Using of High-Strength Protective Coatings, Reducing the Risk of Initiation and Development of SCC Defects

The article is devoted to the application of new methods of protection of trunk pipelines with defects of stress corrosion cracking. New anti-corrosion coatings will significantly reduce the stress level in the pipeline being repaired, preventing the development of SCC defects. © 2022 American Institute of Physics Inc..

Recommendations for the Repair of Gas Pipeline Sections Containing SCC Defects Up to 10% of the Pipe Wall Depth

The SCC problem remains discussed until now, despite 40 years of research. The approaches to SCC of scientific organizations to defects up to 10% deep are considered. The mechanism of development depending on soil pH is described. Measures are proposed taking into account the acidity of the soil. © 2022 American Institute of Physics Inc..

Совершенствование сбытовой деятельности предприятия как фактор повышения его конкурентоспособности

Работа предприятий в новых экономических условиях предполагает реструктурирование всех функциональных сфер деятельности хозяйствующих субъектов, но главным образом это касается сферы сбыта готовой продукции. Совершенствование сбытовой деятельности предприятия состоит в том, чтобы доводить товары до потребителя в том месте, в том количестве и такого качества, которые требуются, а также максимально использовать свои возможности для улучшения обслуживания покупателей

Оценка конкурентоспособности предприятия и разработка комплекса мероприятий по ее повышению

Конкуренция – один из значимых факторов, стимулирующих повышение эффективности функционирования предприятий и экономики страны в целом. Проблема конкурентоспособности товаров, предприятий, производств, стран – одна из самых актуальных и динамично развивающихся в мировой экономике

On the electric activity of superfluid systems

The Keldysh's theory of superfluidity of rarefied electron-hole gas is generalized to a case of possible pair polarizability. It was shown that inhomogeneity of the system leads to dipole moment which is proportional to the density gradient. The dipole moment appears also near boundaries of the system. It was determined that quantized vortices in a magnetic field carry a real electric charge. In He II at H=10 T and helium rotation velocity $10^2$ s$^{-1}$ the charge density is about $10^4e$ cm$^{-3}$, where $e$ is the electron charge.Comment: 5 pages V. 2: replaced incorrect g valu

A search for disordered (glassy) phase in solid 3He deformed in situ

A disordered (glassy) state has been searched in solid 3He deformed in the course of experiment employing precise measurements of pressure. The analysis of the temperature dependence of the crystal pressure measured at a constant volume shows that the main contribution to the pressure is made by the phonon subsystem, the influence of the disordered phase being very weak. Annealing of the deformed crystal does not affect this state. The results obtained differ greatly from the corresponding data for solid 4He measured in the region of supersolid effects where a pressure excessive in comparison to the phonon one was registered. The excess pressure had a quadratic dependence on temperature, which is typical of a disordered system. Absence of the excess pressure in solid 3He is unclear yet, some speculative interpretations are suggested.Comment: 9 pages, 4 figure

Fractographic Study of Fatigue Failure of a High-Pressure Turbine Rotor Blade

The paper presents the results of a factual study of the fracture surface of a high-pressure turbine rotor blade with a fatigue crack. The study of the fracture relief showed that on the fracture surface of the blade near the trailing edge there is a zone of brittle transcrystalline and intergranular fracture, surrounded by an intragranular fracture with a developed microrelief. Further crack growth in the direction of the leading edge was carried out by a fatigue mechanism. As a result, it was found that the main cause of blade failure is the formation and development of a fatigue crack in the direction from the trailing edge of the airfoil to the leading edge. © 2022 American Institute of Physics Inc..
