Claddings, Coatings, and Surface Modification: Load Behavior of Hardfaced Sealing Surfaces of Fittings
Authors: Elsen-Humberg Stephan , Unterumsberger Fabian
Published: October 2024

High-pressure valves and fittings used in coal-fired 600/625 °C power plants are hardfaced for protection against wear and corrosion and to provide optimum sealing of the guides and seats. Stellite 6 and Stellite 21 are often used for hardfacing, which is carried out by build-up welding, usually in several layers. The valve materials are generally heat-resistant steels such as 10CrMo9-10 (1.7380), X20CrMoV1 (1.4922), or Grade 91 / Grade 92 (1.4903 / 1.4901). In recent years, cracks or delaminations have frequently occurred within the hardfaced layer. The influence of cycling operation is not well understood. Other essential factors are the chemical composition of the base material and of the filler metal; especially in terms of the resulting iron dilution during the deposition of the welding overlays. The research project was initiated to investigate the crack and delamination behavior and to understand the involved damage mechanisms. Thermostatic and cyclic exposure tests have shown that cracking is favored by the formation of brittle phases due to iron dilution from the substrate material during the manufacturing process. Recommendations for the welding process of hardfaced sealing surfaces of fittings were derived from the investigation results.

Published: October 2024

Diffusion bonding is a key manufacturing process for nucleation applications including compact heat exchangers. Accurately predicting the alloy's behavior during the diffusion bonding process presents challenges, primarily due to the intricate interplay of microstructural evolution and physical processes such as compressive loading, temperature history, and component migration. The current study develops a phase-field model designed to simulate the diffusion bonding in 316H stainless steel, a material with exceptional high-temperature strength, corrosion resistance and suitability to high-pressure conditions. Our model incorporates a multi-phase, multi-component framework that aligns the experimental observations with the grain growth and heterogeneous nucleation, where arbitrary external compressive load and temperature history are considered. The simulations focus on grain nucleation, growth, and microstructure evolutions across diffusion bonding line under a variety of temperature profiles, mechanical loads, and surface roughness conditions, mirroring experimental setups. Our model predicts consistent simulation results with experiments in terms of the grain size and distribution near the bonding area, offering a better understanding of the diffusion bonding mechanism and the manufacturing process for building reliable compact heat exchangers.
Creep-Fatigue Interaction Life and Prediction Model Based on Stress Relaxation Ratio of Nickel-Based Superalloy 617
Authors: WU Haili , SUN Lingen , MEI Linbo
Published: October 2024

Creep-fatigue tests strain-controlled with different strain amplitudes and different hold times at 725 were done on nickel-based alloy 617 as a typical candidate material for turbine rotor of advanced ultra-supercritical power plant. Stress relaxes during the hold time when the strain remains at the tensile peak. The analysis of the stress relaxation during different strain hold times shows that the ratio of the relaxation stress and the maximum stresses has strong correlation with strain amplitude and hold time. The failure life also has a certain dependence on the relaxation stress ratio. The failure life decreases and the relaxation stress ratio increases as the strain amplitude increases. The failure life decreases and the relaxation stress ratio increases as the hold time increases. Therefore the stress relaxation ratio was used as an intermediate variable to obtain the corresponding relationship model by establishing the relationship between the relaxation stress ratio and the strain and the relationship between the relaxation stress ratio and the failure life. This model can be used to predict the creep-fatigue interaction life more simply and directly.

Published: October 2024

The microstructural evolution of the MoSiBTiC alloy by rapid solidification and its effect on oxidation and mechanical properties were investigated in this study. A Mo-5Si-10B-10Ti-10C (at%) alloy was produced by a conventional arc-melting technique in an Ar atmosphere, and then it was rapidly solidified by tilt-casting into a rod-shaped copper hearth. Vickers hardness values increased drastically above 1000 Hv due to the microstructure refinement through rapid solidification. They rose from the center toward the outer surface, ranging from about 1100 to 1300 Hv. Interestingly, the oxidation resistance of the rapidly solidified MoSiBTiC alloy at 1100 °C was dramatically improved, probably due to the microstructure refinement effect with ultrafine grains. However, the fracture toughness value of the rapidly solidified MoSiBTiC alloy was about 8 MPa·m1/2, less than half of the cast and heat-treated MoSiBTiC alloy previously reported. Heat treatment and composition optimization will further improve the performance of the rapidly solidified MoSiBTiC alloy.

Authors: Zhang Shutong , Bridges Alex , Shingledecker John , Lolla Tapasvi , Acharya Rohan
Published: October 2024

This study investigates the influences of product chemistry and grain size on the high-temperature creep properties of 316 stainless steels by analyzing an extensive range of historical and modern literature data. The investigated 316 stainless steel creep property dataset, including more than 160 heats and 2,400 creep testing data, covers a wide spectrum of elemental compositions and product forms. To perform a prudent analysis of the creep property dataset, a statistical overview was first implemented to understand the data distribution relevant to data sources, chemistries, product forms, testing temperatures, and grain sizes. The creep data of 550°C, 600°C, 650°C, 700°C, and 750°C with ±10°C were grouped together, and the analytical study was performed on each sub dataset to investigate the temperature-specific creep performance. The creep strength was evaluated using the average stress ratio (ASR) between the experimental and predicted creep data of tested 316SS heats. The influence of composition and grain size on the creep strength ratio were evaluated using linear correlation analysis. Effects of specified and non-specified elements including C, N, and B were specifically investigated to understand their impacts on the creep strength with regards to the variation of creep temperature. In addition to the literature data, the most recent EPRI creep data of three commercial heats were used to validate the correlations from the historical creep property dataset.

Published: October 2024

An innovative additively manufactured gradient composite transition joint (AM-GCTJ) has been designed to join dissimilar metals, to address the pressing issue of premature failure observed in conventional dissimilar metal welds (DMWs) when subjected to increased cyclic operating conditions of fossil fuel power plants. The transition design, guided by computational modeling, developed a gradient composite material distribution, facilitating a smooth transition in material volume fraction and physical properties between different alloys. This innovative design seeks to alleviate structural challenges arising from distinct material properties, including high thermal stress and potential cracking issues resulting from the thermal expansion mismatch typically observed in conventional DMWs. In this study, we investigated the creep properties of transition joints comprising Grade 91 steel and 304 stainless steel through a combination of simulations and creep testing experiments. The implementation of a gradient composite design in the plate transition joint resulted in a significant enhancement of creep resistance when compared to the baseline conventional DMW. For instance, the creep rupture life of the transition joint was improved by > 400% in a wide range of temperature and stress testing conditions. Meanwhile, the failure location shifted to the base material of Grade 91 steel. Such enhancement can be primarily attributed to the strong mechanical constraint facilitated by the gradient composite design, which effectively reduced the stresses on the less creep-resistant alloy in the transition zone. Beyond examining plate joints, it is crucial to assess the deformation response of tubular transition joints under pressure loading and transient temperature conditions to substantiate and demonstrate the effectiveness of the design. The simulation results affirm that the tubular transition joint demonstrates superior resistance compared to its counterpart DMW when subjected to multiaxial stresses in tubular structures. In addition, optimization of the transition joint’s geometry dimensions has been conducted to diminish the accumulated deformation and enhance the service life. Lastly, the scalability and potential of the innovative transition joints for large-diameter pipe applications are addressed.
Enhancing English Conversational Skills in Dogme ELT Approach: A Self-Regulation Perspective
Authors: Gökmen Muhammed Fatih
Published: October 2024

Conversational skills in EFL contexts have perennially posed challenges for learners and teachers. This action research aimed to ameliorate the conversational skills of 72 first-grade ELT students within the ‘Speaking skills’ course by intervening with the principles of Dogme ELT. Inspired by self-regulation phrases, the methodology involved self-reports to analyse student needs, reflective journals to monitor their progress, and open-ended questionnaires to receive feedback on the intervention. The content analysis revealed conspicuous development in participants’ conversational proficiency and self-confidence, consequently overcoming linguistic and schooling obstacles. As for the pillars of Dogme ELT, the findings suggest that the paucity of conversational practice could be compensated with extensive in-class speaking practice, leading to more linguistic gains through the coverage of linguistic pointes emerging out of interactions. Technological tools integrated into interactions could effectively equip students with increased linguistic exposure. As per the research findings, educational implications and research suggestions were also elucidated.

First Investigations of Benthic Soft-walled Foraminifera and Gromiids (Protozoa) in the northwestern Sea of Japan
Authors: Sergeeva N. G. , Anikeeva O. V.
Published: October 2024

The taxonomic and quantitative composition of the meiobenthos, with an emphasis on foraminifera and gromiids were studied on the coast of Primorsky Region, northwestern part of the Sea of Japan, at water depths of 0.3–86.0 m. The Protozoa were evaluated for the first time in this region as a component of the meiobenthic communities. The protozoa are represented by four morpho-ecological groups: Ciliophora (free-moving and epibionts), both hard-shelled and soft-walled Foraminifera, and Cercozoa (class Gromiidea). The total abundance of the meiobenthos varied from 32 500 to 2 107 500 ind./m2. The presence of Protozoa was extremely variable. They were completely absent (station 62) and reached a maximum 155 000 ind./m2 (station 42). Among the protozoans, soft-walled foraminifers (SWF) and gromiids (GR) dominated. GRs accounted for up to 51–85% of the abundance of the total protozoa at some stations inPeter the Great Bay. At other stations, SWFs prevailed and reached 93–100% of the total protozoa. The most numerous hard-shelled (HSF) foraminifers and ciliates (CL) were obtained in the Vladimir Bay and at individual stations off the eastern coast of Primorsky Region. Brief descriptions with illustrations are given for 45 representatives of the SWF belonging to the families Allogromiidae and Saccamminidae, of which 22 of them are identified to the species or genus level, and 23 morphotypes are identified to the family level. The gromiid fauna is represented by six morphotypes.
Fluctuating Asymmetry of Some Characters in the Sakhalin Redfin Pseudaspius sachalinensis (Nikolskii, 1889) (Cypriniformes, Leuciscidae)
Authors: Romanov N. S.
Published: October 2024

Fluctuating asymmetry of seven characters was studied in five samples of the Sakhalin redfin Pseudaspius sachalinensis (Nikolskii, 1889). A comparison of these samples with each other showed that the ratio of variances of fluctuating asymmetry between characters corresponds in a majority of samples to the variance of the average values for these samples. The uniqueness of the sample from Bolshoi Chibisan Lake is indicated by the smallest number of agreements with other samples and the largest sum of variances for all characters. Clusterization of samples of the Sakhalin redfins in terms of variances of fluctuating asymmetry of all characters shows a division into two clusters: one includes samples from the Tym, Tumnin, Susuya, and Protochnaya rivers; and the other cluster includes a sample from the Bolshoi Chibisan Lake. For most indicators of fluctuating asymmetry, the Sakhalin redfin differs significantly from two other redfin species living in the same water bodies, this may indicate either species specificity or the influence of environmental factors at the initial stages of individual development of fish in the spawning sites.

Authors: Afanasyev D. F. , Abdullin Sh. R.
Published: October 2024

Geobotanical descriptions of Zostera communities were carried out in the eastern part of the Russian shelf of the Black and Azov seas. Based on the descriptions, the syntaxonomy of the class Zosteretea Pignatti 1953 is considered, taking into account the diversity of macrophytic algae. In total, 6 communities dominated by Zostera and Nanozostera were identified in the study area; all of them are described for the first time. The results obtained indicate that taking the occurrence of macrophytic algae into account in the floristic classification of communities dominated by Zostera and Nanozostera makes it possible to reliably identify several communities with specific composition, ecology, and location. It has been shown that the oligosaprobic marine sublittoral vegetation of sandy and silty–sandy sediments of the northeastern part of the Black and Azov seas is represented by widespread flowering plants of boreal origin and associated short-cycle species of cosmopolitan and subcosmopolitan macrophytic algae.

The Limits of the Use of Force in Contemporary Phase of International Relations
Authors: Pokštefl Josef
Published: October 2024

During the entire period of the society's existence in its class form, war is one of the means of promoting the interests of the ruling classes, it is one of the faces of their policy in the field of foreign relations. The ruling classes at a certain moment, when certain goals cannot be achieved in any other way than war, and when, according to their subjective assessment, there are favorable conditions for this, they resort to arms.
However, the use of force becomes an instrument of politics not only at the moment of its realization, but also as a potential possibility of realization. The threat of force may be enough for the respective state to achieve its foreign political goal. Clausewitz's well-known thesis defines this phenomenon as declaring war to be the continuation of politics by other means. Attempts to legally regulate this social phenomenon, attempts to limit and then prohibit the use of force in international relations are made after the world wolf. While attempts to create material obstacles to the use of force end in failure - see the failure of negotiations on disarmament - in the area of ​​legal regulation, the hastily signed.

Dozens of friendly and less friendly, scholarly and popular books have been written about the person of General Charles de Gaulle, describing de Gaulle himself and the so-called Gaullism to varying degrees. The inspiration for these books is usually the same as that mentioned by Ján Cierny for his current book General: the modern development of France cannot be imagined without this personality, who is also extremely interesting, complex, contradictory and attractive. However, the book "The General" wants to contribute to the understanding and closer knowledge of this leading personality of today's France and the saintly statesman in its own specific form.

The impact of artificial intelligence on creative industries: Freelancers’ anxieties and concerns
Authors: Strebkov D. O.
Published: October 2024

The article examines the impact of the rapid development of artificial intelligence (AI) technologies on the creative industries and the concerns of workers in this field regarding the potential deterioration of their working conditions and displacement from the labor market. The aim of the study is to identify the degree of concern among freelancers engaged in intellectual and creative professions regarding competition with AI and to assess their perception of AI’s current capabilities in making creative content. The empirical basis was provided by online survey data of 778 Russian freelancers receiving jobs through the Freelance.ru digital platform, conducted in spring 2024. It was found that many respondents are already actively using AI in their work. The majority of freelancers note AI’s high current capabilities in creating texts, images, translation, and other areas, and more than a third believe that in the coming years AI will be able to do their typical work as well or even better than they do it themselves. Those who were least likely to experience concerns about their future were individuals who had been trained in AI, used it to perform job tasks, satisfied with their work, and had a high level of income, i.e., generally had a stable position in the labor market. Despite the concerns of some workers, the development of AI opens up new opportunities for the creative industries; however, regular monitoring of the situation is required to develop measures to adapt the labor market.
General equilibrium: Theory and reality
Authors: Chigrin A. D.
Published: October 2024

The General Equilibrium Theory (GET) remains the cornerstone of the foundation of economic science. It is associated with the concept of the economy as a self-regulating system. However, its widespread application in economic analysis has not been observed. The theory does not allow one to find out the equilibrium point, a deviation and the relative direction of motion. The theoretical and practical value of such a theory is not obvious. The analysis of causal links underlying the GET does not give confidence in their sustainability, which deprives it of an empirical basis. Meanwhile, the classics described the basic mechanisms of self-regulation and defined the criterion of equilibrium, but the results were not formalized into a coherent theory. The equilibrium conditions of the classical and neoclassical approaches partially coincide. An example of the application of classical criteria is the analysis of some ambiguously interpreted problems. Against the backdrop of the uncertainty of the conclusions of the mainstream, classical approach gives a fundamentally different, dynamic and non-equilibrium picture of economic phenomena.

Authors: Ivashkovskaya I. V. , Makeeva E. Y. , Popov K. A.
Published: October 2024

Achievement of the UN Sustainable Development Goals at global and national levels is possible only in case of successful implementation of ESG principles in corporate strategies, meaning development of corporate environmental responsibility, social responsibility, high quality and transparency of corporate governance. Characteristics of board of directors as a superior corporate governance body are among the key determinants of corporate ESG transformation. This research includes comparative analysis of board composition and human capital characteristics in the largest Russian public non-financial companies, qualified as “leaders” and “outsiders” in terms of ESG transformation basing on corporate ESG rankings by RAEX Europe. According to obtained results, companies with higher ESG rankings are characterized by higher level of board’s independence and national diversity. Moreover, higher presence of independent directors with academic degrees and diversified educational majors in “leading” companies is proved. Finally, significant difference in board members’ professional experience is identified for companies from different ESG ranking clusters. These results not only broaden an evidence on board role inц corporate ESG transformation, but also are relevant in the context of considerable changes of corporate governance composition in large Russian companies in 2022 and 2023 years.
Economic ideology: Versions of the concept’s acceptations and application
Authors: Tambovtsev V. L.
Published: October 2024

Economy is one of the basic systems of human being, and economic concepts are used in various sciences, sometimes in unexpected combinations. One of these is the concept of economic ideology, used for quite a long time, but most widely in recent decades, and in various meanings. At the same time, its actual economic studies are rare, so that in fact it is used in political science, sociology and psychology. This discrepancy defines the objectives of the article: to analyze the main practices of using the concept of economic ideology and to propose a way to organize them, or propose a typology, based on which it would be possible to identify the directions of economic analysis of this concept. Such studies would allow us to develop the study of the subjective information, in particular beliefs, impact on economic decision-making.

The importance of human potential as a factor and criterion of socio-economic development
Authors: Kolganov Andrey I.
Published: October 2024

The importance of human potential as a factor of economic development was long recognized in economics. It proposed an interpretation of the economic realization of this role in the form of “human capital”. However, there are significant doubts about both the theoretical correctness of such an interpretation and its empirical validity. In addition, the concept of “human capital” significantly diminishes the role of human potential in production. To better assess this role, it is necessary to turn to the study of how human potential realizes itself in creative activity. The economic appropriation of the results of this creative activity brings additional income, which takes the form of intellectual rent. However, the capitalist form of appropriation of the results of the use of human creative potential limits the possibilities of its complete deployment and application. Moreover, the results of creative activity often take the form of false, illusory benefits, and even turn against human development. In order to ensure a better social effect of the use of human potential, it is necessary to find forms of support its development that will better correspond to its internal content. The peculiarity of creative activity, which consists in the fact that it acts not only as a means of achieving any goals, but also as an end in itself, allows the widest opportunities for the use of human potential if you provide each person with conditions for the complete development and application of his abilities. To achieve this, it is necessary to ensure priority development of the areas of formation and development of human potential (education, health care, science and culture) and true equality of the opportunities for the development of the abilities in each person, which will create the best possible base for the use of national human potential. Possible ways to solve these problems may be: 1) the implementation a policy of state paternalism and expand the production of so-called patronized goods, and 2) the gradual mitigation of the alienation of man from ownership and management in the economy, which requires the search for a partial compromise between the interests of employers and employees.
