The article discusses the possibilities of preparing high-quality powder materials from heat-resistant light alloys based on refractory monoaluminides of nickel β-NiAl and ruthenium β-RuAl for the manufacture of compact samples/products of complex shape using additive technologies with minimal final machining. Additive technologies are based on the use of spherical precursor micro-powders with a regulated granulometric composition, good fluidity and an oxide-free surface. The possibilities of obtaining precursors from RuAl-based alloys by plasma spheroidization of powders obtained by crushing mixtures from scrap samples of alloys based on RuAl with various additives are considered.
Keywords:nickel and ruthenium monoaluminide, spherical powders, precursors, spraying, granulation, plasma spheroidization.

The biocompatibility of polylactic-co-glycolic acid (PLGA) scaffolds for tissue engineering constructions can be significantly improved by autologous mesenchymal stem cells (MSCs) colonization. However, the features of the cell colonization procedure can generally affect the changes in the physical and mechanical properties of these scaffolds, which are mostly determined by their architectonics. To study this issue, in this work, we have formed and investigated three types of experimental PLGA samples: 1). molded monolithic blocks; 2). porous scaffolds formed by plasticization in supercritical CO2followed by foaming; and 3). electrospun fibrous non-woven scaffolds. The quantitative XTT test showed the nontoxicity of all studied samples, as well as the greater efficiency of the dynamic cell colonization method compared to the static one. After 48 hours of samples incubation with cell cultures, their physical and mechanical properties were noted to change both at macro- and microlevels. These changes, in our opinion, occur due to the processes of hydrolytic and enzymatic PLGA hydrolysis, as well as the effect of adhered MSCs on the scaffold internal structure and surface morphology. Similar transformations of certain physical, mechanical and structural properties of scaffolds based on other biodegradable polymers or their compositions can also occur as a result of their colonization with various cell cultures, which should be taken into account when applying the scaffolds to develop tissue engineering constructions.
Keywords:polylactic-co-glycolic acid, bioresorbable scaffolds, mesenchymal stem cells, tissue engineering, injection molding, electrospinning, superficial fluid technologies, hydrolytic and enzymatic degradation.

Features of spark erosion fine
Mo and Nb alloys powders
N. V. Shchipalkina, S. V. Pshenov, V. A. Chursin,
D. S. Sadilo, E. G. Kolesnikov
Сharacteristics of spherical powders of (Mo,Nb) and (Nb,Mo) alloys prepared by spark erosion technique are described. Two regimes (U = 24 V, I = 10 A and U= 24 V, I = 20 A in distilled water) were chosen for powder preparation. The pyrolysis of dielectric liquid during spark erosion leads to the formation of stable oxides NbO and NbO2 as thin crusts and spherical inclusions from 10 nm to 10 µm in powder particles. The largest deviations from electrode compositions (from 3 to 7 wt.% Nb) are inherent to Mo alloys with 9 and 10 wt.% of Nb. The number of NbO and to a lesser extent NbO2 inclusions in spherical powder increase with increasing of Nb content in alloy, but only in series of (Mo,Nb) samples. Such regularity is not observed for (Nb,Mo) series. Decrease of current value results the change of granulometric compositions of spherical powders. The main fraction of powders at I = 20 A is 40-80 µm and I = 10 A is 20-50 µm.
Keywords:spherical powders; refractory metals; Mo and Nb alloys; spark erosion; additive technologies.

The main advantages of direct laser deposition (DLD) of large-sized products are discussed on the example of the internal core baffle of a pressurized water reactor (VVER core baffle). The problem of product damage during operation as a part of reactor was considered. Powder materials of stainless steel with Russian grades 08Cr18Ni10Ti and 10Cr16Ni25MoTi were produced to develop the DLD process. Optimization of the core baffle design was carried out to improve operating reliability. Samples and fragments of the core baffle were manufactured by DLD method with complex research and tests. The concept of an experimental DLD unit for large-scale parts were developed.
Key words: internal core baffle of pressurized water reactor, direct laser deposition, powder material, 08Cr18Ni10Ti steel, 10Cr16Ni25MoTi steel.

A technology for obtaining complex nitrogen- and carbon-containing precursor materials V(51 – 43) – Al(30 – 36) – N(13,4 – 16,4) – C(2,7 – 6,0) was developed and tested on an experimental scale by nitriding by the method of self-propagating high-temperature synthesis of mixtures of V(65 – 50) – Al master alloys powders with graphite. The ratio of nitrogen to carbon in precursors can be varied over a wide range — N/C = 5.5 – 2.2. Using X-ray phase analysis, it was found that nitrogen in these materials is in the form of AlN and VN nitrides, and carbon is in the form of V2C, VC and V2Al0.96C1.1carbides. The possibility of replacing graphite in the charge of out-of-furnace aluminothermal smelting of the V – Al – N – C master alloy with an alternative precursor V(51) – Al(30) – N(15) – C(2.7) has been experimentally confirmed. Using the methods of X-ray phase analysis, electron microscopy, and X-ray spectral microanalysis, it was found that the smelted using this precursor V – Al – N – C master alloy ingot is identical in phase composition and in distribution uniformity of nitride and carbide inclusions to alloy ingots that were smelted using other carbon-containing materials. The content of nitrogen, carbon and oxygen in the ingot meet the requirements of the technical specifications for V – Al – N – C master alloy.
Keywords:alloy V – Al – N – C, precursor, self-propagating high-temperature synthesis, aluminothermy, nitriding, nitrides, carbides, phase composition, structure.

Magnetic properties of SMC materials based
on iron powder
with multilayer insulating coating
G. A. Govor, A. O. Larin, O. F. Demidenko, A. L. Zheludkevich
Magnetic properties of composite magnetically soft (SMC) materials based on iron powder ABC100.30 depending on the thickness of the insulating coating based on phosphorus oxide are investigated. It was found that for SMC materials with a three-layer coating of particles, the magnitude of magnetic hysteresis is minimal. As a result, the remagnetization losses for a materials with three-layer insulating particles coating are reduced by an order of magnitude in comparison with composites based on powders with a single-layer coating. The developed materials with magnetic permeability µ = 100 – 150 and induction up to 1.8 T are promising for use in the frequency range up to 1 MHz in the manufacture of various types of electrical devices.
Keywords: SMC material, insulating coating, saturation magnetization, magnetic permeability, electromagnetic losses.

In the work presents the results of a study of the influence of the effect of a continuous ion beam of the composition (Ar++Zr+) with an ion energy E ≈ 20 keV and an irradiation dose D ≈ 5·1017ion/cm2 on the phase composition, chemical state, microhardness, wear resistance during friction against an abrasive and corrosion resistance of tungsten-free hard alloys of the TiC – TiNi system. Analysis of the structure, morphology, and chemical state of the samples before and after ion treatment was carried out using scanning electron and scanning probe microscopy, as well as X-ray photoelectron spectroscopy and X-ray diffraction analysis. The features of the change in the physicochemical state of the tungsten-free hard alloy of the “TiC – TiNi” system subjected to continuous ion beam irradiation are revealed. It has been experimentally established that ion-beam treatment provides an increase in microhardness, wear resistance and corrosion resistance of the hard alloy.
Keywords: continuous ion beam, tungsten-free hard alloys, surface modification, titanium carbide, titanium nickelide, microhardness, wear resistance.

The article considers the influence of such parameters as infill density, infill line directions and line width on the mechanical properties of samples made of polyethylene terephthalate glycol by FDM-printing. Mathematical expressions were obtained on the basis of the conducted research. These mathematical expressions allow to calculate the expected mechanical properties of the studied PET-G brand under uniaxial tensile, static and impact bending. The influence of variable FDM-printing parameters on the formed level of product properties is investigated, which will allow the selection of their values depending on the required tasks.
Keywords: mechanical properties, FDM-printing, polyethylene terephthalate glycol, infill density, infill line directions, line width.
