Hydrogen Movement in Steel by Ellis E. Fletcher,Arthur R. Elsea Pdf

This report discusses the ways in which H2 enters steels, how it moves through steel, and methods whereby it may be removed from steel. The solubility of H2 is important in understanding other aspects of the behavior of H2 in steel and such aspects of solubility as preferred lattice sites, lattice expansion, measurements of solubility, and estimates of equilibrium H2 pressure in steel are discussed. The permeation of H2 through steel consisting of interactions at both the entry and exit surfaces of the metal as well as diffusion through the bulk metal is discussed. The various possibilities of H2 entry by corrosion processes, electrochemical processes, and other means are considered as well as factors which influence the rate of H2 removal from iron and steel.

Hydrogen in Steel by Michael Smialowski Pdf

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.

The Problem of Hydrogen in Steel by A. R. Elsea,E. E. Fletcher Pdf

This memorandum introduces the problem of delayed, brittle failures associated with hydrogen in steel, particularly high-strength steel. It is intended to help the steel user determine if he has such a problem. The effects of hydrogen on the mechanical properties of steel are dealt with, and the behavior of material susceptible to delayed, brittle failure is described. Also, the effects of such factors as strength level, magnitude of applied stress, hydrogen content, steel composition, test temperature, and strain rate on hydrogen embrittlement and the susceptibility to hydrogen-induced, delayed, brittle failure are discussed. Possible sources of hydrogen in steel and the types of tests useful in determining the susceptibility to delayed failure are outlined. (Author).

The Effects of High Pressure, High Temperature Hydrogen on Steel by Ellis E. Fletcher,A. R. Elsea Pdf

This report deals with the deleterious effects of hydrogen gas on steel at elevated temperatures and/or pressures. Hydrogen attack on steels is manifest as decarburization, intergranular fissuring, or blistering. These conditions result in lowered tensile strength, ductility, and impact strength. The reaction of hydrogen with iron carbide to form methane is probably the most important chemical reaction involved in the attack on steel by hydrogen. Attack of steel at elevated temperatures and pressures is limited or prevented by the following measures: (1) use of steel alloyed with strong carbide-forming elements, (2) use of liners of resistant alloy steels, and (3) substitution of resistant nonferrous alloys.

Fundamentals of Hydrogen Embrittlement by Michihiko Nagumo Pdf

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.

Hydrogen Diffusion in Metals by D.J. Fisher Pdf

Due to its small size, the hydrogen atom is, wanted or unwanted, an ubiquitous diffusant in many metallic systems. It has long been known for its harmful effect upon mild steel sheet; the deleterious phenomenon of hydrogen-embrittlement having been recognized since the early days of the industrial revolution. Its behavior in some metals is further complicated by its tendency to form hydrides with the metal, or with various non-metallic impurities. The ability of some metals and alloys to store large quantities of hydrogen – first recognized in the 19th century - is another complicating factor. The complexity of metal-hydrogen behavior was undoubtedly also the cause of the mistaken ‘cold fusion’ claims of the late 1980s. The present issue comprises a compilation of hydrogen diffusion and permeation data in metals. These data are believed to be ‘pure’: that is, free from the interfering effects of hydride formation, etc. The almost 600 entries, 201 tables and 41 figures cover the period from 1966 to 2013. These are supplemented by an original review, by T.B.Flanagan of the University of Vermont, which has as its subject, The Role of the Thermodynamic Factor in Hydrogen Diffusion in Metal and Alloy Membranes.

Stress-corrosion Cracking and Hydrogen-stress Cracking of High-strength Steel by Ellis E. Fletcher,Warren E. Berry,A. R. Elsea Pdf

High-strength steels are susceptible to delayed cracking under suitable conditions. Frequently such a brittle failure occurs at a stress that is only a fraction of the nominal yield strength. Considerable controversy exists over whether such failures result from two separate and distinct phenomena or whether there is but one mechanism called by two different names. Stress-corrosion cracking is the process in which a crack propagates, at least partially, by the stress induced corrosion of a susceptible metal at the advancing tip of the stress-corrosion crack. There is considerable evidence that this cracking results from the electrtrochemical corrosion of a metal subjected to tensile stresses, either residual or externally applied. Hydrogen-stress cracking is cracking which occurs as the result of hydrogen in the metal lattice in combination with tensile stresses. Hydrogen-stress cracking cannot occur if hydrogen is prevented from entering the steel, or if hydrogen that has entered during processing or service is removed before permanent damage has occurred. It is generally agreed that corrosion plays no part in the actual fracture mechanism. This report was prepared to point out wherein the two fracture mechanisms under consideration are similar and wherein they differ. From the evidence available today, the present authors have concluded that there are two distinct mechansims of delayed failure. (Author).
