Fundamentals Of Hydrogen Embrittlement

This book is the second edition of the one originally published in 2016, as the first comprehensive treatment on the fundamentals of hydrogen embrittlement of metallic materials, mainly steel. The book provides students and researchers engaging in hydrogen problems with a unified view of the subject. Establishing reliable principles for materials design against hydrogen embrittlement and assessing their performance are recent urgent industrial needs in developing high-strength steel for hydrogen energy equipment and weight-reducing vehicles. The interdisciplinary nature of the subject, covering metal physics, materials science, and mechanics of fracture, has disturbed a profound understanding of the problem. In this book, previous studies are critically reviewed, and supplemental descriptions of fundamental ideas are presented when necessary. Emphasis is placed on experimental facts, with particular attention to their implication rather than phenomenological appearance. The adopted experimental conditions are also noted since the operating mechanism of hydrogen might differ by material and environment. For theories, employed assumptions and premises are noted to examine their versatility. Progress in the past decade in experimental and theoretical tools is remarkable and has nearly unveiled characteristic features of hydrogen embrittlement. Proposed models have almost covered feasible aspects of the function of hydrogen. This second edition has enriched the contents with recent crucial findings. Chapters on the manifestation of embrittlement in the deterioration of mechanical properties and microscopic features are reorganized, and the description is revised for the convenience of readers’ systematic understanding. A new chapter is created for delayed fracture in atmospheric environments as a conclusive subject of critical ideas presented in this book.

The fully updated Fifth Edition of John H. Bickford's classic work, updated by Michael Oliver, provides a practical, detailed guide for the design threaded bolted joints, the tightening of threaded joints, and the latest design procedures for long-term life. New sections on materials, threads, and their strength have been added, and coverage of FEA for design analysis is now included. Referencing the latest standards, this new edition combines fastener materials, explanation of how fasteners are made, and how fasteners fit together, supplementing the basic design coverage included in previous versions of this authoritative text. Introduction to the Design and Behavior of Bolted Joints: Non-Gasketed Joints will be of interest to engineers involved in the design and testing of bolted joints.

Authors of fifteen papers analyse current problems and present their theories and the results of research projects. Contents include: Hydrogen Degradation Phenomena Theories of Hydrogen-Induced Cracking of Steels Hydrogen Trapping in Iron and Steels Fracture Mechanics and Surface Chemistry Investigations of Environment-Assisted Crack Growth Role of Microstructure in Hydrogen Embrittlement Propagation of Stress Corrosion Cracks and Relevance to Proposed Mechanisms of Stress Corrosion Cracking Stress Corrosion Cracking of Ferritic and Austenitic Stainless Steels Fundamentals of Corrosion Fatigue Behavior of Metals and Alloys Hydrogen Permeation and Embrittlement Studies on Metallic Glasses Industrial Occurrence of Stress Corrosion Cracking and Means for Prediction.

The book presents a collection of chapters on the current problems associated with hydrogen damage. It discusses the effect of hydrogen on material properties and its interaction with the material microstructure, physical features of hydrogen transport in metals and alloys, as well as applicable methods of measuring concentration of hydrogen in solid media.

Steels: Microstructure and Properties is an essential text and reference, providing indispensable foundational content for researchers, metallurgists, and engineers in industry and academia. The book provides inspiring content for undergraduates, yet has a depth that makes it useful to researchers. Steels represent the most used metallic materials, possessing a wide range of structures and properties. By examining the properties of steels in conjunction with structure, the book provides a valuable description of the development and behavior of these materials- the very foundation of their widespread use. The new edition has been thoroughly updated with 2 new chapters, expanded content throughout, and numerical Q+As at the end of each chapter, yet it retains its clear writing style, extensive bibliographies, and real-life examples. Revised edition features a new chapter on selection of steels, a new chapter on sustainable use of steels, expanded coverage of surface treatment of steels, crystallographic textures, metallurgical aspects of additive manufacturing of steels, and much more Includes derivations with important equations so that students from a broad range of subjects can appreciate the issues without being bogged down in mathematics Presents micrographs and figures that reflect the resolution and capabilities of modern instruments

This book highlights the latest advances, innovations, and applications in cement-based materials (CBM) and concrete structures, as presented by leading international researchers and engineers at the International RILEM Conference on synergizing expertise toward sustainability and robustness of CBM and concrete structures (SynerCrete), held in Milos Island, Greece, on June 14-16, 2023. The aim of the conference was to discuss and arouse progress in research, development, and application of CBM and structural concrete through combination of expertise from distinct fields of knowledge, such as performance-based design, 3D modeling for analysis/design, building information modeling, and even robotics, while keeping focus on multiscale approaches at time and spatial levels. It covers a diverse range of topics concerning alternative concrete formulations for adaptation to climate change, performance-based and multiphysics/multiscale design and innovative testing, structural health monitoring and maintenance management, integral BIM-based planning, and resource-responsible building. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster new multidisciplinary collaborations. The two volumes encompass more than 200 original contributions in the field.
