Many modern energy systems are reliant on the production, transportation, storage, and use of gaseous hydrogen. The safety, durability, performance and economic operation of these systems is challenged by operating-cycle dependent degradation by hydrogen of otherwise high performance materials. This important two-volume work provides a comprehensive and authoritative overview of the latest research into managing hydrogen embrittlement in energy technologies. Volume 2 is divided into three parts, part one looks at the mechanisms of hydrogen interactions with metals including chapters on the adsorption and trap-sensitive diffusion of hydrogen and its impact on deformation and fracture processes. Part two investigates modern methods of modelling hydrogen damage so as to predict material-cracking properties. The book ends with suggested future directions in science and engineering to manage the hydrogen embrittlement of high-performance metals in energy systems. With its distinguished editors and international team of expert contributors, Volume 2 of Gaseous hydrogen embrittlement of materials in energy technologies is an invaluable reference tool for engineers, designers, materials scientists, and solid mechanicians working with safety-critical components fabricated from high performance materials required to operate in severe environments based on hydrogen. Impacted technologies include aerospace, petrochemical refining, gas transmission, power generation and transportation. Summarises the wealth of recent research on understanding and dealing with the safety, durability, performance and economic operation of using gaseous hydrogen at high pressure Chapters review mechanisms of hydrogen embrittlement including absorption, diffusion and trapping of hydrogen in metals Analyses ways of modelling hydrogen-induced damage and assessing service life

This important two-volume book reviews the problem of degradation of metals and other materials exposed to hydrogen. The first part of volume one begins by discussing how the problem of gaseous hydrogen embrittlement affects such sectors as the petrochemicals, automotive, nuclear and other energy industries. Part two reviews ways of characterising and testing for hydrogen-assisted fatigue and fracture. A final group of chapters analyse the ways gaseous hydrogen embrittlement affects high-performance steels, superalloys, titanium and aluminium alloys. The first part of volume two reviews the mechanism of hydrogen embrittlement, including absorption, diffusion and trapping of hydrogen in metals. Part two discusses ways of modelling hydrogen-induced damage and assessing service life. The final section in the book assesses future trends in research. Summarises the wealth of recent research on understanding and dealing with the safety, durability, performance and economic operation of using gaseous hydrogen at high pressure Reviews how hydrogen embrittlement affects particular sectors such as the petrochemicals, automotive and nuclear industries Chapters review mechanisms of hydrogen embrittlement including absorption, diffusion and trapping of hydrogen in metals

Encyclopedia of Interfacial Chemistry: Surface Science and Electrochemistry summarizes current, fundamental knowledge of interfacial chemistry, bringing readers the latest developments. As the chemical and physical properties and processes at solid and liquid interfaces are the scientific basis of so many technologies which enhance our lives and create new opportunities, its important to highlight how these technologies enable the design and optimization of functional materials for heterogeneous and electro-catalysts in food production, pollution control, energy conversion and storage, medical applications requiring biocompatibility, drug delivery, and more. This book provides an interdisciplinary view that lies at the intersection of these three related fields. Presents fundamental knowledge of interfacial chemistry, surface science and electrochemistry and provides cutting-edge research from academics and practitioners across various fields and global regions

Corrosion inhibitors are an important method for minimizing corrosion; however traditional inhibitors such as chromates pose environmental problems. Rare earth metals provide an important, environmentally-friendly alternative. This book provides a comprehensive review of current research and examines how rare earth metals can be used to prevent corrosion and applied to protect metals in such industries as aerospace and construction. Chapter 1 begins by examining the important need to replace chromate, and then goes on to discuss the chemistry of the rare earth metals and their related compounds. Chapter 2 considers the techniques that can be used to identify corrosion inhibition mechanisms and to test the levels of protection offered to different metals by rare earth compounds. Subsequent chapters consider in more detail how rare earth elements can be used as corrosion inhibitors in different forms and for different metals. This includes discussion on the potential of rare earth elements for self-healing, tunable and multifunctional coatings. Finally, chapter 10 considers the cost and availability of the rare earths and the potential health and environmental risks associated with extracting them.

This important, self-contained reference deals with structural life assessment (SLA) and structural health monitoring (SHM) in a combined form. SLA periodically evaluates the state and condition of a structural system and provides recommendations for possible maintenance actions or the end of structural service life. It is a diversified field and relies on the theories of fracture mechanics, fatigue damage process, and reliability theory. For common structures, their life assessment is not only governed by the theory of fracture mechanics and fatigue damage process, but by other factors such as corrosion, grounding, and sudden collision. On the other hand, SHM deals with the detection, prediction, and location of crack development online. Both SLA and SHM are combined in a unified and coherent treatment.

Die Offshore-Windenergie wird in der zukünftigen Stromversorgung eine entscheidende Rolle spielen. Diese Entwicklung steht aber gerade erst an ihrem Anfang. Ein großes Team aus Forschung, Industrie, Verwaltung und Politik hat sich deshalb zum Ziel gesetzt, die aktuellen und grundlegenden Fragen der Offshore-Windenergienutzung zu bearbeiten. Über 100 Forscher der RAVE-Initiative (Research at alpha ventus) arbeiteten in interdisziplinären Forschungsprojekten daran, unser Wissen zu erweitern und anwendungsorientierte Lösungen für die Offshore-Windenergie zu finden. Damit tragen sie dazu bei, die Offshore-Windenergie als eine zuverlässige, nachhaltige und kostengünstige Energiequelle auf Dauer zu etablieren. Im Testfeld alpha ventus, Deutschlands erstem Offshore-Windpark, wurden die Voraussetzungen für diese Forschung geschaffen. Der Windpark wurde mit umfangreicher Messtechnik ausgestattet: Über 1200 Messgrößen werden aufgezeichnet und sind über ein zentrales Forschungsarchiv zugänglich. Die Forscher der RAVE-Initiative haben somit die weltweit einmalige Möglichkeit, eine Vielzahl von Messdaten aus einem operativen Windpark zu nutzen. Die Auswertungen erfolgen dezentral an Forschungseinrichtungen im gesamten Bundesgebiet. Über Ziele, Methoden und Schwierigkeiten der RAVE-Forschungsprojekte wird in allgemeinverständlicher Form berichtet und die Ergebnisse sowie ihre Bedeutung für die weitere Nutzung der Offshore-Windenergie dargestellt. Der Leser erhält somit einen Überblick über den aktuellen Stand der Offshore-Windenergieforschung und die Ergebnisse der Forschungsarbeiten.
