The effect of chromium content on phase transformations in low-carbon high-strength steel for shipbuilding has been studied. Under industrial conditions, two rolled sheets 50 mm thick were manufactured from steel with a chromium content of 1.08% and 0.42% using hot rolling technology, followed by furnace hardening and high-temperature tempering, standard mechanical properties and performance characteristics were determined. With the help of optical and transmission electron microscopy, the structural features of steel were revealed.

The results of optimizing the technological modes of deposition of titanium coatings by the microplasma method are presented in order to identify the most productive one. Variable values of the current strength of the electric arc, the flow rates of the plasma-forming and transporting gases were used as variable parameters. The sputtering material was PTOM-1 grade titanium powder of various fractional compositions: 20–32, 32–40, and 40–71 µm. A series of experiments was carried out on a combination of a number of factors. The following factors were considered: a coating thickness of at least 200 μm, the exclusion of sintering of the sprayed powder in the channels of the plasma torch, low porosity of the coating (no more than 5%), a tight fit of the coating to the substrate, and the exclusion of delamination of the coating during mechanical processing. As a result, the most optimal modes of coating deposition were identified. For coatings with the lowest porosity (from 1.0 to 1.9%), when all the above indicators were achieved, the morphology and microhardness were studied. According to the SEM microimages of transverse sections, it was determined that the coatings adhere tightly to the substrate material, there are no areas with delamination of the coating, and the microhardness of the coatings is in the range of 685–744 HV.

The effect of heat treatment on the structure and properties of a new weldable heat-resistant alloy based on Ni–Fe–Co–Nb–Ti–Тa with a low coefficient of thermal expansion for parts of gas turbine engines was studied. The stability of the intermetallic globular phase, the features of precipitation of lamellar particles during annealing after quenching were studied. It is shown that the structure formed during heat treatment with nanosized cuboid and rounded particles of the γ′-phase, as well as with a small amount of lamellar η-phase precipitates along the grain boundaries, provides a high set of properties and excellence heat-resistance in comparison with iron-nickel commercial alloys of a similar purpose. With uniform precipitation of the γ′-phase higher tensile strength are achieved.

Samples of Mg–Zn–Al layered double hydroxide (LDH) have been synthesized by solid-phase interaction of Mg, Zn, and Al crystalline hydrates with (NH4)2CO3, and then studied by chemical, X-ray phase analysis, as well as by Brunauer–Emmett–Teller (BET) and Barrett–Joyner–Halenda (BJH) methods. The paper presents results of studies of structural and surface properties (specific surface area and volume of pores, distribution of pores by their diameter). It was found that an increase in the degree of substitution of Mg by Zn leads to an increase in the specific surface area and the specific volume of samples. At the same time, the distribution of mesopores has a polymodal character with a predominance of pores having dpor = 3–4 and 25–50 nm. It was found that the substitution of Mg for Zn in the composition of layered double hydroxides leads not only to an increase in the specific capacity of the monomolecular layer of LDH, but also to a stronger interaction of adsorbate (nitrogen) with their surface.

The paper studies structural transformations of the brazing seam and fillet of the T-joints formed during the diffusion brazing of the titanium alloy VT6S with filler alloy of the Ti–Cu–Ni–Zr system. The soaking time during brazing under the designed temperature is regarded as one of the most important processing terms. It is shown that the satisfactory level of the mechanical properties of the joints could be achieved at the proper technological parameters that provide removal of any alloying additions from the brazing seam as well as the minimum fillet size. The lamellar structure of the base titanium alloy could be recommended as the most desirable for the diffusion of brazed joints.

The results of the study of tin-bearing middlings are presented. The mineralogical composition obtained by micro-X-ray diffraction analysis was determined and thermodynamic modeling, using the software package Thermo-Calc, was carried out. The aim of this work was a comprehensive study of the interaction of arsenopyrite and cassiterite with salts of alkali earth metals and the search for the optimum composition and ratio of salts for the decomposition of arsenopyrite into separate easily removable components. With the help of these results further work on the development of a complex technique for the selective separation of arsenopyrite and cassiterite and the extraction of tin and associated metals from these middlings is relevant.

The effect of calcium consumption during out-of-furnace processing and its content in the finished metal on the quality of sheet steel grade 10KhSND, obtained from continuously cast slabs, has been studied. The research is based on the results of evaluating the macrostructure of slabs obtained from a continuously cast billet, as well as after testing the finished metal to determine impact strength, contamination with non-metallic inclusions, and ductile-brittle transition temperature. The paper analyzes the effect of consumption and calcium content in the metal.

The effect of the homogenization annealing duration on the critical brittle temperature of 15Kh2MFA-A vessel reactor steel has been studied. The criterion for calculating the duration of the annealing is determined – this is the total duration of heating of the ingot and forging before the first and second removals. It is shown that in order to achieve Тк0 not less than minus 50°С, a total specific exposure at a temperature of 1220±20°С of not less than 2.5 min/mm of section is required.

The paper presents the results of structural studies of ring specimens made of the 42XNM alloy after irradiation as part of the control and protection system of the VVER-1000 reactor to a damaging dose of ~12 dpa at a temperature of ~350°C and subsequent isothermal annealings in the temperature range of 400– 1150°C (heating and holding for ~2 h). It is shown that during long-term isothermal annealing, a change in the phase composition of the alloy is observed, dislocation structures and grain-boundary segregations are annealed, and porosity evolves. It has been confirmed that decrease in the plastic properties of the 42XNM alloy after irradiation and subsequent isothermal annealing in the temperature range of 400–1000°C could be explained by the formation of precipitates of the second phases (zones of discontinuous decomposition of the solid solution with the release of α-Cr particles along the grain boundaries) and pores at the grain boundaries.
