Intermetallic alloy based on a Ti₂AlNb compound are the most promising high-temperature materials for gas turbine engines operating up to a temperature of 700 degrees Celsius. In this paper, the technology of hot pressure treatment of a cast billet on a plate with a thickness of 25 mcm is studied. The technology included three comprehensive forging of the ingot billet, forging by drawing the intermediate billet and its subsequent rolling to the final size. The influence of heat treatment on the macro and microstructure of plates is studied. The chosen scheme of hot deformation and the mode of heat treatment provides an increased level of mechanical properties in the plates.

In this work, the samples of alloy 6013 of the Al–Mg–Si–Cu system after low-temperature thermomechanical treatment (LTMT) according to the scheme: quenching → aging → deformation → aging were studied by dark-field methods of transmission electron microscopy. The analysis of the structure of precipitates of hardening phases and dislocation structure in the volume of grains after different degrees of cold hardening of LHMT is carried out. It is shown that LHMT affects the formation of the structure of hardening precipitates, contributing to both heterogeneous nucleation at dislocations and homogeneous nucleation in the bulk of grains, due to the intensification of diffusion processes.

Provides an overview of methods for producing porous aluminum, its properties, advantages and disadvantages, and considers the use of aluminum foamed materials in the aerospace and mechanical engineering industries. It has been established that the mechanical properties of foam aluminum depend on the size and location of the pores, as well as on the method of its production; carrying out the process of modeling the deformation of samples with different pore diameters and the type of porous structure will make it possible to control the mechanical properties of a porous aluminum alloy.

A metal composite material (MCM) based on an aluminum corrosion-resistant alloy of the AMg6 brand, containing 22.5 % (vol.) Silicon carbide, obtained by mechanical alloying, has been investigated. Aspects of the formation of the MCM structure based on chips and powder from this alloy are considered. The influence of the initial components on the structure of the dispersion-strengthened MCM was investigated, and samples were made from this composite material.

The article notes the results of studying the surface of VKU-30K.UMT49 carbon fiber-reinforced plastic without and with its treatment with atmospheric pressure plasma (APP), which is one of the most advanced methods of surface preparation for various adhesion processes, based on the study of the phenomenon of wetting and the theory of adhesion. The results of the effect of APP on the strength of an adhesive bond based on VKU-30K.UMT49 carbon fiber-reinforced plastic, the roughness of the surface of the carbon fiber and its microstructure, the results of the free energy of the surface and its components and the work of adhesion according to the method of Owens–Wendt–Rabel–Kaelble were obtained.

Today wings for Boeing 787 and Airbus A350 aircraft are made of polymer composite materials in the form of prepregs based on carbon fiber, the blanks of which are molded in an autoclave. It is expected that by 2025–2030 will actively use the vacuum infusion method, which will require global research on the selection of binding and reinforcing materials, development of the vacuum impregnation and curing process, automation and development of new technological methods for laying out workpieces of parts, accelerating the process and shortening the cycle time.

Epoxy oligomers are one of the most widespread synthetic polymers who during already enough long time apply to manufacturing of paint and varnish materials. Possessing number of valuable properties, epoxy paint and varnish materials have also shortcomings for which elimination use different receptions, including physical and chemical updatings using different mono- and elastomeric, silicon- and organophosphorous and other connections. The main attention is given to use of different modifiers for improvement of operational properties of anticorrosion paint coatings.

In this work was explored the removal possibility of strippers by acid, alkaline and organic bases, was explored the corrosion effect of strippers for typical metal materials for aircrafts the aluminium alloys 1163-T, B95-T2, the steel 30HGSA. The fact of the corrosive effect of strippers for metal materials was experimentally substantiated. The negative impact of the several strippers (in the case of their mixing) for the surface of the fragments of the aluminum alloy cladding, and, accordingly, on the resource characteristics (low-cycle fatigue), is studied, using the example of the B95-T2 alloy.

Nondestructive testing results of carbon fiber reinforced plastics (CFRP) specimens at the development and testing process are given at that paper. Ultrasonic pulse-echo technique is the most applicable for CFRP monolithic panels and curved beam specimens testing. It is shown that ultrasonic testing allows optimizing the mode in the process of developing molding modes for new CFRP grades. At the test stages it allows to exclude defective specimens from the testing process and estimate the sorts and damage sizes after the tests.

The document includes the below main trends in development of acoustic non-destructive testing methods in aviation industry: automation and enhancement of the sensitivity the testing, development of Procedures for acoustic non-destructive testing methods for products in case of repair and use of products, probabilistic assessment of the outcomes of the ultrasonic non-destructive testing, mathematic simulation of the ultrasonic non-destructive testing, development of the ultrasonic non-destructive testing by applying state-of-the-art technologies, development of the low-frequency acoustic testing methods, development of a Procedure on training of specialists who conduct NDT. The experience of NRC «Kurchatov institute» – VIAM is pointed out to show an example on the implementation of main trends on ultrasonic testing development.

In order to protect polymer materials in particular polyurethanes and similar materials from biodeterioration by microscopic fungi, seven fungicidal compounds of the guanidine series were synthesized and their effectiveness was investigated in various concentrations. Among the tested compounds, the most effective is the first fraction of polyhexamethylene guanidine n-octylphosphonate (code B1), which completely suppresses the growth of all studied micromycetes at a minimum concentration of 0.01 % by weight. At a lower concentration of 0.001 % by weight, compound the first fraction of polyhexamethylene guanidine n-octylphosphonate inhibits the growth of most of the studied micromycetes, with the exception of the Aspergillus niger culture.
