The work is devoted to studying the melting ranges of the base Zr – Si eutectic composition depending on the content of the heterophasic powder component in the ZrB2 – ZrSi2 – MoSi2 and HfB2 – HfSi2 – MoSi2 systems in an amount of 30 – 90 % obtained by the method of self-propagating high-temperature synthesis (SHS). The melting range of the mixture Zr – Si was 1420 – 1440 °C, while the addition of SHS-powders ZrB2 – ZrSi2 – MoSi2 led to an increase in the melting onset temperature Тmelt.onset to 1460 – 1560 °С and the complete melting temperature Tmelt.complete to 1480 – 1670 °C. The addition of HfB2 – HfSi2 – MoSi2 powders had a weak effect on the values of Тmelt.onset (1390 – 1430 °С), but led to an increase in the values of Tmelt.complete to 1510 – 1550 °С. X-ray phase analysis showed that the remelted samples contained ZrB2/HfB2, ZrSi2/HfSi2, MoSi2 phases and Si, with the number of phases being directly proportional to the content of SHS powders in the composition of the Zr – Si mixture. The ingots were characterized by a homogeneous structure consisting of a silicon matrix, ZrSi2/HfSi2, MoSi2 disilicide grains, with ZrB2/HfB2 diboride inclusions.
Keywords: hafnium diboride, zirconium diboride, self-propagating high-temperature synthesis, high-temperature ceramics, heterophase ceramics, composites.

Phenomenon of reversion after ageing in magnesium alloys with gadolinium and samarium
L. L. Rokhlin, T. V. Dobatkina, N. Yu. Tabachkova, I. E. Tarytina, E. A. Lukyanova
The parameters of reversion after hardening ageing of magnesium alloys containing two rare-earth metals: gadolinium (yttrium group) and samarium (cerium group) were determined at various ratios of their contents. The reversion was observed at short annealing at 250 and 300 °С beginning with 5 minutes after preliminary ageing at 200 °С up to maximum hardening and consisted of significant softening of the alloys then. Measurements of the electrical resistance indicated, that during softening the reverse dissolution of the rare-earth metals in magnesium-base solid solution takes place with diminution of the hardening particles quantity, precipitated during ageing before The reverse dissolution of the rare-earth metals into solid magnesium increases with elevating annealing temperature after ageing from 250 to 300 °С and with increase of the gadolinium to samarium ratio in the alloys.
Keywords: magnesium alloys, rare-earth metals, reversion after ageing, solid solution decomposition.

Dicarboxylate-substituted octacalcium phosphates for hydrogel filling and resorbable ceramics fabrication
A. A. Tikhonov, E. S. Klimashina, P. V. Evdokimov, E. V. Kukueva, A. S. Biryukov, V. I. Putlayev, I. M. Scherbackov, V. E. Dubrov
The main features of the synthesis of carboxylate-substituted analogs of octacalcium phosphate Ca8(HPO4)2(PO4) 4·5H2O (OCP) by hydrolysis of brushite (CaHPO4·2H2O) and tricalcium phosphate α-Са3(РО4)2 (α-TCP) in buffer solutions based on the salts of succinic, adipic, and citric acids were summarized. The synthesis of succinate-substituted (Suc@OCP) and adipinate-substituted (Adi@OCP) OCPs gives the powders with Ca8(HPO4)2 – xАx(PO4)4·zH2O (А= Suc, Аdi) composition. Thermolysis of substituted OCPs results in a mixture of β-Са3(РО4)2 (β-TCP) and hydroxyapatite Са10(РО4) 6(ОН)2 (HAp). Thermolysis features include the absence of an apatite-like decomposition product of pure OCP and higher decomposition temperatures compared to the pure OCP. Suc@OCP and Adi@OCP powders were used for the filling of hydrogels based on polyethylene glycol diacrylate (PEGDA) for the creation of a deformable composite implant by a stereolithographic 3D printing method, and fabrication of biphasic TCP/ HAp ceramics.
Keywords: octacalcium phosphate, carboxylate-substituted octacalcium phosphates, brushite, tricalcium phosphate, succinic acid, adipic acid, citric acid, thermolysis, composite, hydrogel, 3D-printing, stereolithography, ceramics.

A review of studies of the mechanical properties of human and animal heart tissues has been performed. Based on literature data, a form of approximating function is found for the dependence of the Young’s modulus of the ventricles of the human heart on the magnitude of the deformation. The average values of the Young’s modulus and other elastic constants were calculated and compared with the known experimental values. The coefficients C1 and C2 of the two-parameter hyperelastic myocardial MooneyRivlin model are calculated.
Keywords: mechanical properties, Young’s modulus, Mooney – Rivlin hyperelastic model, hearth, myocardium.

Low-temperature deformation of Al – Ni – Fe – La system amorphous alloys
N. D. Bakhteeva, E. V. Todorova, D. V. Prosvirnin, N. V. Petrakova, T. R. Chueva, E. O. Nasakina
X-ray amorphous ribbons of aluminum-based alloys doped with transition (Ni, Fe) and rare-earth (La) metals in various ratios were obtained by melt-spinning. The mechanical characteristics and fracture surfaces of the ribbons under conditions of uniaxial tension with speeds from 0,01 to 10 mm/min were studied. It was shown that with an increase in the rate in all investigated alloys, the strength limit increases and low plasticity remains. Inhomogeneous deformation is realized by the initiation and spread of shear bands. Mixed fracture surface indicates a brittle-viscous fracture with a high ratio of the viscous component. It was confirmed the significant influence of the scale factor on the strength characteristics of the ribbons. The tensile strength of the ribbons increases with iron content rising and nickel content decreasing when the influence of the scale factor is excluded. It is experimentally shown on ribbons with a low-melting tin coating that local heating in shear bands reaches the melting point of tin 231,9 °C.
Keywords: amorphous Al-alloys, mechanical properties, fractography, low-melting coating, alloying elements.

Obtaining mesoporous materials based on titanium dioxide modified by magnetite with high adsorption capacity and photocatalytic activity
T. V. Kusova, I. A. Yamanovskaya, N. S. Kopeikina, A. S. Kraev, A. V. Agafonov
Crystalline composite structures based on titanium dioxide modified by magnetite particles with improved sorption and photocatalytic properties were obtained by a microwave-assisted method. This method is based on a polyol method synthesis of titanium glycolate using microwave heating and followed by the water treatment under microwave heating at 2.45 GHz, without using the calcination stage at high temperatures. It was found that the treatment of titanium glycolates in water under the influence of microwave heating leads to the formation of the crystal structure of titanium dioxide (polymorphic anatase modification). Using scanning electron microscopy, it was shown that during the synthesis of composite structures based on titanium dioxide, the formation of particles of a spherical and rod-shaped form. The resulting materials were characterized by electron microscopy, X-ray phase analysis, dynamic light scattering, and low-temperature nitrogen adsorption/desorption. The analysis of the influence of structural and morphological features on the adsorption capacity and photocatalytic activity of the composites is carried out. A comparative analysis of the photocatalytic activity of the obtained composites in the decomposition of the Rhodamine B dye under UV radiation showed that the most effective dye removal (~ 99 %) were observed in the presence of both spherical and rod-shaped composite structures as catalysts containing 1 % of magnetite.
Keywords: titanium dioxide, microwave synthesis, mesoporous, magnetite, photocatalytic activity.

The results of measuring vibration parameters depending on the applied axial load, the relative displacement velocity, and the material of the mandrel holding the carbide element are presented. An assessment of the effort created by vibration in the friction zone, and its effect on the destruction characteristics of the abrasive were carried out. The influence of vibration parameters on the energy distribution between the thermal and mechanical components during friction is shown.
