and LDPE + Bi2Te3
E. M. Gojaev, A. N. Mirzeyevа, A. Y. Ismayilova
The paper presents results of a study of the spectra of thermally stimulated depolarization PVDF + TlInS2, LDPE + Bi2Te3 and irradiated dose 50 kGr g rays composites PVDF + TlInS2 in temperature range of 300 – 450 K. It was revealed that not irradiated and irradiated composites PVDF + x vol.% TlİnS2 observed two distinct peaks, the intensity of the low-temperature peaks smaller than high-temperature peaks. With increasing volume content of filler the intensity as a low temperature and high temperature peaks are reduced. For composites LDPE + x vol. % Bi2Te3 detected single maximum, the intensity of which increases with the volume fraction of filler Bi2Te3 decreases. It was revealed that the composites PVDF +7 vol. % TlİnS2 and LDPE + 5 vol. % Bi2Te3 have distinct high peaks, relatively low values of the half-width of the maxima. This is probably due to the fact that in these composites integral surface of the interphase boundary attains its maximum (optimal) values of these composites should be relatively high electret properties.
Keywords: composites PVDF+TlInS2 and LDPE+Bi2Te3, g-radiation, depolarization, thermally stimulated current.

Structure and mechanical properties of sintered
(Al – 0.5 Si) – 40 Sn composite
N. M. Rusin, A. L. Skorentsev, M. G. Krinitsyn
The structure and mechanical properties of sintered samples prepared from a mixture of sprayed tin and Al – 0,5 Si powders were investigated. Sintering of the briquettes was performed at temperatures of 570 – 640 ° C during no more than three hours. It was found that the greatest influence on features of the formed structure and density of the sintered samples has the wetting angle of solid phase by liquid because its value defines the area of interphase surface and intensity of dissolution-precipitation processes of the solid phase´s atoms. Aluminum matrix has the highest connectedness and the samples have the lowest porosity after sintering at 600 °C when the dihedral wetting angle is small, but not zero, that is, in conditions of partial wetting of aluminum by liquid tin. The mechanical properties of sintered (Al – 0,5 Si) – 40 Sn composites were determined by compression tests. It was found that at fixed composition of the samples, their strength and ductility are mainly dependent on the degree of connectedness of the matrix, which is determined by peculiarities of the interaction between the liquid and solid phases during sintering. The samples with high connectedness of aluminum matrix and minimal porosity were the most ductile and have greatest strength.
Keywords: liquid phase sintering, Al – Sn alloys, structure and mechanical properties MMC.

M. S. Fedoseev, V. B. Shatrov, G. I. Shaidurova,
L. F. Derzhavinskaya
Hardening kinetics of epoxy-novolac resin (UP-643) hardened by isomethyltetrahydrophthalic anhydride under the action of various catalysts was investigated with use of the DSC method. Kinetic parameters and thermal effects of reactions were determined. Among the catalysts tested, tetrabuthylammonium chloride, magnesium(III)/iron(III) acetylacetonates, zinc chloride complex with imidazole proved to exhibit latent properties. Rheological properties of the epoxy binders containing the above latent catalysts were studied. The protracted pot life (up to 60 days) of these binders was ascertained as dependent on variable dynamic viscosity at room temperature. Under the action of the mentioned catalysts, heat-resistant net-shaped polymers were synthesized. These polymers were used to manufacture organoplastic composites that, in turn, were tested to determine their physic-chemical properties (under strain) and thermomechanical properties (under three-point bend). For the polymer obtained with use of latent tetrabuthylammonium chloride, the elasticity modulus and mechanical loss tangent as dependent on temperature and frequency of the load applied during the bending test were determined.
Key words: epoxy oligomers, anhydride hardening, catalysts, latency, polymeric materials, heat-resistance, physic-chemical properties.

Made internal revenue hydrogen of the two compounds with a layered structure of the superconductor FeSe0,88 and semiconductor MoS2 . When intercalation was used as molecular hydrogen (H2) and ionized hydrogen (H+) generated in a special ion source. In the case of FeSe0,88 intercalation hydrogen ions leads to a slight increase in the superconducting transition temperature of the compound. It is noteworthy that Tcm this connection may be slightly increased due to the magnetization being in contact with him in the ferromagnetic phase FeSe (in the to field 0,1 Т). In the process of intercalation of MoS2 with hydrogen, its weight is increased, the lattice parameter “C” that is associated with the increase in the distance between the layers increases from 12.241(6) Å to 12.297(5) Å. This, along with existing Van der Waals forces arise H - bond, which leads to the formation of hydride MoS2H0,38 and a spike of electrical resistivity (on the order against its value before the intercalation of hydrogen).

Modification of thermal reduced graphene oxide
by SF6/Ar plasma treatment
E. P. Neustroev, M. V. Nogovitcyna, V. I. Popov, V. B. Timofeev
Effect of SF6/Ar plasma on the properties of partially thermal reduced graphene oxide (GO) were studied by Raman spectroscopy, scanning electron microscopy, energy dispersive spectrometry and the currentvoltage characteristics. Samples were treated by SF6/Ar plasma up to 45 min at power from 100 to 250 W. The fluorine content and the resistance of the samples were determined. The fluorine content in GO is more than 20 % at treatment time 45 min. It is shown that the sharpest change in resistance occurs during the initial treatment in the plasma. In the subsequent processing there is a gradual increase in resistance, the value of which varies slightly during the heat treatment to the 450 °C. Not detected a noticeable increase in defects on the surface of graphene oxide after plasma treatment by the methods of Raman spectroscopy and electron microscopy. Fluorination in SF6/Ar plasma is explained by the formation of C – F bonds with the structure of graphene oxide.
Keywords: reduced graphene oxide, functionalization, plasmachemical treatment, sulfur hexafluoride, fluorination, electrical properties.

Mechanothermal synthesis of cobalt, iron
and titanium aluminides
V. A. Artukh, G. D. Nipan, V. S. Yusupov
The aluminides with compositions Al13Co4, Al13Fe4, Al13Co2Fe2 and Al3Ti were synthesized in air after mechanical activation of metals-precursors and followed thermosynthesis. The phase states of the synthesized aluminides as well as composites Al13Co4/SiO2, Al13Fe4/SiO2 and Al3Ti/SiO2 were analyzed before and after partial oxidation of metane POM. According to the X-ray powder diffraction data, the Al13Co4 crystallizes as Y-phase. During POM, along with the Y-phase, aluminum-low Z-phase formes. The sample Al13Fe4 is the eutectic mixture of monoclinic M-phase Al13 – xFe4 and aluminum, but the solid solution Al13Co2Fe2 crystallizes as homogeneous M-phase. The formation of Al3Ti in the air is accompanied by oxidation. With SiO2 as a substrate, intermetallics Al13Co4 and Al13Fe4, albeit corrosion-resistant to atmospheric oxygen up to 600 °C, decompose and form corundum Al2O3; mullite Al6Si2O13; and silicides CoSi2, CoSi, Co2Si, FeSi2, and Fe3Si. The phase transformations occurring during the coannealing of Al13Co4 and Al13Fe4 with SiO2 are described by the irreversible reactions. The Al3Ti aluminide doesn’t form silicides during the contact with SiO2 and the phase state of the composite 3 Al – Ti – 1,5 SiO2 doesn’t change at POM.
Keywords: mechanical alloying, imtermetallides, aluminides, thermosynthesis.

Composite model dependence of the mechanical
properties of anodic aluminum oxide on porosity
V. N. Simonov, L. P. Loshmanov, E. A. Markova
The results of the application of the theory of elasticity of composite materials to calculate the elastic moduli of anodic aluminum oxide (AAO). The basis of the proposed model AAO elasticity is the assumption that the space anodic aluminum oxide can be represented as a composite material in a matrix — bulk amorphous oxide filling the space between the pores reinforced hollow fiber wall thickness zero. The maximum error of this simplification in the range of porosity values actually used is for the Young’s modulus at 5 %, and for the shear modulus at 0.7 %. The results are in good agreement with the experimental data of other authors. Good agreement of the results gives hope that this approach can be applied in cases where the pores are filled AAO some material (adsorbent liquid, etc.) as possible, for example, in cases of using AAO as a material for cantilever sensors.
