The present work draws upon Diffusion and Defect Forum's 30-year project of summarizing recent progress in the fields of diffusion and defect research, by collating the relevant data which have been published during that time. The large number of studies of iron alloys reflects the great commercial importance of hydrogen embrittlement; an annoying phenomenon which has long plagued steel fabricators.

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

Diffusion in Solids: Recent Developments provides an overview of diffusion in crystalline solids. This book discusses the various aspects of the theory of diffusion. Organized into nine chapters, this volume starts with a discussion on the process of diffusion in solids. This book then examines the tools that supplement the conventional diffusion measurements, including electromigration, ionic conductivity, isotope effects, and vacancy wind effects. This text explores the molecular dynamic calculation by which the interatomic forces must be assumed. Other chapters discuss the method of measurement of the isotope effect on diffusion, which is the most powerful method of determining relevant information about the correlation factor. This volume extensively discusses diffusion in organic and amorphous materials, as well as interstitial diffusion in solids. The final chapter deals with ionic motion and diffusion in various groups of materials called fast ionic conductors. Solid-state physicists, materials scientists, physical chemists, and electrochemists will find this book extremely useful.

Metal hydrides are of inestimable importance for the future of hydrogen energy. This unique monograph presents a clear and comprehensive description of the bulk properties of the metal-hydrogen system. The statistical thermodynamics is treated over a very wide range of pressure, temperature and composition. Another prominent feature of the book is its elucidation of the quantum mechanical behavior of interstitial hydrogen atoms, including their states and motion. The important topic of hydrogen interaction with lattice defects and its materials-science implications are also discussed thoroughly. This second edition has been substantially revised and updated.

Hydrogen can behave as an alkaline metal or a halogen and can react with nearly all elements of the periodic table. This explains the large number of metal hydrides. Since T. Graham's first observation of the absorption of hydrogen in palladium in 1866 the behaviour of hydrogen in metals has been studied very extensively. The interest was motivated by the possible application of metal-hydrogen systems in new technologies (e.g., moderator material in nuclear fission reactors, reversible storage material for thermal energy and large amounts of hydrogen) and by the fact that metal hydrides show very exciting physical properties (e.g., superconductivity, quantum diffusion, order-disorder transitions, phase diagrams, etc.). Many of these properties have been determined for the stable hydrogen isotopes Hand D in various metals. In comparison, very little is known about the behaviour of the ra dioactive isotope tritium in metals. This book is a first attempt to summarize part of the knowledge of tritium gained in the last few years. In addition to the task of presenting the properties of tritium in metals, I have tried to compare these data with those of protium and deuterium. Furthermore, helium-3 is connected inse parably with tritium via the tritium decay. Therefore one chapter of this book is solely devoted to the curious properties of helium in metals caused mainly by its negligible solubility.

Perspectives in Hydrogen in Metals: Collected Papers on the Effect of Hydrogen on the Properties of Metals and Alloys discusses the advancement in the understanding of the effects of hydrogen on the physical and mechanical properties of metals and alloys. The title first covers solubility and other thermodynamic properties, and then proceeds to tackling diffusivity. Next, the selection discusses the trapping of hydrogen by defects and hydride formation. The text also talks about hydrogen in amorphous metals, along with the effect of hydrogen on plastic deformation. The last chapter covers hydrogen embrittlement. The book will be of great use chemists, metallurgists, and materials engineers.
