RESEARCH OF DIFFERENT HEAT TREATMENT MODES INFLUENCE ON PROPERTIES OF SEMI-FINISHED PRODUCTS AND WELDED JOINTS FROM TITANIUM ALLOY ВТ22М

The article presents the results of a study of the various heat treatment effects on the semi-finished and welded joints properties, made by electron-beam welding made of alloy VT22M. In addition to the traditional used step mode for forgings made of VT22M, the possibility of using heat treatment for strength σв≥1200 MPa and heat treatment with heating above the α⇄β transition temperature has been considered. The effect of vacuum heat treatment by stepped mode and the mode with heating above the transition temperature α ⇄ β on the properties of welded joints and the semi-finished has been investigated. Also the properties of welded joints have been investigated when using an insert made of alloy VT1-0.

Keywords: high-strength titanium alloys, deformation, mechanical properties, heat treatment, microstructure, fracture toughness, electron-beam welding.

INFLUENCE OF THE LEAKAGE VALUE IN THE VACUUM CHAMBER ON THE PARAMETERS OF REACTIVE MAGNETRON DISCHARGE AND PROPERTIES OF TITANIUM OXIDE COATINGS

The influence of the magnitude of leakage in the vacuum chamber on the discharge voltage during reactive magnetron sputtering of titanium oxide coatings on the PET film, the deposition rate and refractive index of the coating are investigated. The article shows that the initial value of leakage in the vacuum chamber can have a significant impact on the process parameters of reactive magnetron sputtering, and optical properties of the titanium oxide coating. It is found that in case of reducing the initial quantity of leakage in the vacuum chamber prior to applying the titanium oxide coating, the mean value of the discharge voltage of the magnetron decreases, while the reactive magnetron deposition rate and refractive index of the coating titanium oxide increase.

Keywords: magnetron reactive deposition, optical coating, titanium oxide, polyethyleneterephthalate, magnetron sputtering parameters, leakage into the vacuum chamber.

RESEARCH OF THERMAL CONDUCTIVITY OF PRINTED CIRCUIT BOARDS BASED ON ALUMINUM SUBSTRATE AND ALUMINA DIELECTRIC

Printed circuit boards (PCB) based on aluminum substrate with dielectric layer are widely used for production of electronic devices with significant heat generation. The performance properties of the boards and the required elements of the cooling systems will depend on the thermophysical properties of both the board itself and its dielectric layer. This article describes the thermal conductivity of multilayer printed circuit boards coated with aluminum oxide. The dependence of the integral thermal conductivity on the thickness of the substrate and the number of coatings is shown. A technique for estimating the thermal conductivity of alumina coatings is presented.

Keywords: thermal conductivity, thermal resistance, alumina, coating, substrate, multilayer package, PCB.

DESTRUCTION FEATURES OF STEEL 20ХГСН2МФА-ВД DURING THE FRACTURE TOUGHNESS TEST

The article reviews the destruction features of specimens of steel 20ХГСН2МФА-ВД during the fracture tough-ness test. It has been found that the destruction of the samples with small thickness (10 mm) is conducted by the shift from shear stresses. The article analyzes the deviation of the fracture trajectory from the plane of initial fatigue cracks. It is shown that such development of cracks is due to the stress-strain state of the material at its top. In-creasing of the samples thickness changes the nature of destruction - a significant separation zone is formed. In the determination of fracture toughness on samples with a thickness of 50 mm takes place stepwise development of cracks. The bearing load of the samples of steel 20ХГСН2МФА-ВД does not change due to large areas of plastic deformation, inhibiting the destruction. Reducing of the test temperature to -70°C led to a macro-brittle fracture of 50 mm thick samples and a decrease in the fracture toughness.

Keywords: fracture toughness, shear, detachment, the trajectory of the crack, safe damage, stress-strain state, brittleness.

COMPARATIVE EVALUATION OF METHODS FOR THE DETERMINATION OF CORROSION AGGRESSIVITY OF THE ATMOSPHERE

The paper presents methods for monitoring and analyzing two aerochemical parameters of the atmosphere - the deposition rate from the atmosphere of chloride ions and sulfur dioxide - and the results of measurements during the year at eight climate stations. During determining the deposition of atmospheric sulfur dioxide, the «sulphate cup» method was tested, the dose-response functions were used to calculate the annual mass loss of standard metals for this method, and comparable values were obtained with the «sulphate plate» method in deter-mining the categories of corrosivity. The analysis of the samples on the sulfate content by turbidimetric method was carried out.

Keywords: aerochemical parameters, methods «wet candle» and «dry cloth», sulphate plate/cup/cylinder, turbidimetric analysis.

EXPERIENCE IN MEASURING THE THERMAL LINEAR EXPANSION COEFFICIENT OF COMBINED CORDS USING ORGANIC AND GLASS FIBERS

The paper presents the results of studies of the average temperature coefficient of linear expansion of combined cords made of organic material and glass fiber. Approaches are proposed to minimize the measurement error of thermal expansion of cords in the temperature range from -150 to +100°C. The effect of stresses on the test results of the average temperature coefficient of linear expansion of aramid and arimide fibers is shown. The dependence of the change in thermal expansion of organic filaments on the content of sulfuric acid in them is reflected.

Keywords: arimide fibers, aramid fibers, glass fibers, temperature coefficient of linear expansion, dilatometry, cord.

THE THERMAL STABILITY OF RARE-EARTH MAGNETS SUPPORTED BY MEANS OF THE MAGNETOCALORIC EFFECT

The possibility of stabilizing the working temperature of the magnet by means of cooling devices based on the magnetocaloric effect is considered. The results of magnetic hysteresis study obtained by the authors for MgO(111)/W(5 nm)/Ho(400 nm)/W(5 nm) samples are presented. The magnitude of the magnetocaloric effect is estimated by calculating the magnetic entropy. The obtained results are compared with modern works in the field of magnetic calorimetry and materials that are recognized as the most promising for the implementation of cooling cycles in a magnetic field. It was found that holmium films in the range of 120-140 K are applicable for the development of magneto-cooling devices on their basis.

Keywords: magneto calorometric effect, magnetic entropy, holmium, Curie temperature, direction of magnetization, the magnetic order, rare earth magnets.
