Effects of a New Thermo-mechanical Magnetic Heat Treatment Process on Creep Properties of High-Cr Ferritic Heat Resistant Steels
Authors: Okubo Hiroshi , Muneki Seiichi , Abe Fujio
Published: July 2024

Effect of thermomechanical and magnetic treatment on creep characteristics of advanced heat resistant ferritic steels for USC power plants has been investigated to explore fundamental guiding principles for improving creep rupture strength at elevated temperatures over 600°C. A model steel with a composition of Fe-0.08C-9Cr-3.3W-3Co-0.2V-0.05Nb-0.05N-0.005B-0.3Si-0.5Mn (in mass%) has been prepared by vacuum induction furnace. Creep tests at 650 °C and microstructural observations were performed on the thermomechanical and magnetic treated specimens after tempering. New thermomechanical treated samples without magnetic field showed some improvement in creep strength comparing with ordinarily normalized and tempered specimens. Further improvement was observed in the specimen that had been exposed to a magnetic field during transformation into the martensite. From the result of microstructural observation, it was found that the finely distributed precipitates such as MX and M23C6 caused this improvement. And it was suggested that the magnetic treatment at martensitic transformation increase the precipitation sites during tempering, resulting in increasing the amount and preventing the growth of the precipitates.

Authors: Shingledecker John P. , Swindeman Robert W. , Wu Quanyan , Vasudevan Vijay K.
Published: July 2024

The demand for higher efficiency and reduced emissions in coal-fired power boilers will result in the use of higher steam temperatures and pressures. A significant materials effort is required to reach a target steam condition of 760°C/35MPa. These new Ultrasupercritical (USC) units will require the use of nickel-based superalloys. Long-term creep strength will be a determining factor in achieving the highest possible steam conditions. To this end, the creep strength of commercially available (Haynes 230), modified/controlled chemistry (CCA617/Maгco 617), and new (INCONEL 740) alloys, including weldments, are being investigated at Oak Ridge National Laboratory (ORNL). Creep tests at ORNL show that the CCA617 provides a significant improvement in strength over the standard alloy 617 at 650°C to possibly 750°C. The strength of alloy 230 is well characterized, thus the testing on 230 has focused on specific specimen configurations for evaluating the high temperature behavior of weldments. Creep testing on INCONEL alloy 740 has shown good strengths (higher than 230 or CCA617) that may meet the target steam conditions. Microstructural analysis by electron microscopy on aged and tested material is being used to further understand the structure-properties relationship in these materials and determine long-term stability of the microstructures.

Authors: Makhele Lekala L. Z. , Reiners H. , Schubert F.
Published: July 2024

This study examines the deformation behavior of P92 steel (ferritic, 9% Cr) at high temperatures (600°C to 900°C) using isothermal hot tensile tests. Particular focus is placed on the stress-strain behavior around its alpha-gamma transition temperature (825°C). Additionally, fire accident simulation heating tests were conducted to assess the integrity of P92 beyond 650°C (relevant for short-term creep) and compare it to stainless steel 1.4404 (potential building material). Finally, microstructural analysis was performed on tested samples, revealing that the martensitic structure with characteristic laths was retained at temperatures up to 750°C.
Creep Deformation Behavior and Microstructure in High Boron Containing 9%Cr Ferritic Heat Resistant Steels
Authors: Semba H. , Abe F.
Published: July 2024

Tempered martensitic 9-12%Cr steels bearing tungsten, such as P92 and P122 showing higher creep rupture strength than the conventional steel P91, have been developed for thick section components in ultra-supercritical (USC) boilers. However, their creep strength is not sufficient for applying at the steam condition of 650°C/35MPa or above, which is a recent target condition in order to increase plant efficiency. The research and development project in NIMS on advanced high-Cr steels which can be applied at the steam condition of 650°C/35MPa as boiler components with large diameter and thick section has been carried out since 1997. In this project, it has been revealed that the addition of boron more than 0.01 mass% to the 0.08C-9Cr- 3W-3Co-V,Nb-<0.00ЗN steel remarkably improves creep strength. The boron enriched in M23C6 carbides near prior-austenite grain boundaries suppresses coarsening of these carbides during creep deformation, leading to excellent microstructural stability and creep strength. Further improvement of creep strength is achieved by the addition of appropriate amount of nitrogen which enhances precipitation of fine MX. Excess addition of nitrogen to the high-B containing steel reduces creep rupture lives and ductility. The highest creep strength is obtained in the 0.08C-9Cr-3W-3Co-0.2V-0.05Nb-0.0139B-0.0079N (mass%) steel, resulting in excellent creep strength in comparison with that of P92 and P122. This steel shows good creep ductility even in the long term. It is, therefore, concluded that this high-B bearing 9Cr-3W-3Co-V,Nb steel with the addition of nitrogen in the order of 0.008 mass% is the promising candidate which shows superior creep strength without impairing creep ductility for thick section components in the 650°C-USC plant.
Effect of Off-Normal Austenization on Creep Strength of Ferritic-Martensitic Steels
Authors: Totemeier T.C. , Simpson J.A.
Published: July 2024

The effect of a reduced-temperature austenization treatment on the microstructure and strength of two ferritic-martensitic steels was studied. Prototypic 9% and 12% Cr steels, modified 9Cr-1Mo (ASME T/P91) and Type 422 stainless (12Cr-1Mo-W-V), respectively, were austenized at the standard 1050°C and an off-normal 925°C, both followed by tempering at 760°C. The reduced austenization temperature was intended to simulate potential inadequate austenization during field construction of large structures. The microstructure, tensile behavior, and creep strength were characterized for both steels treated at each condition. While little change in microstructure was observed for the modified 9Cr-1Mo steel, the creep strength was reduced at higher temperatures and in long duration tests. The microstructure of the Type 422 stainless in the off-normal condition consisted of polygonized ferrite instead of tempered martensite. In this case the creep strength was reduced for short duration tests (less than ~1000 hr), but not for long duration tests. Slight reductions in tensile strength were observed at room temperature and elevated temperatures of 450,550, and 650°C.

Published: July 2024

The microstructures of two 9% chromium steels, P92 (30 ppm B) and B2 (100 ppm B), after heat treatment and after long-term creep deformation at 600°C were quantitatively investigated by means of transmission electron microscopy and boron trace autoradiography. The aim of the study was to show the boron distribution and identify the influence of boron on precipitation processes taking place in both steels during long-term creep exposure. The incorporation of boron into the M23C6 precipitates in both steels was demonstrated. In P92 steel (30 ppm B), boron was distributed preferentially on prior austenite grain boundaries and hardly visible on the sub-grain boundaries. In the steel B2 doped with 100 ppm B, boron was densely distributed on prior austenite grain- and sub-grain boundaries as well as within martensite laths. Quantitative TEM metallography and boron trace autoradiography investigation showed that boron retarded the growth of M23C6 by forming borocarbides M23 (C, B) 6, thereby significantly improving the creep rupture strength of boron doped 9% chromium steels.
Guidelines for the Assessment of Thermal Shock Cracking
Authors: Price JWH
Published: July 2024

This paper addresses thermal shock cracking, a critical damage mechanism for pressurized components, currently absent from design and fitness-for-purpose codes. It analyzes the crack growth mechanisms and proposes guidelines for designing vessels to resist thermal shock crack initiation and for assessing the significance of existing cracks discovered during service. Thermal shock crack growth is influenced by factors like shock severity, applied mechanical stress, and the corrosive environment. In service, cracks often arrest and pose minimal risk. This work explores a broader range of conditions, offering a less conservative approach compared to existing EPRI guidelines.
An Evaluation of the Steamside Oxidation of Candidate USC Materials at 650°C and 800°C
Authors: Sarver J. M. , Tanzosh J. M.
Published: July 2024

A collaborative program by the U.S. Department of Energy and Ohio Coal Development Office aims to identify new materials for ultrasupercritical (USC) coal power plants operating at significantly higher efficiencies. These USC plants require advanced ferritic alloys, austenitic steels, and nickel-based alloys with superior steamside oxidation resistance at high temperatures (up to 800°C). Initial tests on over 20 candidate materials exposed to flowing steam at 650°C for 4,000 hours show promise for nickel-based and austenitic alloys, while highlighting the dependence of oxidation resistance on chromium content for ferritic alloys. Notably, even within 9% Cr ferritic steels, varying compositions resulted in significantly different oxidation behaviors.

The topic of processing low-grade or low-quality bauxite is highly relevant in modern conditions due to the gradual depletion of high-quality bauxite reserves. Consequently, there is an increasing need to explore alternative sources of raw materials for aluminum production and its derivatives. Processing low-quality bauxite ores can become an effective solution, reducing dependence on limited high-quality resources and ensuring production stability in the long term. Such research has significant potential for developing technologies capable of optimizing aluminum production processes and enhancing its competitiveness in the global market. Bauxites from the Krasnooktyabrsky bauxite ore management with low aluminum oxide content (37 – 40% by mass) and a silicon module up to 2.0 are considered as potential blending materials for sintering bauxite in alumina production due to the depletion of high-quality bauxite reserves. This article presents the results of research on their processing into alumina at the Pavlodar Aluminum Plant. Laboratory and pilot-scale studies were conducted to assess the feasibility of using low-quality bauxite in alumina production and to determine the techno-economic indicators of processing. The research results confirmed the technological feasibility of processing depleted bauxites with a silicon module of 1.95 - 2.0 in the sintering section while maintaining the quality of sinter and extracting useful components. The maximum proportion of blending of depleted bauxites with the main bauxite was determined not to exceed 50%.

Published: July 2024

The article analyses theoretical and methodological approaches to the problem of forming children's socio-cultural values based on the principle of multidisciplinarity, from the point of view of the phenomenology of sociology, philosophy, axiology, cultural studies, pedagogy, axiopedagogy and psychology. The author also analyses scientific approaches to the definition of the term «socio-cultural values» and clarifies the essence of the phenomenon. The essence of the concept of socio-cultural values as the basic life meanings on which a person is based in everyday life, in relation to the surrounding reality and which enshrine specific features of a particular culture and model of social behaviour is substantiated. The methodological basis for the process of forming socio-cultural values in children is a combination of personal and activity, axiological, and participatory approaches. The structure of children's socio-cultural values is defined, their typology, criteria, indicators and levels of development are outlined. According to this, the structure of this phenomenon consists of: socio-cultural macro-values; socio-cultural meso-values; socio-cultural micro-values. The components of socio-cultural values are analysed in terms of the importance of the types of values: linguistic and value component, cognitive component, and pragmatic component.

Authors: Adeyemi Idris Babatunde , Tekdoğan Ömer Faruk
Published: July 2024

Islamic finance operates as an alternative system meeting the investment requirements of individuals adhering to Islamic beliefs. While conventional finance prioritizes stock exchanges facilitating small-scale investments, challenges arise for Muslims investing their savings in stocks due to potential conflicts between companies' activities and revenues and religious principles. This situation prompts Islamic scholars to deliberate on the permissibility of purchasing specific company stocks. Various scholars and Shariah boards have established precise criteria for determining the permissibility of buying a company's stocks, leading to the development of indexes aimed at identifying compliant companies. Shariah-compliant stocks or companies adhere to the principles of Shariah law, governing various life aspects, including financial and economic activities. This study investigates Shariah screening methods, exploring their rationale, foundations, and potential religious influences, particularly focusing on six prominent Islamic indices. The study investigates Shariah's justifications and motives behind these methods, discussing their evaluation through different standards. Despite scholars' varying opinions and evolving methodologies, the primary objective remains consistent: to facilitate halal income for Muslim investors while maintaining Islamic ethical principles in financial practices.

According to research on cutlery, it did not meet the bacteriological quality requirements for cleanliness because the disinfection process was not carried out. nfection process is necessary to enhance the cleanliness of cutlery, employing both chemical and natural methods. Lime zest is a natural ingredient that can be used for disinfection because it contains compounds such as alkaloids, tannins, steroids, triterpenoids, saponins, and flavonoids that are antibacterial by damaging cell membranes. The study's goal was to determine the efficacy of lime (Citrus amblycarpa) solution in improving the bacteriological quality of cutlery. This research is experimental, with a posttest-only control group design. The study included a total of 24 cutlery (plate) samples. We collected the data by examining the number of germs and Escherichia coli in each sample. Using Kruskal-Wallis, we analysed bacterial count data. Meanwhile, Escherichia coli could not be tested because all the samples were negative. The results showed that the cutlery (plate) before treatment did not contain Escherichia coli. By taking swab samples of the cutlery (plates), we found that the number of germs after disinfection treatment ranged from 1 to 33 colonies/cm2. Lime solution is ineffective at reducing the number of germs. It is recommended that the shop manager use running water and provide a place for draining and storing closed cutlery. Future researchers can conduct laboratory tests first to prove the effect of lime zest on Escherichia coli and carry out control treatments before concentration treatments.

Innovation und Verwaltungsreform
Authors: Friedländer Benjamin , Vedder Stefanie
Published: July 2024

In Staat und Verwaltung werden immer wieder Modernisierungslücken festgestellt, zum Beispiel im Umgang mit der digitalen Transformation, mit der Vernetzung von Akteuren, Organisationen und Sektoren oder in Bezug auf Themen wie Agilität oder Partizipation von Bürger:innen. Mit dem Schließen dieser Modernisierungslücken ist die Hoffnung verbunden, öffentliche Aufgaben effektiver, effizienter und transparenter zu erfüllen sowie die Problemlösungskapazitäten in Staat und Verwaltung zu erhöhen. Vor diesem Hintergrund wird in letzter Zeit wieder verstärkt darüber diskutiert, wie durch Public Sector Innovations neue Arbeitsweisen, Prozesse und Strukturen geschaffen werden können, um diesen Herausforderungen zu begegnen. Mit dem vorliegenden Themenschwerpunkt wird das Ziel verfolgt, sich konzeptionell-theoretisch wie qualitativ-empirisch mit neueren Dynamiken, Einflussfaktoren und Konsequenzen von Innovationen und Reformen auf Strukturen, Arbeitsweisen und Logiken in Staat und Verwaltung zu befassen. Die Autor:innen leisten mit ihren differenzierten Detailanalysen und -ergebnissen zu den Themen Verwaltungsdigitalisierung, Innovationslabore und Agilität einen wichtigen Beitrag zu einer anhaltenden Debatte.
Innovationslabore als Wegbereiter für die Innovation öffentlicher Aufgabenerfüllung?
Authors: Wellmann Stefanie , Hinz Elmar , Schaefer Christina
Published: July 2024

Innovationslabore versprechen, eine besonders zielführende Herangehensweise zur Förderung von Innovationen im Bereich der öffentlichen Aufgabenerfüllung zu sein. Doch trotz zunehmender Verbreitung des Laborphänomens mangelt es international an einer umfangreichen wissenschaftlichen Auseinandersetzung mit Innovationslaboren des öffentlichen Sektors. Insbesondere über die Laboraktivitäten deutscher Verwaltungen existieren nur wenige empirische Erkenntnisse. Ziel dieses Beitrags ist es, auf Grundlage der Aussagen von Experten aus der deutschen Laborpraxis auf Bundes-, Landes- und Kommunalebene, die Bedeutsamkeit der in Innovationslaboren durchgeführten Innovationsprozesse und der daraus hervorgehenden Ergebnisse für das öffentliche Innovationsgeschehen zu prüfen. Die empirische Untersuchung zeigt, dass die ausgewählten Innovationslabore primär Verbesserungen der Innovationsfähigkeit durch kleine, schrittweise Veränderungen anstreben. Zudem werden aus den Untersuchungsergebnissen Faktoren, die sich förderlich auf Innovationsprozesse und die daraus hervorgehenden Ergebnisse auswirken können, abgeleitet. Daraus erwächst die Frage, ob im Lichte dieser Erkenntnisse Veränderungen von Managementpraktiken als stetige Verwaltungsreformbestrebungen interpretiert werden können.

The empirical study applies cluster analyses to records of the commission on criminal justice reform. By analysing discrepancies in the individual voting behaviour of the commission members, the study identifies distinct clusters which coincide with the commission members’ professional background: While the commission members with a scientific background hardly ever form a homogenous group, commission members who practice law e. g. as judges or who are public servants show a more consistent behaviour. This is attributed to the distinct role perceptions within the respective profession. Overall, the commission members represented mostly conservative values, leading to a criminal justice reform with strong reference to previous drafts. With this in mind, the book furthermore analyses rhetorical strategies used within the legal profession to obscure a person’s involvement in the Nazi-Regime.

Теория решения изобретательских задач и все известные её производные Алгоритмы решения изобретательских задач были созданы в стране и во время, где коммерциализации инновационных решений не придавалось особого значения , можно даже сказать , что на определённом этапе создания Теории и Алгоритма решения изобретательских задач вопросы коммерциализации преднамеренно игнорировались в пользу чисто технологических вариантов инновационных решений , абсолютно оторванных от реальной экономики и в большинстве случаев от реальной жизни Особенно важно оценить необходимость начала инновационного процесса и понять , а лучше рассчитать все возможные варианты развития событий в процессе коммерциализации
