such as samarium, neodymium, and lanthanum

The effect of small additions of cerium-group rare-earth metals such as samarium (Sm), neodymium (Nd) and lanthanum (La) on the properties of a light high-strength structural magnesium IMV7-1 type alloy of the Mg – Y – Gd – Zr system, where yttrium (Y) and gadolinium (Gd) are yttrium-group rare earth metals, has been studied. It is established that the presence of small quantities of samarium in the IMV7-1 alloy contributes to an increase in its strength properties upon heat treatment (aging) and makes it possible to reduce the time to reach the maximum strengthening. In the case where two other cerium-group rare earth metals, neodymium and lanthanum, are present in the IMV7-1 type alloy, the strengthening upon heat treatment (aging) is also observed, but to a much lesser extent. It has also been established that, as the contents of the main alloying elements (yttrium and gadolinium) are simultaneously increased and samarium is added, the maximum strengthening of the alloys under study gradually increases, and the time to its achievement decreases. The fact that the alloying with samarium results in substantially higher strengthening of the IMV7-1 type alloy than that provided by neodymium and lanthanum is explained by a much higher solubility of samarium compared to these of neodymium and lanthanum in solid magnesium.
Keywords: magnesium alloys, rare earth metals, solid solution decomposition.

By firing polyurethane foam templates (“STR” brand, 12 pores per cm, China) with a porosity of ~ 65 % at 1200 °С, an open-pore calcium phosphate foam ceramics was obtained using a highly concentrated suspension based on synthetic hydroxyapatite, heat-treated at 800 °С, monocalcium phosphate monohydrate and 0.8 % polyvinyl alcohol. The resulting calcium phosphate foam ceramics after modification in the SBF (Simulated Body Fluid) solution concentrated 5 times (SBF´5) consisted of β-tricalcium phosphate, β-calcium pyrophosphate and biomimetic apatite, had a porosity of 53 – 59 % and a static strength of ~ 0.05 MPa. The formed biomimetic apatite, consisting of amorphous calcium phosphate Ca9(PO4)6 and apatite tricalcium phosphate Ca9HPO4(PO4)5OH, crystallizes into β-tricalcium phosphate at 1200 °С. Calcium phosphate foam ceramics modified with biomimetic apatite, after soaking in 5 % hydroxyapatite gel and SBF´5, which simulating a bone defect in vitro, in parallel with the formation of biomimetic apatite, is partially destroyed, which confirmed its high bioactivity and degradation.

transparent polymer on the basis
of 2-metoxycarbonylparacyclopropylestyrene
with glicidilmethacrylate
K. G. Guliyev, S. B. Mamedli
The new polyfunctional optically transparent polymer on the basis of 2-methoxycarbonyl paracyclopropyl styrene and glycidyl methacrylate has been synthesized. The compositions and structures have been established and the parameters of copolymerization of the synthesized copolymer have been found. The copolymerization constant values on Feineman – Ross equation (r1= 1.36, r2 = 0.30) and Q – e parameters on Alfrey – Price (Q1 = 2.573, е1 = –0.846) have been calculated. It has been detected that 2-methoxycarbonyl paracyclopropyl styrene is more active monomer than glycidyl methacrylate. The parameters of the copolymer microstructure have been determined. In comparison with polystyrene, the obtained copolymer has a higher refractive index. It has been established that the degree of light transmission (= 1.5820) is 88 – 90 %. Depending on the composition of the optically transparent copolymer, the change rate of the light transmission index has been studied. It has been shown that the synthesized copolymer exceeds polystyrene and glycidyl methacrylate on the main exploitation indices and shows the high optical transparency, which allows its use in the manufacture of details of optical devices.

Using the approach of oxidative constructing due to diffusion saturation, massive samples of compact metal-ceramic composite materials with a gradient structure were obtained: a nitride ceramic shell is a near-surface layer of ZrN, a solid solution of nitrogen in zirconium is a core, which is a solid solution of nitrogen in zirconium. The synthesized composites have better strength indicators compared to the original metal blanks. Under compression conditions, composite samples ZrN – Zr are characterized by plasticity, under bending conditions, they are brittle. The applied approach of oxidative design makes it possible, in comparison with traditional methods, to obtain rather efficiently and economically gradient ceramic-metal samples of products with dimensions and shapes that maximally repeat those of the original metal workpiece.
Keywords: composite materials, nitride ceramics, zirconium nitride, oxidative constructing, mechanical properties.

Obtaining hybrid nanostructures based
on graphene and nano-ZrO2
A. M. Afzal, E. A. Trusova, A. A. Konovalov
A technologically promising method for obtaining nanostructured graphene/ZrO2has been proposed. Its main idea is to use suspensions of graphene and nano-ZrO2and create conditions for the interaction of graphene sheets and ZrO2crystallites to form a hybrid nanostructured powder without the formation of new chemical bonds. The oxygen-free graphene sheets with thickness of several nanometers were obtained by sonochemical method in N,N-dimethyloctylamine-aqua emulsion. Nano-ZrO2 powder with average crystallite size of 8.1 nm was synthesized by sol-gel method. The morphology and phase composition of all synthesized objects (nano-ZrO2, graphene, composite) were studied by using a set of instrumental methods (transmission electron microscopy (TEM) and electron diffraction, x-ray diffraction (XRD), electron energy loss spectroscopy (EELS), nitrogen adsorption-desorption, diffusion aerosol spectrometry (DAS) and elemental analysis). It was shown that the proposed method allows obtain chemically homogeneous mesoporous hybrid powders consisting of graphene sheets and ZrO2 crystallites with a size of 8 – 13 nm fixed on them. We investigated an effect of duration of ultrasonic impact to graphite on the morphology of the hybrid and the mechanism of its formation. According to the results of a comprehensive analysis of the obtained data, the mechanisms for the formation of graphene suspension in emulsion and a nanostructured hybrid during the interaction of crystalline ZrO2 and oxygen-free graphene sheets in an aqueous-organic medium was proposed. The developed hybrid nanostructures are highly demanded innovative raw-products in the production of (photo)catalysts for a wide range of processes, sensor, ceramic and electrical materials, and materials for medical and biological purposes.
Keywords:nano-ZrO2, oxygen-free graphene, nanopowdery composites, graphene based hybrid nanostructures, sonochemistry.

Influence of rigid and flexible matrices
on ultimate strength and fracture mechanisms
of polymer composite materials upon impact
and static loading conditions
I. K. Krylov, N. V. Korneeva, V. V. Kudinov
An universal method “Break upon Impact and Static” (RUS) has been developed for the experimental determination of the ultimate strength properties of polymer composite materials based on multifilament nanocrystalline ultra-high molecular weight polyethylene (UHMWPE) fibers, which differs in the method of fixing the sample in a testing machine.The method is carried out using a uniform BIS-sample with an intermediate matrix at the ends and equipment for its attachment to the platforms of testing machines. The sample is a round composite rod composed of the fibers and matrices under investigation, which is held in the tooling by an additional matrix that fixtures it under various loading rates. The RUS method was used to study the properties and mechanisms of destruction upon impact and in a static situation of anisotropic polymer and hybrid composite materials (PCM and HCM) based on flexible and rigid matrices reinforced with hybrid fibers of carbon, aramid, and UHMWPE-fibers activated by non-equilibrium low-temperature plasma. The breaking loads under low-velocity impact and static bending conditions, relative deformation, specific absorbed-in-fracture energy, work of adhesion, shear strength, and other properties are determined. It was found out that the plasticity of the matrix and the hybrid fiber composition affect the properties and fracture mode of PCM and HCM. For the destruction of HCM with a flexible matrix upon impact, a load twice as large as for composites with a rigid matrix is required. HCMs have the highest strength, in which at all stages of loading up to failure, joint deformation of the matrix and the reinforcing fiber occurs. The mechanism of deformation and destruction of anisotropic HCM upon impact is stepwise, while the nature of the deformation curve is zigzag. In statics, the deformation proceeds smoothly. By changing the ratio of carbon and UHMWPE-fibers during hybridization, it is possible to control the properties of HCM and improve its specific properties. The combination of carbon and UHMWPE-fibers in a hybrid fiber for reinforcing a flexible matrix makes it possible to create a material with a delayed fracture. It has been established that for HCM based on a flexible matrix reinforced with a hybrid fiber combining 20 % carbon and 80 % UHMWPE fiber, the fracture load increases by factor 2, the specific fracture work by 42 %, relative deformation by 68 %.
