STRUCTURAL CHARACTERISTICS OF MONOCRYSTALLINE CASTINGS AND MECHANICAL PROPERTIES OF NICKEL-BASED SUPERALLOYS WITH LOW RENIUM CONTENT Part 1

For a new nickel-based superalloy VZhL22 with 2 % by weight of Re, based on a complete factor experiment of the type 2ⁿ + 2n + 1 (where n=3 is the number of variable factors ‒ technological parameters of casting) data on the effect of the main technological parameters of directional solidification on the yield of suitable single-crystal castings, the angular deviation of the axial crystallographic orientation of a single-crystal, angular disorientation of crystallites, volume fractions of casting pores and eutectic γ'-phase secretions, and the parameter of the dendritic cell in the alloy castings were obtained. The results are summarized in the form of regression models.

OPTIMIZATION OF THE SURFACE HARDENING PARAMETERS FOR 12X18H10T STEEL PIPES USING A REGRESSION MODEL

During the operation of turbojet engines, the pipelines of the external systems are subject to fatigue failure caused by fretting corrosion. The article presents the results of developing a model describing the change in the resistance of 8×1 mm pipes made of 12X18H10T steel to fretting corrosion after various types of processing. It is shown that maximum resistance to fretting corrosion is achieved at: microhardness HV_0,025 = 2510 МPа, modified layer depth greater than 44 microns, average compressive residual stresses greater than 208,5 MPa and roughness, R_a less than 1,18 microns.

INFLUENCE OF SYNTHESIS PARAMETRES ON THE STRUCTURE FORMATION IN HIGH-NITROGEN CORROSION-RESISTANT STEEL

The article presents the results of analysis of the influence of selective laser melting (SLM) technological parameters on the formation of structure, level of porosity and on the complex of mechanical properties of samples made of high-nitrogen corrosion-resistant bearing steel. It was found that exceeding the optimal energy values in the SLM process leads to significant changes in the resulting microstructure of the material. Excessive increase in specific energy density causes overheating of the melt and the associated negative phenomena, including gas release and defect formation, while insufficient energy exposure leads to incomplete fusion of the powder material and the formation of a heterogeneous structure.

FEATURES OF THE PRODUCTION OF SEMI-FINISHED PRODUCTS FROM HEAT-RESISTANT NICKEL, TITANIUM AND ALUMINUM ALLOYS BY PRESSURE WELDING

The article analyzes a number of works describing the current state of manufacturing products by pressure welding from various structural materials used in the aviation industry. Based on this analysis, the necessary preparation stages of welded blanks were formed to obtain the required weld quality. The level of properties and the structure of the resulting joints satisfactorily meet the requirements for both titanium and aluminum alloys, as well as heat-resistant nickel alloys.

COMPARATIVE ANALYSIS OF MECHANICAL PROPERTIES OF THE MATERIAL OF VT6 ALLOY DISK FORGINGS, MANUFACTURED BY VARIOUS METHODS AND PRODUCTION CONDITIONS

The article presents the mechanical properties of VT6 alloy disk forgings manufactured under various production conditions with different heat treatment modes. The research results presented in the main part of the article were obtained in the initial period of work on the introduction of VT6 alloy for engine parts and were confirmed later during the certification of disk forging weighing up to 100 kg. A comparison of the mechanical properties of stampings of the same type made of VT6 and VT3-1 alloys is given. The discussion pays special attention to the factors leading to a decrease in the viscosity characteristics of the material.

INVESTIGATION OF THE RESISTANCE OF THERMOPLASTIC POLYURETHANE DURING THERMOOXIDATIVE AND THERMOCHEMICAL TREATMENT WITH DIETHYLENE GLYCOLE BY GEL PERMEATION CHROMATOGRAPHY AND MICROSTRUCTURAL ANALYSIS

The stability of thermoplastic polyurethane samples during high temperature processing has been evaluated. Material degradation during thermooxidative processing in air at 200 °C is well explained by the possible presence of residual amounts of 1,4-butanediol and its participation in the processes taking place. For quantitative data processing, a model was proposed that is suitable to describe the kinetics of polymer degradation during its thermochemical processing at 150 °C (R²= 0,9982); to assess its suitability at a higher processing temperature of 180 °C, more data is required.

The second part of the review examines the compositions and methods for obtaining photocurable polymer pre-ceramic compositions for the manufacture of ceramics using vat photopolymerization. The main types of photocurable organosilicon polymers, active diluents, photoinitiators, and special additives are considered. The mechanisms of radical and cationic photopolymerization of photocurable polymer pre-ceramic compositions are presented. The effect of filler addition into the composition on the properties of ceramics is indicated.

POSSIBILITY OF OBTAINING CERAMICS BASED ON REACTION-BOUND SILICON NITRIDE WITH ADJUSTABLE HARDNESS AND HIGH HEAT STRENGTH CHARACTERISTICS

The article presents the features of obtaining silicon nitride-boron nitride ceramics Si₃N₄‒BN as a result of the joint interaction of silicon and boron with nitrogen in the presence of nickel additives with the subsequent protection of ceramics from high-temperature oxidation by the formation of borosilicate glasses and a solid substitution solution Si‒B‒O‒N in the surface layer. Some high-temperature characteristics of ceramics, the results of tribological studies and the results of tests of samples and products are given.

EFFECT OF GADOLINIUM DOPING ON THE MAGNETIC PROPERTIES OF SINTERED Pr–Dy–Fe–Co–B MAGNETS

The dependence of the magnetic properties of sintered materials of the composition (Pr_1–z–xDy_xGd_z)_{12,55–12,81}(Fe_0,80Co_0,20)_balB_5,71–6,25 (x = 0,34–0,58; z = 0,11–0,33)on the gadolinium concentration and sintering temperature of 1120–1140 °C was studied. The temperature coefficient of induction was measured in the temperature range of 20–100 °C. Demagnetization curves (magnetization and induction) were measured using a vibrating sample magnetometer (VSM) at temperature of 20±5 °C. The temperature dependences of the magnetization in the temperature range of 300–600 K were revealed. about the article states the effect of gadolinium on the magnetic characteristics of sintered materials.

DEVELOPMENT AND PREDICTION OF PROPERTIES OF EPOXY COMPOSITIONS USING MACHINE LEARNING METHODS

The article analyzes the application of machine learning methods for the development of epoxy compositions with specified properties. Approaches to the formation of training data sets based on limited number of experiments are considered. Special attention is paid to the methods of active learning and Bayesian optimization methods, which allow efficient planning of experiments. Practical examples of using machine learning models for predicting the properties of developed compositions are given. The advantages of combining different machine learning methods for solving complex problems in materials science are shown.

INVESTIGATION OF THE COMPOSITION AND STRUCTURE OF A THERMAL INSULATION COATING BASED ON A POLYMER MATRIX AND HOLLOW MICROSPHERES

Liquid thermal insulation compositions based on a polymer matrix and the additions of gas filled or evacuated microspheres are considered, and the main prospects and scope of application of thin film thermal insulation material obtained from these liquid compositions is shown. The microstructure and X-ray spectral analysis of a typical thin-film thermal insulation coating and microspheres included in its composition were studied by pyrolytic gas chromate-mass spectrometry, the composition of the polymer component of the material was determined, and the structure of microspheres was studied by X-ray diffraction.

FEATURES OF PREPARATION AND CONDUCTING TESTS TO DETERMINE THE TRANSVERSE TENSILE STRENGTH OF SAMPLES OF LAMINATED CARBON FIBER REINFORCED PLASTICS

The article presents the features of manufacturing, preparation for testing and testing of samples of layered carbon fiber reinforced plastics for transverse tensile strength. The features of laying out thick-walled plates and typical damage to the structure of the material during the manufacture of samples, as well as their influence of structural defects on the values obtained during testing are described. Differences in samples and their destruction are shown. At present, the Institute continues to improve the methods of testing layered carbon fiber reinforced plastics for the most complete description of the properties of PCM.
