Abstract
The results of an experimental study regarding the influence of the material and calibration of the piercing mill mandrel on its wear resistance upon piercing workpieces made of steel 20Kh13 have been presented. To carry out the study, mandrels made of four grades of steel (4Kh5MFS, 5Kh3V3MFS, 20Kh2N4A, 3Kh3M3F) and two types of calibrations have been used: with a smooth working surface and a specially designed one that ensures fractional deformation in the source during piercing by applying a periodic variable profile to the working surface, representing longitudinal grooves. The effectiveness of using a mandrel with longitudinal recesses on the working surface to increase its durability is confirmed by the results of computer modeling using the finite element method in the QForm 2D/3D software product. The experimental study was carried out on a two-roll piercing screw rolling mill MISIS-130D with barrel-shaped rolls and a guide tool in the form of fixed rulers. The durability of the mandrel was assessed by visual inspection of the quality of the working surface and by determining the change in mass after each pass upon piercing workpieces made of steel 20Kh13. According to the results of the work, it was found that the wear of all types of mandrels is predominantly adhesive in nature (there are traces of metal adhesion and tearing out on the mandrels). The best results in terms of durability were shown by a mandrel made of steel 20Kh2N4A.

Abstract
The discrete control method of the mechanical properties and structure during heat treatment of grade 50 steel vessels with residual heating after thermomechanical treatment on the rolling-press line of the Bogorodsk branch of NPO Pribor is developed and studied. The advantages and disadvantages of cooling media are considered depending on the conditions of heat absorption. The influence of various compositions and concentrations of polymer aqueous solutions and mineral oil on the properties and structure of deformed vessels under cooling are studied. The possibility of varying the cooling media to regulate the cooling rate and properties of rolled products is shown. Analysis of the obtained research results makes it possible to establish collective patterns between the cooling rate, the resulting microstructure and the mechanical properties of grade 50 steel vessels at the outlet of the rolling-press line of the Bogorodsk branch of NPO Pribor.

Abstract
The operation of the cold pipe rolling mill of JSC Sinarskii Pipe Plant is considered. A solution was proposed to modernize the main drive of the mill by forming four subsystems: the main drive, which ensures the movement of the main mechanism (stand) during pipe rolling; drive of working feed of the workpiece by 15–30 mm when the stand passes the extreme positions; front chuck rotation drive; rod chuck rotation drive, which ensures the workpiece rotation by 30 degrees. A mechatronic system was developed that covers each of the subsystems and allows for overall control. A mathematical model of the control loop for technological coordinates of the drive was developed and studied. The developed mechatronic system will improve the productivity of the cold rolling mill and the reliability of its operation while reducing the influence of mechanical loads.

Abstract
The influence of the cadmium plating process from various types of electrolytes and the corrosion resistance of cadmium coatings on the strength characteristics of 60S2A steel were investigated. The research results showed that, contrary to the established opinion that the ammonium chloride electrolyte of cadmium plating has a minimal tendency to hydrogenation, it is practically absent in the ammonium sulfate electrolyte, which makes it possible to eliminate the energy-intensive (and sometimes even dangerous) operation of heat treatment of products after applying a cadmium coating. The corrosion resistance of cadmium coatings is highest for ammonium sulfate electrolytes, both with and without chromate passivation. The use of TsKN additives in all three types of electrolytes leads to a noticeable increase in the corrosion resistance of cadmium coatings.

Abstract
Several copper alloys with the addition of Zn and Sn are taken for the study. In order to determine the effect of severe plastic deformation (SPD) on microstructure formation, these alloys are subjected to severe plastic deformation on a Gleeble-3800 thermomechanical simulator. The study uses a special case of 3D forging—2D forging, using a MaxStrain multi-axis deformation module. Two modes are developed for processing: 10 deformation cycles (20 impacts) at room temperature with a total degree of deformation greater than 7; 20 deformation cycles (40 impacts) at room temperature with a total degree of deformation greater than 17. The results of the analysis of the microstructure of copper alloys after physical modeling are presented in the study.

Abstract
The structure, phase composition, mechanical and magnetic properties of deformable hard magnetic Fe–30Cr–20Co–2Mo alloy obtained by sintering (1400°C, 240 min) of elemental powder compacts. The effect of quenching (1300°C, water) and stepwise heat treatment on the structure, mechanical properties during compression and magnetic characteristics of the samples is established. In the samples after sintering, a high proportion of the brittle sigma phase is recorded (~47%). The yield strength of such samples under compression is 1330 MPa with a brittle nature of fracture. After quenching, the yield strength decreases to 607 MPa, but the ductility of the samples increases. The increase in the samples ductility after quenching is associated with the fixation of the ferrite phase in the structure with a small amount of chromium oxides. After stepwise heat treatment, the ductility remains close to the ductility of quenched samples, but the yield strength increases to 1190 MPa. The Portevin–Le Chatelier effect is observed on such samples. Structural changes in the alloy during stepwise heat treatment lead to the appearance of technically suitable magnetic properties (residual induction 0.83 T, coercive force 56.4 kA/m, magnetic product 16 kJ/m3).

Abstract
The results of studies of the elemental composition and wear resistance of coatings formed by plasma-electrolytic oxidation on aluminum alloys are presented. As a result of X-ray spectral analysis, the distribution of chemical elements was revealed, which makes it possible, to a certain extent, to judge the influence of the electrolyte used and the chemical composition of the oxidized alloy on the elemental composition of the oxide-ceramic coating. It was established that the wear rate of coatings is 4.3–4.8 times lower than that of aluminum alloys without coatings. Electrolyte composition for plasma-electrolytic oxidation of aluminum alloys was recommended.
