: welding; high nitrogen stainless steel; weld defects; filler metal; corrosion resistance; mechanical properties.

Features of the defect structure and photoluminescence
of nominally pure LiNbO3 crystals grown
from boron doped charge
N. V. Sidorov, A. V. Kadetova, M. V. Smirnov, R. A. Titov,
N. A. Teplyakova, M. N. Palatnikov
Features of the defect structure of nominally pure LiNbO3:В crystals were investigated by X-ray diffraction analysis and photoluminescence. Crystals were grown by the Czochralski from a mixture of congruent composition charge containing 0.08 and 0.12 wt. % boron. At this, the concentration of boron in crystals is at the level of trace amounts of metallic impurities and is ~ 10–4 wt%. MeO6oxygen-octahedral clusters are responsible for the ferroelectric and nonlinear optical properties of the crystal. It has been found that in LiNbO3:B crystals, the lengths of O–O, Me–O, and Me–Me (Me–Li, Nb) bonds in clusters, the arrangement of Me cations, vacancies, and NbLi point defects along the polar axis differ significantly from those for nominally pure congruent crystal. NbLi defects and transition metals are deep electron traps responsible for the photorefraction effect. The photoluminescence spectra showed that the concentration of defects and metals in the investigated LiNbO3:B crystals is lower than in the congruent crystal. these differences can be due to both a change in the properties of the boron-containing melt and the localization of trace amounts of boron in the O4tetrahedral gaps of the LiNbO3 crystal structure. In the first case, reactive boron binds cations of niobium and transition metals in the melt into stable complexes.
Keywords: lithium niobate single crystal, charge, defects, X-ray diffraction analysis, photoluminescence.

On the prospects of using silicon dioxide
obtained from mineral raw materials
as an enterosorbent
D. V. Mayorov, Yu. O. Velyaev
Samples of amorphous silicon dioxide (SiO2) were obtained by acid decomposition of mineral raw materials (nepheline). Their physico-chemical, acid-base and structural-surface properties have been studied by methods of chemical analysis, Parks, BET, BJH, etc. It was found that in terms of the content of impurities, the pH of the aqueous extract, the pH values of the isoionic point and the zero charge point, the SiO2 samples obtained are almost identical to pyrogenic amorphous silicon dioxide obtained from reactive raw materials (pharmaceutical preparation “Polysorb PM”) and have an increased specific external surface compared to “Polysorb PM” (in 1.1 – 1.9 times) and specific pore volume (1.4 times). Based on the obtained values of the specific capacity of the adsorption monolayer of the surface of SiO2 samples and the change in Gibbs energy (ΔG0) during sorption, it is concluded that the method of their preparation does not significantly affect the physicochemical properties of their surfaces and the mechanism of nitrogen sorption. Based on the results obtained, an assumption is made about the prospects of using silicon dioxide, obtained on the basis of acid processing of mineral raw materials, as an enterosorbent in therapeutic practice.
Keywords:enterosorbents, polysorb, nepheline, amorphous silica, structural-surface and acid-base properties, sorption.

Effect of low-temperature plasma treatment
on polyketon films: changes in the chemical
structure and surface morphology
M. S. Piskarev, А. V. Zinoviev, A. B. Gilman, E. A. Skryleva,
B. R. Senatulin, A. K. Gatin, A. A. Kuznetsov
Using X-ray photoelectron spectroscopy, the change in the chemical composition of the polyketon films surface as a result of treatment by the low-pressure direct current discharge was studied. The films were placed at the anode and cathode, and filtered atmospheric air was used as the working gas. The formation of a significant amount of oxygen-containing groups on the polymer surface was shown. Using atomic force microscopy, it was found that plasma treatment leads to a significant increase in the surface roughness of the films. Such changes improve the contact and adhesion properties of polyketon films.
Keywords:polyketon films, surface modification, direct current discharge, X-ray photoelectron spectroscopy, surface chemical composition, atomic force microscopy, morphology.

The results of dynamic compressive testing of alumina samples with different grain sizes sintered from nano and fine α-Al2O3 powders are presented. The ceramics were obtained by spark plasma sintering (SPS). The effect of heating rate (Vh), sintering temperature (Ts), holding time (ts), cooling rate (Vc) on hardness, fracture toughness, dynamic strength stress (sY) of Al2O3 has been studied. An amorphous layer of nanometer thickness was present on the surface of nanopowders in the initial state. After sintering, the grain boundaries of the ceramics had a crystalline structure; no inclusions of the amorphous phase were found. It has been suggested that during the SPS process, an amorphous structure containing an excess free volume is transformed into a crystalline phase with the formation of dislocation-type defects at the grain boundaries, which create long-range internal stress fields. It is shown that nanopores less than 50 – 100 nm in size are present at the grain boundaries of sintered ceramics. It is shown that the nonmonotonic nature of the dependence of sY on the temperature and time of the SPS is due to the simultaneous change in the density, the nonequilibrium state of the grain boundaries, and the grain size of the ceramic. It is shown that a decrease in the degree of nonequilibrium of the grain boundaries of alumina due to an increase in the SPS temperature or an increase in the holding time makes it possible to increase the dynamic strength of alumina. It has been established that an increase in the cooling rate leads to the formation of compressive residual stresses and a slight increase in sY of ceramics. The maximum dynamic strength (sY = 1755 MPa) for alumina ceramics with average grain size 1.6 – 2 mm obtained by SPS (Vh = 50 °С/min, Ts = 1520 °С, ts = 50 min).
Keywords: Alumina, microstructure, grain boundary, dynamic strength, internal stresses, residual stresses, spark plasma sintering.

Influence of the technological mode of mixing
and curing system on the properties
of compositions based on nitrile rubber
and ultrahigh molecular weight polyethylene
N. V. Shadrinov, A. A. Borisova, A. R. Khaldeeva, K. P. Antoev
The results of a study of the influence of the mixing mode and curing system on the properties of low temperature and oil resistant rubber based on a composition of butadiene-nitrile rubber (BNKS-18AMN) and ultra-high molecular weight polyethylene (GUR 4113) are presented. Different ways of UHMWPE introducing into the rubber compound are considered: mixing before and after the introduction the main ingredients of the rubber compound at temperatures up to 80 °C (below the melting point of UHMWPE) and preliminary high-temperature (160 °C) mixing of rubber and UHMWPE. It was found that the preliminary high temperature mixing of rubber with UHMWPE leads to a decrease in the viscosity of the rubber compound, as well as a reduction in the scorch time and the achievement of an optimum vulcanization but does not lead to significant changes in the physical and mechanical properties and oil resistance of vulcanizates. The study of the influence of the curing system showed the effectiveness of using a combined sulfur-peroxide curing system, which is manifested in the improvement of the technical properties of vulcanizates, which is largely due to an increase in the density of rubber crosslinking through the formation of stronger and more heat-resistant C-C bonds. It has been shown that the best set of technical properties of vulcanizates, including high frost-resistance, physical and mechanical properties, resistance to hydrocarbon environment and retention of properties after thermal exposure, is achieved when using the sulfur-peroxide combination S/DCP – 1/2.
Keywords:nitrile rubber, ultra-high molecular weight polyethylene, mixing mode, curing properties, physical and mechanical properties.
