Advanced Forgings for Highly Efficient Fossil Power Plants
Authors: Blaes N. , Donth B. , Diwo A. , Bokelmann D. 
Published: October 2024

Abstract
In Europe and Japan, great efforts are currently being invested in the development of materials designed to increase the steam temperature in fossil power plants. In the steel segment, the COST program is concentrating on 10% Cr steels with the addition of boron with the aim of achieving a steam temperature of 650°C. With nickel-based materials, the goal is to achieve steam temperatures of 700°C and higher. Alloy 617 has proved to be a very promising candidate in this field and a modified version is currently being developed in Japan. Materials of this type are used in both the turbine and in parts of the boiler.
Creep Behavior of Advanced Power Plant Steels after Long-Term Isothermal Ageing
Authors: Sklenicka V. , Kucharova K. , Svoboda M. , Kroupa A. 
Published: October 2024

Abstract
In this paper we tried to model the creep-strength degradation of selected advanced creep resistant steels which occurs under operating conditions. In order to accelerate some microstructure changes and thus to simulate degradation processes in long-term service, isothermal ageing at 650°C for 10 000 h was applied to P91, P92 and P23 steels in their as- received states. The tensile creep tests were performed at temperature 600°C in argon atmosphere on all steels both in the as-received state and after isothermal ageing, in an effort to obtain a more complete description of the role of microstructure stability in high temperature creep of these steels. Creep tests were followed by microstructure investigations by means of transmission and scanning electron microscopy and by the thermodynamic calculations. The applicability of the creep tests was verified by the theoretical modelling of the phase equilibrium at different temperatures. It is suggested that under restricted oxidation due to argon atmosphere microstructure instability is the main detrimental process in the long-term degradation of the creep rupture strength of these steels.
Life Assessment of High Temperature Welded Components

Published: October 2024

Abstract
The paper describes methods for practical high temperature weldment life assessment, and their application to the analysis of notable high energy piping weldment failures and interpretation of cross-weld data. The methods described in the paper are simplified versions of full continuum damage mechanics (CDM) analysis techniques which have been developed over the last 20 years. The complexity of the CDM methods and their data requirements has been a barrier to their more widespread use. The need for simplified methods has been driven by the need for risk assessment of in-service high temperature welded piping and headers around the world, the need to connect cross-weld data to weld joint design and assessment, and in general, the need to develop suitable guidelines for evaluating the strength of weldments relative to that of base metal.
Creep and Creep-Fatigue Behavior of Grade 92 Base Metal and Welded Joints
Authors: Takahashi Y. , Gandy D. 
Published: October 2024

Abstract
Grade 92 steel, a creep strength-enhanced ferritic (CSEF) steel, is used in supercritical steam fossil power plants for boilers and piping systems. While its creep strength is crucial, understanding the interaction between creep and fatigue damage is also vital for assessing component integrity under cyclic loading. Despite existing studies on its creep-fatigue behavior, additional data under creep-dominant conditions relevant to plant evaluations are needed. Girth welds, critical to piping system integrity, are particularly important in this context. EPRI and CRIEPI initiated a project to develop a comprehensive database on the creep-fatigue behavior of Grade 92 steel's base metal and welded joints and to establish a suitable life estimation procedure. Key findings include: (i) a thick pipe with submerged arc welding (SAW) was manufactured for testing; (ii) base metal and cross-weld specimens showed similar behavior under short-term creep and cyclic loading; (iii) these specimens had lower creep strengths than average literature values for this steel class in the short time regime, with differences decreasing as stress decreased; and (iv) the fatigue and creep-fatigue behavior of these specimens were similar to those of Grade 91 and 122 steels, with common characteristics in creep-fatigue failure prediction models across the three CSEF steels.
The Effect of Duration of Stress Relief Heat Treatments on Microstructural Evolution and Mechanical Properties in Grade 91 and 92 Power Plant Steels
Authors: Li L. , Zhu P. , West G. , Thomson R. C. 
Published: October 2024

Abstract
A detailed examination has been carried out of the microstructural evolution and mechanical properties of samples of T91 and T92 steels which have been subjected to both a ‘normal’ pre­service heat treatment and an extended stress relief heat treatment at 765°C for up to 16 hours. The samples have subsequently been creep tested to failure at different stresses ranging from 66 to 112 MPa. In each case, a reduction in rupture time was observed of 20-30% in the samples which had experienced the additional stress relief heat treatment compared to those which had not. It is shown that these data, when compared with the mean values expected from European Creep Collaborative Committee (ECCC) Datasheets, result in a reduction in stress of approximately 10% of the mean value predicted from the ECCC data, which is within the allowable scatter band.
Processing of Advanced Alloys for A-USC Steam Turbine Applications
Authors: Jablonski Paul D. , Hawk Jeffery A. , Cowen Christopher J. , Maziasz Philip J. 
Published: October 2024

Abstract
As conventional coal-fired power plants seek to reduce greenhouse gas emissions by increasing efficiency, the temperature limitations of traditional ferritic/martensitic steels used in high-temperature components present a significant challenge. With Advanced Ultra Supercritical (A-USC) power plants proposing steam temperatures of 760°C, attention has turned to nickel-based superalloys as potential replacements, since ferritic/martensitic steels cannot withstand such extreme conditions. However, the current absence of cast nickel-based superalloys combining high strength, creep-resistance, and weldability has led to the development of cast analogs of wrought nickel-based superalloys, including H263, H282, and N105. This paper examines the alloy design criteria, processing experiences, as-processed and heat-treated microstructures, and selected mechanical properties of these materials while also discussing their potential for full-scale development.
High-Temperature Mechanical Properties and Microstructure of Cast Ni-Based Superalloys for Steam Turbine Casing Applications
Authors: Maziasz P.J. , Evans N.D. , Jablonski P.D. 
Published: October 2024

Abstract
Advanced UltraSupercritical (A-USC) Steam fossil power plants will operate at steam temperatures up to 760°C, which will require the use of Ni-based superalloys for steam boiler/superheater and turbine systems. In 2008, the Oak Ridge National Laboratory (ORNL) and the National Engineering Technology Laboratory/Albany (NETL/Albany) collaborated to make and test castings of Ni-based superalloys, which were previously only commercially available in wrought form. These cast Ni-based based alloys are envisioned for the steam turbine casing, but they may also be applicable to other large components that connect the steam supply to the steam turbine. ORNL and NETL/Albany have produced small vacuum castings of HR 282, Nimonic 105, Inconel 740, and alloy 263, which are precipitation-hardened Ni-based superalloys, as well as solid-solution superalloys such as alloys 625, 617 and 230. The initial alloy screening included tensile and creep-testing at 800°C to determine which alloys are best suited for the steam turbine casing application at 760°C. HR 282 has the best combination of high-temperature strength and ductility, making it a good candidate for the cast-casing application. Cast and wrought versions of HR 282 have similar creep-rupture strength, based on the limited data available to-date. Detailed comparisons to the other alloys and microstructures are included in this paper.
Strain Induced Hardening of Advanced Austenitic Stainless Steels Evaluation of Creep Properties
Authors: Moody P , Babcock Doosan 
Published: October 2024

Abstract
Cold working and bending during boiler manufacturing can induce strain hardening in austenitic stainless steel, potentially compromising creep ductility and leading to premature failures during operation. While design codes like ASME I, PG 19 provide guidelines for maximum strain levels before solution treating is required, industry concerns suggest these limits may be too high, prompting some boiler manufacturers to implement more conservative thresholds. This study examined the creep ductility of four austenitic stainless steels (TP310HCbN, XA704, TX304HB, and Sanicro 25) at prior strain levels of 12% and 15%, with Sanicro 25 demonstrating the highest ductility, followed by TX304HB, XA704, and TP310HCbN. Solution annealing successfully restored creep ductility to exceed 10% elongation in all materials, though this treatment may be necessary at strains of 12% and 15% for all materials except Sanicro 25 to ensure adequate creep ductility. The findings suggest that ASME I PG 19 guidelines for austenitic stainless steels containing Cb, V, and N should be reviewed, as lower strain limits could help reduce strain-induced precipitation hardening failures.
Mechanical Properties and Microstructures of an S304H-Type Steel Subjected to Hot Working
Authors: Yanushkevich Z. , Mogucheva A. , Tikhonova M. , Belyakov A. , Kaibyshev R. 
Published: October 2024

Abstract
The effect of multiple hot rolling in the temperature interval of 700-1000°C (1290-1830°F) on microstructures and tensile behavior of an S304H-type austenitic stainless steel was studied. The structural changes during hot working are characterized by the elongation of original grains towards the rolling axis and the development of new fine grains. The fraction of fine grains and the average grain size increase with increasing the rolling temperature. The multiple hot rolling results in significant strengthening. The offset yield strength approaches 1080 MPa in the sample processed at 700°C (1290°F), while that of 390 MPa is obtained after rolling at 1000°C (1830°F). On the other hand, the tensile strength at elevated temperatures of 600-700°C (1110-1290°F) decreases with a decrease in the rolling temperature. The relationship between the deformation structures and the tensile behavior is considered in some detail.

Eu, o saber, não falo
Authors: Guarreschi Luciana 
Published: October 2024

Partindo do texto “A coisa freudiana ou o Sentido do retorno a Freud em psicanálise” (Lacan, 1956/1998), mais especificamente da conhecida prosopopeia lacaniana “Eu, a verdade, falo”, a autora produz uma pequena paródia com seu título “Eu, o saber, não falo”, com o objetivo de traçar um caminho o qual toda análise digna desse nome deveria percorrer, que poderia ser enunciado “da busca pelo saber ao furo no saber”. Para tal construção, foi necessário ir a outro texto: “A psicanálise e suas relações com a realidade” (Lacan, 1967/2003a), em que Lacan defende a incomunicabilidade do saber do analista. Como, então, sustentar esse saber, que não fala, sem fazer mistagogia e pender para o obscurantismo religioso sem que o desejo do analista esteja em jogo?

BackgroundDespite its benefits, the Mediterranean diet (MD) is abandoned or not adopted by the younger generations in most Mediterranean countries.ObjectiveThe aim here was to examine some factors determining adherence to MD in Moroccan school-age adolescents.Material and methodsA cross-sectional survey was conducted in a school setting among 386 students (148 boys and 238 girls), aged 14 to 18 years, randomly selected and from different socioeconomic strata. A structured questionnaire was used to collect sociodemographic, socioeconomic and lifestyle data. Physical activity was assessed using the short French version of the IPAQ questionnaire. The KIDMED test was used to assess adherence to the Mediterranean diet.
Weight, height and waist circumference were measured according to WHO standards. Body mass index (BMI) and waist�to-height ratio (WHtR) were calculated. Statistical ANOVA test was used for to compare multiple means, Student’s t-test for independent samples, <i>Chi</i><sup>2</sup> test for categorical variables and multinomial logistic regression analysis to identify factors
associated with adherence to the MD amongst adolescents sample.ResultsAdherence to the MD in this population was very low, with nearly 53% having poor adherence and only 7.7% reporting optimal adherence. Multinomial regression analyses showed that poor adherence is correlated with female gender (p=0.042), low paternal education (p=0.004), limited number of meals (p=0.006), advanced age (p=0.005) and inadequate sleep duration (p=0.027). In contrast, better adherence appears to be correlated with a high number of meals per day (p<0.001) and a better socio-professional class of the father (p<0.001).ConclusionsThis study revealed a low prevalence of good adherence to MD confirming a transition of the study adolescents towards a Westernized diet. Targeted nutritional intervention programs should be implemented to improve adherence to the MD among Moroccan adolescents, by promoting healthy eating habits.
Visualisation of Images and Performance in Music Genres
Authors: Afonina Olena 
Published: October 2024

The purpose of the article is to analyse the visual component in the musical genre (songs) and musical-theatrical genre (ballet), which is an element for the formation of spectacle. The work methodology includes analytical, structural-functional, generalising scientific methods; techniques of comparative analysis to reveal the specifics of modern artistic practices in revealing the specifics of the visual as a component of spectacle. The scientific novelty of the work consists in the analysis of the song “Smerekova Khata”, the musical and stage performance of the “Gerdan” theatre, the ballet “Signs” with the determination of the visualisation of the images laid down by the authors to form the spectacle. Conclusions. Based on the analysis of M. Bakay and P. Dvorskyi's song “Smerekova Khata”, the dependence of visualisation in musical-poetic composition and music, metaphoricity in musical-poetic images in various performing interpretations with a certain amount of spectacularity according to the definition of “spectacularity” in the dictionary of Efron and Brockhaus is determined as a concert, performance. The analysis of the concert performance of the Chernivtsi City Folklore Theatre-Studio “Gherdan” based on the musical and textual material, stage design and costumes of the performers made it possible to reveal the degree of visualisation of musical and stage images that contribute to spectacle in art according to K. Stanislavska's concept as a spectacle with an artistic structure, which is a system of means of expression with external manifestations. The French-American dancer-choreographer Carolyn Carlson's ballet “Signes” (1997, Paris Opera) with scenery by the French artist Olivier Debre and electronic music by the French composer René Aubry fully meets all the parameters of spectacle: a) unusual events that appeal to history with famous heroes Leonardo da Vinci and Gioconda with her outstanding smile; b) entertainment in the presentation of material with the use of three-dimensional pictures that are constantly moving; c) seven different locations; d) lack of verbal text (words), which are compensated by electronic music and choreographic movements.
Michael Tippett: Specification of the Work for Orchestra and Soprano "Byzantia"
Authors: Sokolova Alla 
Published: October 2024

The purpose of the research is to reveal the deep image-sound layers and features of the Irish bardic tradition in the work of M. Tippett through the prism of the work for orchestra and soprano "Byzantium". The methodological basis of the research is historical-conceptual, hermeneutic method and comparative analysis of factual data based on the works of Thomas Weiskel, David Clark, Edward Venn, and Meirion Bowen. Scientific novelty. For the first time in the Ukrainian art history segment, M. Tippett's work for orchestra and soprano "Byzantium" was analysed with an emphasis on the dramaturgy of the composition, cyclical elements, metaphorical sound images, symbolism and characteristic features of the musical and poetic tradition of Irish bards. Conclusions. Biographical collisions of M. Tippett influenced his creative aspirations and attitude to the surrounding world. M. Tippett's aesthetic views are a dialogue between romantic aspirations and sceptical realism of the modern era. Michael Tippett's musical language absorbed both tradition and the entire palette of accumulated world musical experience, as well as duality of meanings, symbolism, imagery and conflict. The work analyses the composition for orchestra and soprano "Byzantium" by M. Tippet, which is based on the mosaic of images, the logical sequence of musical motifs, and cyclicity. It is necessary to highlight the fragmentary nature of musical sections, variable motifs, the presence of contrasting material, the symbolism of magical, changing life force as secular ephemerality, the destruction of the musical text using the technique of expansion and fragmentation. Thus, the composition "Byzantium" is a reincarnation of Irish cultural nationalism in the aspect of traditional forms of bardic poetry. The musical language of M. Tippett in the work "Byzantium" is based on the forms crystallised by the work of L. Beethoven and updated by the musical context of modern and postmodern.
Die Problematisierung und Kontrolle von Jugendkriminalität in Preußen zu Beginn des 19. Jahrhunderts
Authors: Dollinger Bernd 
Published: October 2024

Mit einem Fokus auf Preußen rekonstruiert der Beitrag die Konsolidierung von Jugendkriminalität als institutionelles Problem in der Zeit um 1800. In Anknüpfung an zeitlich vorausgehende Entwicklungen wurde Jugendkriminalität als ein Problem hervorgebracht, das besonderer staatlicher Kontrolle und institutioneller Bearbeitung bedurfte. Diese langfristig folgenreiche Transformation wurde bislang kaum erschlossen. Der Beitrag stellt deshalb Analysen einschlägiger historischer Quellen vor, v. a. der historischen Policey gegen Ende des 18. Jahrhunderts sowie einer umfangreichen Initiative des Preußischen Kultusministeriums im frühen 19. Jahrhundert. Im Ergebnis zeigt sich eine Neu-Orientierung des Fokus und von Maßnahmen sozialer Kontrolle, die zu Beginn des 19. Jahrhunderts darauf abstellten, das familiale und soziale Umfeld von Delinquent*innen auszuleuchten und Kriminalität auf die sozial geprägte, moralische Persönlichkeit junger Menschen zurückzuführen.

Background: Spontaneous intracerebral hemorrhage (SICH) is responsible for higher morbidity and mortality rates than ischemic stroke. Although SICH is less common than ischemic stroke. Identifying the predictors of outcome after spontaneous supratentorial intracerebral hemorrhage is crucial for a clinical decision-making framework and implementing efficient therapeutic measures. Aims: The study aimed to analyze the clinical profile, assess the outcome, and identify the outcome prognosticators after supratentorial SICH in the Neurosurgery Department of a tertiary care hospital in the southeastern part of Bangladesh. Materials and Methods: This prospective interventional study included 183 patients with computerized tomography (CT) evidence of supratentorial SICH above 18 years of age from the Department of Neurosurgery of Chittagong Medical College Hospital between September 2021 and February 2023.The variables analyzed were age, sex, comorbidities, Glasgow coma scale (GCS) score on admission, radiological features, treatment modality and outcome at 90-day. Glasgow outcome scale (GOS) score was used to assess the outcome. GOS score 4-5 was considered good outcome and GOS score 1-3 was considered as poor outcome. Results: The mean age of the patients was 58.9±14.4 years and 52.5% were male. The 90-day mortality rate was 50.8% and 55.2% patients had poor outcomes. On bivariate analysis, higher age, comorbid CKD state, low GCS score, higher hematoma volume, midline shift, hydrocephalus and intraventricular hematoma (IVH) were associated with poor outcome. Independent predictors of poor outcome included a higher baseline age (OR: 1.07, 95% CI:1.02-1.11, p=0.002), lower GCS on admission (OR: 0.55, 95% CI: 0.39- 0.76, p<0.001), and medical management (OR = 30.56, 95% CI = 7.15-130.69, P <0.001). Conclusions: In conclusion, SICH is associated with high mortality and morbidity. Higher age, low GCS on admission and medical management independently predicted poor outcome in the present study. Patients with a lower age, higher GCS on admission and who were managed surgically were more likely to have a good outcome.
