Features of the supports structures’ processing for parts made of a metal-powder composition based on the Co–Cr–Ni–W–Ta system, manufactured by selective laser melting method, have been studied. As the main type of supports used for printing various types of parts, the block type was selected for the research. The analysis of advanced technological parameters of printing support structures, including delays of the laser beam movement when changing the trajectory, the beginning and end of the tracks, the transition between the tracks were held. Influence of the parameters on the quality of manufacturing supports was determined and optimal parameters for printing supports were selected.

The work is devoted to the study of the processes of hot and cold plastic deformation of hard-to-deform shape memory alloys of the Ni–Ti–Nb and Ni–Ti–Nb–Zr systems. The optimal modes of deformation treatment of these alloys, which ensure the production of semi-finished products without surface defects, have been determined. Investigations of the mechanical properties of hot-deformed and cold-deformed semi-finished products from alloys of the Ni–Ti–Nb and Ni–Ti–Nb–Zr systems have been carried out. It is shown that the selected treatment modes of these alloys provide a high level of mechanical properties of materials.

Manufactured material for CRM pipes with a diameter of 40 mm and a height of 30 mm. Tests of the material for CRM have been carried out in order to validate it. The metrological characteristics of the CRM were established, a metrological examination was carried out, and the conclusion on the verification of the CRM test results for the composition of the ML19 magnesium alloy.

The possibility of replacing acetic anhydride with phthalic anhydride when determining the hydroxyl groups contents in polyester 24K is discussed. Titrimetric analysis method obtained data on the content of these functional groups, consistent with previously analyzes. The reaction completeness was controlled by infrared spectroscopy, the results of which report on the successful process flow. Additionally, the reactivity of the product with an expired shelf life was checked.

Discusses the process of obtaining spherical granules of a metal composite material based on molybdenum with an initial fraction of 40‒63 microns. The results obtained during the research showed the fundamental possibility of spheroidization of granules of high-temperature metal composite materials based on refractory metals reinforced with particles of ceramic compounds. However, the need for a more thorough study and selection of spheroidization modes to minimize the formation of satellites on granules during processing in an electric arc discharge plasma is revealed.

Today, the wings of Boeing 787, Airbus A350 aircraft are made by automated laying out of prepregs with subsequent autoclave molding. Boeing and Airbus plan to replace the 737 and A320 aircraft in the coming years, and new materials and technologies need to be developed to ensure the production of these aircraft in the amount of 100 pieces per month. To introduce new processes and materials, research is being carried out on the selection of a binder, reinforcing fillers, development of the vacuum impregnation process, curing and automation in order to increase reliability, speed up the process and reduce cycle time.

The article presents a scientific and technical literature review of copper-based hybrid composite materials (CM). Common combinations of reinforcing components for the manufacture of hybrid composite materials are presented. The main methods for fabricating copper-based hybrid CMs are briefly mentioned. The influence of a combination of various types of reinforcing components and their volume or mass content on the mechanical, thermophysical and tribological properties of hybrid CMs based on copper is considered. A comparison of the characteristics of hybrid CMs with matrix alloys or metallic CMs of similar systems is given.

In present work electrical insulating coatings based on BaO–B₂O₃–SiO₂ glass-forming system for use in electronic circuits on a metal substrate were investigated. The synthesized compositions in terms of chemical resistance belong to the class of stabilized glasses. The tests were showed that the experimental compositions significantly exceed the known coatings in terms of dielectric properties. Positive data on the stability of dielectric properties and on the quality of the defect-free coating layer were obtained.

Low-cycle fatigue has been investigated under a «hard» loading cycle and under a «soft» loading cycle of a heat-resistant deformable VZh175 alloy at room and two operating temperatures at three asymmetry coefficients. The tests were carried out at a sinusoidal loading cycle with a frequency of 1 Hz. Comparison of stresses at «soft» and «hard» loading cycles is carried out. A comparison of the fatigue curve and a priori curves obtained using the characteristics of short-term strength is carried out.

The results of the calculations and the obtained experimental data show the need to take into account the distribution of strain fields on samples with stress concentrators for the selection of the correct gage of optical strain gauges. The ability to install certain gage of optical sensors with specific geometric parameters of the sample allows one to obtain the values of the stiffness and deformation characteristics on the sample with holes close to the values of the material characteristics, which can be used, for example, when carrying out research work in conditions of limited materials.

Extremophilic microorganisms are able to survive under extreme environmental conditions. The article is devoted to a review of research works on the study of extremophilic micromycetes, as well as the search among them for species known as destructors of polymeric materials. Such groups of extremophilic micromycetes as thermophiles, xerophiles, and oligotrophs, capable of surviving at high ambient temperatures, low humidity and lack of nutrients, are considered.In each group of extremophilic microorganisms, species of micromycetes were found, which were repeatedly noted as destructors of polymer materials.
