EVALUATION OF RESISTANCE TO CONTACT-DEFORMATION IMPACT DURING INTENSIVE WEAR OF THE SURFACE OF CAST ENTROPY ALLOYS BASED ON THE Ni–Co–Cr SYSTEM

The tribological characteristics of entropy alloys based on the Ni–Co–Cr alloying system under contact-deformation impact under dry sliding friction conditions were studied. The results of the studies showed that the hardness of the equimass alloy is 10 % greater than equiatomic alloy, and the use of additional alloying increases the hardness of the equiatomic alloy by 20–45 %. The wear resistance of the alloys depends slightly on the hardness and, to a greater extent, on hardening due to the accumulation of subsurface defects.

DETERMINATION OF THE CAUSES OF THE FORMATION OF SURFACE CRACKS IN STAMPED PARTS MADE OF LOW-CARBON STEELS

A comprehensive study of parts made of low-carbon steel grades DC04 and DX54D was carried out in order to establish the causes of the formation of surface cracks using optical and electron microscopy, chemical analysis and metallography, the structure was assessed, the chemical composition, the structure of surface cracks and artificially obtained fractures of parts were studied. An X-ray spectral microanalysis of the surface of the opened cracks was carried out. A decrease in ductility due to contamination of the parts material with non-metallic inclusions has been established.

STUDY OF ISOTHERMAL PHASE TRANSFORMATIONS KINETICS IN HEAT-RESISTANT ALLOYS BASED ON GAMMA TITANIUM ALUMINIDE TiAl

An experimental investigation of structure evolution kinetics in heat-resistant intermetallic TiAl-based alloys of various classes has been accomplished under the conditions of high-temperature exposures in the temperature range 900–1300 °C and durations of 15–240 min. The Temperature–Time–Transformation diagrams (TTT-diagrams) have been constructed to summarize data on isothermal phase transformations in the studied alloys with initial structures after selective electron beam melting.

DEVELOPMENT OF A COLD-CURING POLYMER SYNTATIC FILLER WITH ENHANCED PHYSICO-MECHANICAL PROPERTIES

This paper presents the results of a study on the development of a cold-curing polymer syntactic filler composition for local strengthening of honeycomb panels, sealing end sections and filling technological voids of aircraft elements. About 100 compositions were studied, differing in components and their ratio in the system. The best composition based on test results was assigned the VPZ-25 brand. In terms of a number of properties, the developed material is at the same level or exceeds the characteristics of its foreign and domestic analogues.

METHODS FOR MEASURING AND IMPROVING THE CRACK RESISTANCE OF SILICON CARBIDE COMPOSITE MATERIALS

This literature review discusses methods for determining the fracture toughness of ceramic composite materials. The main methods for increasing crack growth resistance are given. Methods for determining mechanical properties using Vickers pyramid indentation, the three- and four-point bending method, and computer modeling of the crack growth process, including at elevated temperatures, are considered. The main disadvantages of each way of determining mechanical properties are presented.

ESTIMATION OF ELECTRICAL PROPERTIES DISTRIBUTION UNDER ELASTIC DEFORMATION OF THE CONTROL OBJECT BY EDDY CURRENT METHOD

The article deals with the possibility of estimating the distribution of electrical properties along the depth of the object using eddy current method of nondestructive testing. Experimental testing of stress-strain state estimation of titanium alloy plate at bending by means of transducer signal acquisition in a wide range of frequencies is carried out. The experimental data was analyzed using analytical calculation of the transducer signal. As a result of the studies, the relationship between mechanical stresses and electrical conductivity was established, and the possibility of effective control of the stress level by eddy current method was shown.

ASSESSMENT OF THE ADHESIVE STRENGTH OF THE FIBER–POLYMER MATRIX SYSTEM USING THE NONPARAMETRIC BOOTSTRAP METHOD

The article discusses the practical aspects of using the bootstrap method in micromechanics problems to assess the adhesive strength of the fiber–polymer matrix system. The article provides a detailed algorithm for constructing confidence intervals when calculating the bootstrap method. А comparative analysis of the interval estimation of experimental adhesive strength data using the nonparametric (bootstrap) method and a number of parametric methods was carried out. Based on the generated bootstrap samples, a histogram of the frequency distributions of the average values of the adhesive strength of the fiber–polymer matrix system is constructed.

The results of the study of color characteristics, surface profile and glass transition temperature of fluorepoxy (VE-46) and acrylstirol (AS-1115) coatings on the front and back surfaces of KMKU-2m.120 carbon fiber plastic exposed for 8 and 13 years in open conditions of a moderately warm climate were presented. Methods of colorimetry, profilometry and dynamic mechanical analysis were used to obtain information about the properties of coatings. Red enamel VE-46 and yellow enamel AS-1115 tuned out to be the most vulnerable to photochemical activity processes.
