HEAT-RESISTANT COBALT-BASED ALLOYS

Cobalt-based alloys are widely used for manufacturing of various components of gas turbine engines and gas turbines such as vanes and combustion chambers both in wrought state and as cast parts. They have been designed for improving the heat resistance due to solid solution and carbide-strengthening mechanisms. In order to obtain satisfactory oxidation resistance and hot corrosion resistance cobalt-based alloys are doped with sufficient amount of chromium (above 15 % wt.). Recently additive manufacturing has started to use cobalt-based alloys. The paper considers the features of the structure of high-temperature cobalt-based alloys and their application in various branches of industry.

Keywords: cobalt-based alloy, solid-solution hardening, carbide hardening, heat resistance, corrosion resistance, additive manufacturing.

AUTOCLAVE MOLDING OF LOWER WING PANEL SKINS FROM 1441 ALLOY PLATES

The paper considers the main features of the process of autoclave molding of complex geometric shape parts from plates of medium-strength alloy 1441, combined with aging to the state of T11 heat treatment. The article provides the results of modeling of the autoclave molding process of skin fragments of the lower wing panel made of 1441 alloy, and the temperature-time parameters of this process determined during the research. The paper generalizes the results of examination of mechanical and corrosion characteristics of the fragments of the lower wing panel. The possibility of obtaining high accuracy of geometry of complex shaped elements while ensuring uniformity of characteristics in the entire area of parts is shown.

Keywords: autoclave molding method, modeling, stress-strain state, plate, 1441 alloy, wing skin.

SYNTHESIS AND STUDY OF COPOLYMERS OF ETHYLENE WITH HEXENE-1, MODIFIED WITH FINISHED NANOFIBERS-Al2O3 (NAFEN) WITH INCREASED RESISTANCE TO THERMAL OXIDATIVE DEGRADATION

Here we report the study on synthesis and characterization of nanocomposites obtained by in situ catalytic polymerization of ethylene and hexene-1 on metallocene catalyst in the presence of dispersed surface-functionalized -Al2O3 nanofibers (Nafen). It has been determined that surface treatment of Nafen nanofibers with organosilanes allows to obtain stable nanoscale dispersions under ultrasonication. It has been shown that nanocomposites based on copolymers of ethylene with hexene-1 demonstrate improved resistance to thermal oxidative degradation in comparison with nanocomposites based on copolymers of ethylene with propylene, while the influence of the silane chemistry on the mechanical characteristics in these nanocomposites is less pronounced. The best mechanical characteristics were achieved for nanocomposite with Nafen treated with trimethoxyvinylsilane. The melt flow index drop is observed after moderate heat treatment or combined temperature/humidity.

Keywords: polymer nanocomposites, ethylene copolymers, Al2O3 nanofibers, organosilane surface functionalization, thermooxidative degradation, mechanical properties, rheology.

NIOBIUM REINFORCED BY α-Al2O3 FIBERS Part 1. Two-Component Compositions

The paper reviews the results of development of a new class of high-temperature composites based on niobium and various types of reinforcers continuous monocrystalline fibers (MCF) α-Al2O3, with TiN, Mo, W barrier coatings, and with controlled (Si, Ti) and uncontrolled (O, C) impurities. The analysis of Nb–Si, Nb–C, Nb–O binary diagrams and Nb–Si–Ti, Nb–Fe–Ti ternary diagrams was performed, on the basis of which the matrix compositions were selected. The basis for the preparation of composites was the powder method of mechanical alloying of the mixture preparing, followed by its pressing together with α-Al2O3 MCF by spark plasma sintering (SPS) and further preparation of experimental samples. An analysis of the interaction of fibers with a matrix was carried out, where the matrix was Nb or system on the basis of the above mentioned binary or ternary diagrams.

Keywords: Nb matrix, α-Al2O3 monocrystalline fibers, TiN barrier coating, Mo barrier coating, W barrier coating, high-temperature bending strength.

STRUCTURAL AND MECHANICAL PROPERTIES OF A COMPOSITE MATERIAL BASED ON PARTIALLY STABILIZED ZIRCONIUM DIOXIDE DOPED WITH MAGNESIUM ALUMINATE SPINEL

Ceramic materials based on zirconia (ZrO2) are high-tech raw materials for structural products used in various fields of technology. ZrO2 has a wide range of application due to its unique strength characteristics, chemical resistance and fire resistance. However, the disadvantage of zirconium ceramics is low resistance to thermal shock, which limits its use in products functioning in conditions of frequent temperature changes. In this paper, we consider the possibility of increasing the resistance to thermal shock of ceramics based on zirconium dioxide, due to the introduction of an aluminum-magnesium spinel additive (MgAl2O4).

Keywords: zirconia, magnesium aluminate spinel, composite, heat-resistant ceramics, toughness ceramic, transformational hardening, polymorphism.

MAGNETIC PROPERTIES AND MAGNETIC STRIP DOMAINS IN MICRO STRIPES PrDyFeCoB

The article provides the analysis of PrDyFeCoB magnetic microstripes prepared by extracting material from a melt on a rotating cooling disk. The phases 2-14-1, 1-4-1 and 1-2, α-FeСо were verified in the samples. The division of a hysteresis loop into two strands shows that the coercive field of the α-FeСо phase (500–700 Oe) determines the width of the hysteresis loop near the zero field, while the coercive field of the 2-14-1 phase (10 kOe) corresponds to lateral hysteresis loops. The saturation magnetization increases by 25% with an increase in the disk rotation speed by 3 times together with correspondent acceleration of the cooling rate. This is due to the increase in the proportion of the soft magnetic phase α-FeCo and the increase in the proportion of the amorphous phase with a decrease in the proportion of the main magnetic phase 2-14-1. Strip domains and their dynamics during magnetization were detected using Kerr magneto-optical microscopy.

Keywords: ferromagnetic stripes, magnetic domain structure, strip domains, rare earth micromagnets, thin films, magnetic hysteresis.
