The article presents the results of research aimed at studying the structural and phase stability of a high-temperature intermetallic alloy based on nickel VIN4M. It is shown that the greatest effect of dissolution of the eutectic γ'-phase, affecting the stress state of the alloy of a certain chemical composition, is observed in the temperature range 1310–1330 °C. The critical points of material are determined after vacuum induction melting and vacuum induction casting by the method of directional solidification with a crystallographic orientation of <001> and the characteristics of alloy samples for short and long-term strength after hardening heat treatment.

According to the results of scientific and technical literature analysis one can conclude that a large number of factors influence the processes which take place during cooling, as well as the structure and properties after isothermal exposures. Among those factors there are structural and phase transformations features and the completeness of recrystallization processes. The effect of various cooling rates on the structure and properties of isothermally exposed metastable β-titanium VT47 alloy has been studied. It has been revealed that cooling in the selected rate ranges does not exert a significant effect on the Rockwell hardness and microstructure of the VT47 alloy. It has been shown that grains with an increased number of the secondary α-phase precipitates are characteristic for the initial stages of isothermal exposures.

Features of application of low-molecular weight siloxane rubbers are considered when manufacturing pressurizing materials. The comparative analysis sealants type of VICSINT, compounds and type of VGF.

The use of composite materials is carried out more on the widest scale. More and more relatively small, but structurally complex and critical parts of machines and mechanisms began to be made of polymers, and at the same time, polymers began to be used more and more often in the manufacture of large-sized body parts that carry significant loads. Polymer composite materials have firmly won a place among structural materials. Composite materials can no doubt be attributed to the most promising products of both modern and future industrial production.

Provides an overview of the highly porous ceramic materials currently used for filtration of metal melts and hot gases, filter manufacturers and methods for their production. Gas permeability and high specific surface area in combination with refractory properties allow using of highly porous oxides in processes carried out at high temperatures in chemical media when other materials are not applicable. Ways of improving the operational properties of porous ceramic filters, such as operating temperature, strength, oxidative resistance, bimodal porosity, as well as possibilities of improving the technological process of their production: reduced cost, increased environmental safety of production, reduced time of the technological cycle wereconsidered.

The difference in weathering of carbon-reinforced plastics on the exposed (front) and shaded (back) side of the samples was studied during the natural exposure in a moderately warm climate for 75 months. Surface profile parameters of the exposed samples were studied on both sides of the samples. Peak and valley height distribution peaks are 30–85% higher on the exposed side compared to the shaded side. The application of static load to the exposed or shaded side of the samples during the exposure resulted in different flexural strength.

The cold spray allows to develop coatings on different materials, and to give them wide set of functional properties. Besides this method of drawing coverings allows to recover the geometrical sizes of the details damaged in use and to carry out recovery of protective corrosion preventive coatings without labor-consuming dismantle of design. Simplicity and technological effectiveness of process, mobility of installations for drawing coatings by cold spray, allows to apply this method as in industrial conditions using the robotized systems, and in «field» conditions.

The article is devoted to issues in the field of creation of radar absorbing materials (RAM) in order to solve the problem of electromagnetic compatibility (EMC) in modern aircrafts. The characteristics of a number of RAM developed at FSUE «VIAM» are provided that are designed to ensure coordination and operability of aircraft antenna systems and to provide EMC for on-board radio-electronic equipment in the microwave range. The materials presented in the work differ in their overall dimensions, operating frequency range, method of attachment (application/installation) and have different purposes for use on aircrafts.

The content of 19 elements (B, Al, Si, P, Ti, Cr, Fe, Co, Ni, Zr, Nb, Mo, Hf, Ta, W, Se, As, Pb, Bi) in the samples of nickel alloys was determined by high resolution glow discharge mass spectrometry. The selection of analysis conditions is given. Spectral interference is eliminated by the use of high resolution. The correctness of the results obtained is confirmed by analysis of a certified standard samples of nickel alloy. The range of determined concentrations: 0,000002–53,4% (of the mass), the relative standard deviation does not exceed 0,05.

The application of the finite element method, smoothed particle hydrodynamics, and the discrete element method is considered. The paper deals with modeling of sea and freshwater ice, impact, explosive loading, three-point and four-point bending, compression, contact interaction «ship–ice» and «support–ice», falling from a height, and the use of reinforcement etc.

Operational characteristics of currently created materials and products of aviation equipment. Such conditions, especially in the winter period, largely correspond to the quality of clothes and shoes. The paper presents the results of experimental studies of the thermal conductivity of different types of insoles for shoes. Physical and mathematical models of heat transfer are proposed when a person moves from a warm room to the street. The thermal insulation ability of three types of insoles for shoes was studied and time is shown.
