The article presents the calculation of the chemical composition of the intermetallic composition based on the Ni₃Al compound using the doping balance formula, while the average electron concentration is the number of valence electrons per unit atomic mass of the composition; studies of structural and phase transformations in an intermetallic alloy based on Ni3Al depending on high-temperature treatment and during long-term tests at temperatures of 1150, 1200 and 1250 °С. The constructability of the structural alloy was experimentally established when testing the casting of blanks of the nozzle blades of the compressor turbine of a promising helicopter engine.

Technological plasticity, deformation mechanisms and dependence between mechanical properties and the conditions of deformation of titanium alloy VT30 were studied in present work. Samples in cast and forged states were examined. The samples were deformed on a pile driver and press at different temperatures, also forging and stamping were carried out. The results showed that the VT30 alloy has better properties in the forged state. In addition, optimal conditions for pressure treatment of titanium alloy VT30 were obtained.

In this work static and fatigue characteristics of welded joints of heat-resistant aluminum alloys V-1213 and 1151 were studied. Mechanical and service-life tests of flat welded structurally similar samples of fuselage elements made of heat-resistant aluminum alloys V-1213 and 1151 welded by laser-beam welding and friction stir welding were carried out. The assessment of the survivability of welded joints was evaluated with introduced stress concentrators. Comparative assessment of cyclic durability to failure was made on structurally similar welded samples.

New type of the energy carrier include magnesium-ion batteries, which represents potentially more effective and ecologically safe alternative to existing storage technologies. The main types of anode, cathode and electrolyte materials for magnesium-ion batteries, ensuring efficient transfer of Mg²⁺ cations and possible cyclic durability, are considered. In the article advantages and disadvantages of this technology, its potential for application in different areas also are analyzed.

Polymer binders with an energy-efficient curing mode are compositions containing hardeners and curing accelerators that are capable of curing the polymer system at low temperatures (120–150 °C), with minimal time, while maintaining the increased strength and thermomechanical characteristics of PCM, derived from it. This paper presents a technology for the development of a polymer binder with selection of a curing system to obtain an epoxy composition with an energy-efficient curing mode as part of import substitution issues.

The review presents the features of fatigue crack propagation in composite materials (CM) based on aluminum alloys reinforced with silicon carbide (SiC) particles with different volume content under cyclic loading conditions. The influence of the volume content and size of SiC particles on the growth rate of a fatigue crack in  CM under the action of cyclic loads is considered. The results of studying the influence of the CM structure on the growth rate and development of cracks during cyclic tests are presented.

A comprehensive assessment of the retention of strength properties of carbon fiber plastic of the VKU-59 brand under tension, compression, bending, interlayer shear at test temperatures of –60, +20, +80 and +105 °C was carried out in the initial state and after climatic influences in a tropical climate chamber for 1 and 3 months, heat and humidity aging for 1 and 3 months, thermal aging for 500 and 1000 hours. The influence of the mycological environment and process fluids on the tensile strength of carbon fiber reinforced plastic in bending and compression was studied. To confirm the viability, samples of VKU-59 carbon fiber plastic were tested in tension and compression after 3 months of storage.
