Available in PDF, EPUB and Kindle. Book excerpt: Premature hydrogen-induced failure observed to occur in many metal systems involves three stages of fracture: (1) crack initiation, (2) stable slow crack growth, and (3) unstable rapid crack growth. The presence of hydrogen at some critical location on the metal surface or within the metal lattice was shown to influence one or both of the first two stages of brittle fracture but has a negligible effect on the unstable rapid crack growth stage. The relative influence of the applied parameters of time, temperature, etc., on the propensity of a metal to exhibit hydrogen induced premature failure was investigated.

This book was released on 2012-01-19 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 1996 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite intense research, a complete mechanistic understanding of the hydrogen embrittlement phenomenon has yet to be achieved. Regardless of the specific mechanism of hydrogen embrittlement, a better understanding of hydrogen transport, hydride formation and their mechanistic effects on stress and strain is needed to elucidate the role of hydrogen in the mechanics of fracture. The thesis consists of five distinct projects, thereby allowing for the analysis of stress induced hydrogen transport in different systems under varying degrees of model complexity. The metal-hydrogen systems are modeled using a continuum mechanics approach and the solutions are obtained via iterative numerical methods. The first project examines the interaction of solute hydrogen atoms with the stress field of a sharp crack in an elastic material under equilibrium conditions. The effect of hydrogen induced volume dilatation and modulus softening on the crack tip stress fields is examined. In the next project, transient hydrogen transport and elastically accommodated hydride formation near a stationary sharp crack in an elastic material are analyzed. The third project considers the competition between hydrostatic stress and plastic strain in determining the interstitial and trapped hydrogen concentrations near a stress concentration in an elastoplastic material. Recent experimental data are considered in the fourth project, in which parameter studies are performed to gain insight into the factors responsible for the development of enhanced hydrogen concentrations in the nickel superalloy, X-750. In the final project, transient hydrogen diffusion and hydride formation near a stationary crack tip in an elastoplastic material are examined. A formulation for determining the effect of an external stress on the terminal solid solubility of hydrogen in an elastoplastic material is presented. A criterion for fracture via hydride formation and subsequent brittle cleavage is proposed and the fracture toughness of a cracked specimen in the presence of hydrogen is shown to be dependent on the tensile loading rate.

Download or read book Hydrogen Transport Microstructure and Hydrogen Induced Cracking in Austenitic Stainless Steels written by C. Altstetter and published by . This book was released on 1988 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Susceptibility to embrittlement in hydrogen gas was investigated for three types of stainless steel alloys having different microstructures. Both slow strain rate notched tension tests and constant load crack propagation tests were used to evaluate susceptibility at 0 to 200°C in hydrogen gas at 108 kPa (1 psig). The alloys were austenitic, ferritic, or austenite/ferrite mixtures produced by different thermomechanical treatments. The onset of embrittlement and crack propagation rates could be correlated with the microstructure of the alloys. Of particular importance to the understanding of the results are the marked hydrogen transport and solubility differences between the austenite and ferrite phases. The stress-induced transformation of austenite to body-centered cubic (bcc) martensite has particular relevance in rationalizing the behavior of various austenitic stainless steel alloys.

Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that about 40% of the annual production of metals is used to repair or replace materials damaged by corrosion. Corrosion causes waste of the natural material and energy resources, it creates serious materials problems for many technologies and adversely affects almost every area of engineering. The use of metals in various aggressive environments has resulted in an extremely wide diversity of corrosion problems. This book presents a collection of concise reviews written by experts in the field on selected topics of metallic corrosion and on some aspects of interaction of hydrogen with metals. A comprehensive range of problems is examined including localized corrosion, high temperature corrosion in liquid metals and molten salts, transport control in corrosion processes, entry of hydrogen into metals, hydrogen embrittlement, and hydrogen reactions with metals. The variety of topics covered in the book will provide corrosion scientists, engineers, university lecturers and students alike with an interdisciplinary approach to solving problems of materials degradation and surface processes in metal corrosion.
Download or read book Hydrogen in Steel written by Michael Smialowski and published by Elsevier. This book was released on 2014-05-09 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen in Steel: Effect of Hydrogen on Iron and Steel During Production, Fabrication, and Use focuses on the effect of hydrogen on iron and steel during production, fabrication, and use. Topics covered range from the solubility of hydrogen in iron and ferrous alloys to the diffusion and permeation of hydrogen through iron and steel. Electrochemical problems related to the ability of iron to absorb hydrogen from aqueous solutions are also considered. Comprised of 19 chapters, this book begins with a detailed treatment of the nature and properties of metal-hydrogen systems, paying particular attention to the behavior of hydrogen in the bulk of the metal phase and the mechanism of reactions between metals and hydrogen or hydrogen-producing compounds. The reader is then introduced to the solubility of hydrogen in iron and ferrous alloys as well as the nature of the final product of the hydrogen-iron interaction. Subsequent chapters deal with dimensional changes and stresses produced in steel by cathodically evolved hydrogen; the effects of hydrogen on the physical, mechanical, and chemical properties of iron and steel; influence of welding on hydrogen; and sulfide corrosion cracking of steel. The effects of pickling on steel are also examined, along with the blistering and embrittlement caused by hydrogen on the base metal during electroplating. This book will be of value to students and practitioners in the field of physical chemistry.
