TRENDS IN THE DEVELOPMENT OF HIGH-TEMPERATURE METAL MATERIALS AND TECHNOLOGIES IN THE PRODUCTION OF MODERN AIRCRAFT GAS TURBINE ENGINES

In the present work, the trends in the development of modern high-strength metallic materials and technology for producing loaded parts of aircraft gas turbine engines (GTE) are analized. A steady increase of the efficiency operating parameters of the gas turbine engine requires constant increase in operating temperature and gas pressure in each section of the engine starting with the fan, then the compressor, then the combustion chamber and the turbine. The highest combinations of stresses and temperatures are experienced by the rotating disks and blades of GTE high-pressure turbine. Therefore, now they are made with unique technologies from expensive materials. In the future, it is possible to use eutectic natural composite alloys based on nickel and niobium in the production of GTE blades. Metal materials with their unique set of properties will remain the basis of aviation gas turbine engines.

Keywords: aviation gas turbine engine, gas temperature, heat resistance, directional crystallization, single crystal heat-resistant alloy, hardening phase, natural composite structure, additive technology.

THE RESEARCH OF THE POSSIBILITY OF HIGH ENTROPY ALLOY VNbMoTaW PRODUCTION BY MIXING ELEMENTARY POWDERS WITH FURTHER HYBRID SPARK PLASMA SINTERING

The paper considers the possibility of synthesis of a high-entropy alloy VNbMoTaW by the method of hybrid spark plasma sintering from an equiatomic mixture of elemental powders obtained by dry mixing. The microstructure was examined by scanning electron microscopy, the X-ray microscopic analysis was used to evaluate the elemental composition, and the microhardness of the resulting phases was studied by microdurometric hardness testing. It has been determined that in spite of the influence of sintering temperature on the diffusion processes, a significant unevenness of structure formation is manifested.

Keywords: high entropy alloy, spark plasma sintering, powder metallurgy, diffusion, sintering with liquid phases.

INFLUENCE OF QUENCH RATE ON MICROSTRUCTURE AND MECHANICAL PROPERTIES OF NICKEL-BASED WROUGHT SUPERALLOY VZh175-ID

The influence of the quenching rate on the size of the secondary particles of the strengthening g¢-phase microstructure as well as on the mechanical properties of nickel-based superalloy VZh175-ID has been studied. It was shown, that cooling rate in the temperature range of up to 1000°C has significant effect on mean size of the secondary γ¢-precipitates and their morphology during quenching. There was studied the relationship between the cooling rate, mean size of the secondary γ¢-precipitates and short- and long-term strength of VZh175-ID alloy. The required quenching rate is determined to achieve the desired level of properties: ≥1570 MPa, ≥1175 MPa, life time to rapture is more than 100 hours at temperature 650°C and tension σ=1050 MPa.

Keywords: Ni-based superalloy, quenching, cooling rate, gamma prime, mechanical properties, superalloy VZh175-ID

RESEARCH OF THE STRUCTURAL-PHASE COMPOSITION OF LASER WELD JOINT DEPENDING ON THE THERMAL PROCESSING OF THE ALUMINUM ALLOY V-1469

The effect of heat treatment on the structural-phase composition of a welded joint of the aluminum-lithium alloy V-1469 obtained by laser welding was studied. As a result it is shown that heat treatment of the base alloy leads to a change in the lattice parameters and crystal size. Complete heat treatment leads to the restoration of the structural characteristics of the alloy to the initial values. It is shown that the change in the strength of samples of alloy V-1469 after welding and heat treatment is not due to the absence or presence of impurity hardening intermetallide phases, but is due to the spatial distribution of these phases.

Keywords: laser welding, aluminum-lithium alloy, structural-phase composition, microstructure, heat treatment.

ELECTROSTATIC METHOD OF FORMING ULTRATHIN FIBERS OF REFRACTORY OXIDES

The paper discusses an innovative method of production of ultrafine fibers by electroforming from a free surface. The possibility of using the solutions used in traditional methods of production of high-temperature ceramic fibers is shown. The main parameters of the process are defined. Zero-defect ultrathin oxide fibers were obtained by high-temperature processing technology which is used for micron-sized material. A comparative analysis of fibers produced by various methods is conducted.

Keywords: electroforming, ultrathin fibers, microstructure, high-temperature processing, oxide high-temperature fibers, heat-shielding materials.

EVALUATION OF PROPERTIES OF GLASS-FIBRE-REINFORCED PLASTICS BASED ON EPOXYBISMALEIMIDE RESIN, PRODUCED BY DIFFERENT NON-AUTOCLAVE MOLDING TECHNIQUES

The polymer composite materials producers strive to reduce the labour intensity of production process and thus to reduce the final cost of the products. It leads to the refusal from using the traditional autoclave molding in favor of alternative technologies. At present there is a number of resins developed for certain non-autoclave moulding techniques. We find it promising to develop the binder on the basis of which it will be possible to produce the high-quality composite polymer materials by various formation techniques.

Keywords: polymer composite materials, resin, non-autoclave moulding

THERMAL RESISTANCE OF ELECTROLYTIC CHROMIUM COATINGS

The paper presents the results of a study of heat resistance of the chromium coatings obtained in different electrolytes of chromium plating, during cyclic heat treatment at 400, 650 and 800°C. The influence of high temperature effects on the degree of reduction of the microhardness of chromium platings has been studied and the critical temperature of its degradation has been determined. It is shown that the alloying of chrome-molybdenum coatings ensures high durability chrome-molybdenum coatings for temperature action up to 650°C. Metallographic investigations of the structure of the chromium coatings after their heat treatment at a temperature of 650°C during the complete testing cycle. The results of testing the heat resistance of chromium coatings by the gravimetric method are presented.

Keywords: chrome plating, chrome plating electrolyte, heat resistance, heat treatment, molybdenum compounds, adhesion, microhardness.

THE INFLUENCE OF SILICON TETRABORIDE ADDITIVES ON PROPERTIES OF HEAT-RESISTANT COATINGS FOR NICKEL ALLOYS PROTECTION

Silicon tetraboride SiB₄ is a promising material for use in composite high-temperature materials and coatings. The introduction of SiB₄ into the composition of erosion-resistant coatings for thermal protection of the orbital ship «Buran» made it possible to ensure their high erosion resistance, temperature resistance and reflectivity. The actual direction in the field of creation of high-temperature coatings is the development and research of heat-resistant coatings with additives of silicon tetraboride for the protection of heat-resistant nickel alloys.

Keywords: glass, silicon tetraboride, coating, heat-resistant nickel alloys, high-temperature gas corrosion, reaction curing.

RESEARCH OF INFLUENCE OF TECHNOLOGY FACTORS ON THERMAL CONDUCTIVITY OF CERAMIC CASTING MOLDS

Thermal conductivity thick heterogeneous by structure of materials of ceramic forms is determined by the laser flash method. There was measured the thermal diffusivity and apparent density of samples of 3 mm thickness received by a division of the samples of 6 mm thickness into two halves. The general thermal conductivity was calculated based on two-layer model using the earlier published data of heat capacity of corundum-based materials. The received results prove that impregnation by the hydrolyzed solution of ETS-40 ethyl silicate after roasting at 1150°С made for strengthening purpose has no influence on the thermal conductivity of the samples materials; the tests results show the significant effect on increase of the thermal conductivity for 18% at average with growth of roasting temperature (after bending test at 1600°С). More essential influence of high-porous structure of the outside layers on the general thermal conductivity of a ceramic form is determined.

Keywords: fire-resistant ceramic forms, heat capacity, thermal diffusivity, thermal conductivity, laser flash method, adiabatic calorimeter, two-layer model.
