Formation of new intermetallic phases
in the Ta – Ni – Al system

A. S. Shchukin, D. Yu. Kovalev, A. E. Sytschev, A. V. Shcherbakov

Peculiarities of structure and phase formation in 5 Ta – 2 Ni – 3 Al intermetallic system were studied in the paper. The TaNiAl, NiAl, Ni2Al3 and Ta phases were found in the alloy produced by self-propagating high-temperature synthesis (SHS). A transition layer with the composition of Ta51Ni20Al29 about 1 – 2 µm thick was formed on the interface between an unreacted Ta particles and TaNiAl phase. Re-melting of the synthesized alloy at a temperature of about 3000°C leads to the formation of three structural components with the following compositions — Ta85Ni7Al8, Ta52Ni20Al28 and Ta53Ni25Al22. X-Ray analysis of the re-melted alloy showed the presence of reflections that do not correspond to any of the known phases in Ta-Ni-Al system. The alloy with a similar composition was synthesized by electro-thermal explosion (ETE) under load. Synthesized alloy has heterogeneous structure and multiphase composition of the surface layer which is similar to the alloy produced by SHS. Central sample region of the sample produced by ETE is similar to the structural and phase composition of the sample melted at temperature of 3000 °C. The obtained data show the possibility of synthesizing in Ta-Ni-Al system various phases with high Ta content (more than 50 at%).

Keywords: intermetallic, tantalum, Ta – Ni – Al, self-propagating high-temperature synthesis, SHS.

The results of transmission and reflection spectra recording by spectrophotometry were used to study the peculiarities of estimating the optical band gap for Ge2Sb2Te5 thin films after annealing at different temperatures, in particular, in the phase transition temperature range. A significant influence of the spectrum processing algorithms on the obtained results was shown. A comparison of experimental data showed that the surface resistivity, reflection coefficient and optical band gap have different temperature ranges of variation during the crystallization process. In particular, changes of the electrophysical properties continue after the completion of the modification of optical characteristics, which indicates on the two-stage nature of the crystallization process in the Ge2Sb2Te5 films.

Keywords: phase change memory (PCM), chalcogenides, Ge2Sb2Te5 (GST225), thermal annealing, spectrophotometry, optical properties, Tauc method, optical band gap.

Zh. A. Sentyurina, P. S. Dzhumaev

Investigated properties of stainless steel grade GP1, obtained by additive technology (AT) by the method of selective laser melting (SLM) in relation to the operating conditions of liquid metal heat-exchange systems of power plants (vacuum density, corrosion effect of eutectic sodium and potassium alloy Na – K at temperature 700 ± 5 °С). The microstructure of GP1 steel has a fine structure with a characteristic size of structural components from 2 to 3 microns. The results of local chemical analysis of the identified structural components of the material showed a high degree of material homogeneity. The material is sealed, the flow of helium into the sample made by AT was no more than 4·10–10 (Pa·m3)/s. Under the conditions of the tests performed, the corrosive effect of Na – K on the material is observed in the surface layers with a thickness of no more than 2 microns. The corrosion rate of the test material under test conditions was less than 0,01 mm/year, which, according to the existing classification of corrosion resistance, makes it possible to assign the test material under test conditions to the resistance group — very persistent. The results give grounds to continue research on a larger time base and in conditions close to the operating conditions of the heat-exchange systems of power plants (non-isothermal dynamic conditions), as well as to conduct research on other steels obtained by AT, for example, chromium-nickel corrosion-resistant steel of austenitic class with a high level corrosion resistance in the environment of the liquid metal coolant Na – K of eutectic composition.

Key words: additive technology, selective laser melting, stainless steel, microstructure, vacuum impermeability, eutectic sodium and potassium alloy.

The optimization of the synthesis conditions of ultra dispersed silver particles in the extract of hemp fiber

N. S. Dyimnikova, E. V. Erohina, A. P. Moryganov,
S. V. Grigorev, O. Yu. Kuznetsov

The impact of extraction conditions of natural admixtures (pectin compounds, hemicellulose and lignin) from hemp fiber has been evaluated in the process of chemical modification of fibrous mass. It was concluded, that for the maximum extraction admixtures the rise of temperature of fiber’s treatment up to 100 °С is required, and hydroxide natrium up to 10 g/l as well. It was proved by infrared spectroscopy and potentiometric titration methods that the raise of alkalinity boiling liquor leads to the rise of the number of admixtures in the liquor, to the destruction of admixtures as well. But the complex of reducing ingredients that has been formed in the liquor, plays a role as silver ion restorer even under conditions of low temperatures of extraction. The kinetics of silver ions restoration in extract liquor has been evaluated. The correlation of the effectivity of the restoration process of silver ions and number of admixtures in liquor was detected. The restoration in the liquor, that has been obtained under high alkalinity, leads to small sized particles formation (less 30 nm) that was proved by the photon correlation spectroscopy. It was proved that the antimicrobial activity against a test-cultures of the synthesized sols and cellulosic materials treated with the soles depends on the conditions of the synthesis.

 

Keywords: hemp fiber, extraction, natural admixtures, redox potential, synthesis, silver nanoparticles, antimicrobial activity.

Physical and mechanical properties of pyro-compacted
 carbon-carbon material on a woven basis

G. E. Mostovoy, A. A. Konyushenkov

The work showed that a change in the length of the samples within 60 – 100 mm and a width within 12 – 25 mm, as well as the shape of the samples did not have a significant effect on the change in the mechanical characteristics when tested in compression in both directions of the UPA-4 material obtained by deposition pyrocarbon from the gas phase on the basis of graphite viscose fabric URAL-T-22. The carbon matrix of this material was formed as a result of the gradual deposition of pyrolytic carbon from the gas phase at a temperature of 980 °C for ~ 150 hours and at 1070 °C for ~ 100 hours. The paper presents the results of tests at different temperatures. Tests of flat specimens for bending, compressing, and stretching were performed at room temperature. To assess the heat resistance of the material, samples were tested for bending in a neutral argon medium at a speed of active capture 5 mm/min in a temperature range of 20 – 2800 °C. The tests have shown that the developed material is structural and heat-resistant, since in the temperature range up to 2200 °C it retains its bending strength, and as the temperature rises to
2500 °C, it deforms with plasticity without breaking.

Surface physicochemical treatment of nickel foam
for increasing its electrocatalytic activity
in overall water splitting

D. V. Fominski, V. N. Nevolin, R. I. Romanov, V. Yu. Fominski,
 O. V. Komleva, P. F. Kartsev, S. M. Novikov

The possibility of using physicochemical methods for treating nickel foam to increase its electrocatalytic activity in hydrogen and oxygen evolution reactions in an aqueous alkaline solution has been investigated. The modification of a 1 mm thick sheet of foam was carried out through its surface and included the physical deposition of a pulsed laser plasma for the formation of catalytic MoSx and MoSxSey films followed by their annealing. The effect of foam pretreatment by sulfurization in H2S under varying conditions, and the formation of catalytic layers with different structures and compositions was investigated. The greatest improvement of the electrocatalytic performance of the foam was exerted by thin-film coatings of molybdenum sulfide and sulfide/selenide with a nanocrystalline structure formed on the surface of a foam with a Ni3S2 underlayer. The possibility of the synergistic effect of the formed phases was analyzed by thermodynamic calculations in the frame of the density functional theory. For the optimal composition of the modified layers, the overvoltage of H2 evolution (for a current density of 10 mA/cm2) decreased to 155 mV, and the overvoltage of O2 evolution did not exceed 160 mV. The electrocatalytic characteristics obtained by this treatment are not inferior to those for the best modern electrocatalysts created on nickel foam by widely used methods of hydrothermal synthesis or electrodeposition.

Graphene is a promising material due to its unique chemical, physical, mechanical and thermal properties. The paper describes the synthesis method of a nanocomposite material based on graphene modified with nanoparticles of iron oxides, which is an effective sorbent of organic pollutants contained in aqueous media. Graphene production by chemical reduction of graphene oxide is the most flexible and popular method, which allows to obtain composite materials of various graphene-based structures. Chemical reduction of graphene oxide was performed using gamma-lactone 2,3-dehydro-L-gulonic acid (ascorbic acid). The method of obtaining the composite under investigation includes the treatment of the hydrogel obtained with supercritical isopropanol, which makes it possible to obtain a graphene aerogel containing nanoparticles of iron oxide (II, III). Analysis of the specific surface area and porosity showed an increase in the specific surface area of the aerogel by ~ 7 times as compared with a hydrogel dried under normal conditions in air. The diffractometric analysis of xerogel and aerogel samples suggests, that during supercritical drying in an organic fluid, the processes of reduction of iron hydroxide to iron oxide (II, III) proceed. The sorption capacity of hydro- and aerogel was studied using the example of extraction the molecules of the organic dye methylene blue from aqueous solutions in static mode (batch method). The results of the experiments showed that the maximum values sorption capacity for the methylene blue model dye were 1370 and 1326 mg/g for hydro- and aerogel, respectively.

Keywords: hydrogel, aerogel, supercritical processing, graphene oxide, iron oxides, ascorbic acid.
