A study was made to analyze the rotational friction welding weldability of homogeneous and heterogeneous combinations of semi-finished products of nickel superalloy VZh159. Welded joints of cast semi-finished products in a homogeneous combination and cast semi-finished products with deformed ones were obtained. To select the optimal technological parameters, the values of the static bending angle of the samples obtained without hardening heat treatment were determined. Welded joints obtained at the selected optimal technological parameters and with hardening heat treatment after welding were investigated to determine the mechanical properties and structural features.

A review of the basics of modern thermo-magnetic and spin-polarization laser magneto-optical information recording technologies is presented. Alloys based on rare-earth (RE) and transition (TM) metals, due to the high degree of homogeneity of their magnetic and optical properties, have found practical application in superdense magneto-optical recordings. Discusses the principles and mechanism of magneto-optical recording and storage of information in thin RE–TM films. The magneto-optical characteristics for polycrystalline and amorphous alloys are compared depending on the film thickness, composition, and other structural parameters. The advantages of Gd–Fe–Co alloys for use in ultrafast optical magnetization reversal storage devices are formulated.

One of the important properties of benzoxazines as a class of polymers is their high chemical compatibility with various resins. In the present work compositions based on benzoxazine monomer and epoxy resins of various structures were obtained. Their rheological characteristics in special dynamic viscosity at different temperatures and profiles in dynamic mode were determinated. Water absorption and glass transition temperature of polymer matrix samples were investigated. Conclusions about modification of benzoxazine monomers with epoxy resins have been made.

The paper gives an idea of the processes taking place in the epoxy adhesive system during its curing. Kinetics of curing of thermosetting component of adhesive system by DSC method is investigated. A kinetic model of curing is proposed and experimentally confirmed. The dependence of the glass transition temperature on the degree of curing was determined experimentally. The analysis of the obtained experimental data is carried out and the diagram of isothermal transformations (TTT-diagram) of the studied composition is constructed. Isoconversion curves are applied to the resulting curve, which can be used to predict the storage time of the adhesive composition.

In the present study, metal matrix composite (MMC) material based on the aluminum alloy AD31 containing 20 vol. % silicon carbide was obtained by powder technology using mechanical alloying followed by hot pressing. Studies of the formation of the composite granules structure during the mechanical alloying process have been carried out. Samples of a monolithic composite material were produced for measuring density and carrying out strength tests. Tests of produced samples were carried out and the values of the MMC density and strength characteristics at room temperature were determined.

Presents the results of studies of prepregs and carbon plastics, in the manufacture of which oligomeric benzoxazines with different ratios of mono and diamines in the system were used as binders: this class of polymer resins combines the best properties of epoxy and phenol formaldehyde resins. The reaction activity of prepregs was studied, including after long-term storage, and the properties of carbon plastics. An increase in the amount of diamine allows one to increase the glass transition temperature from 151 to 220 °C, which leads to an increase in the heat resistance of the material. CFRPs based on oligomeric benzoxazines have a sufficiently high level of strength properties and retain at least 80% of their mechanical properties at elevated test temperatures; have low water and moisture absorption and are resistant to moisture.

In this work, a review of the cemented carbides alloys of the WC–Co system is carried out. The cemented carbides of the WC–Co system are mass used in various industries, for example, as tools. The characteristic of materials is given depending on the size of structural components. The features of obtaining starting materials for obtaining a powder mixture are considered. Attention is paid to the features of compaction of powder mixtures and their subsequent sintering. The main problems arising in the preparation of fine-grained hard alloys are considered.

In the production of heat-resistant nickel alloy foundries, it is extremely important to control the contents of harmful impurities, especially sulfur. In this work, the determination of sulfur in nickel alloys by high resolution mass spectrometry with a glow discharge, which eliminates spectral interference, is carried out. The selection of analysis conditions is given. The correctness of the results is confirmed by the analysis of certified standard samples of nickel alloys. The sulfur detection limits are 0,000003% by mass. The range of determined concentrations is 0,000016–0,0401% by mass, and the relative standard deviation does not exceed 0,05.

In this work, the technological characteristics of model compositions for injection molding are evaluated by studying their rheological behavior when changing the content of the main components of the model composition. The influence of the ratios in «paraffin/petroleum resin» and «sevilen/polyethylene wax vapor», and also on the properties of polyvinyl alcohol used as solid filler on the rheology of model compositions of experimental compounds is considered. Based on the results, it was suggested that the ratio of petroleum resin and paraffin should be 2/1, the ratio of polyethylene wax and sevilen 1/1 respectively.
