DOWNLOAD EBOOKPerspectives 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.

DOWNLOAD EBOOKHydrogen 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.

DOWNLOAD EBOOKThe understanding of hydrogen/lithium insertion phenomena is of great importance for the development of the next generation of functional electrochemical devices such as rechargeable batteries, electrochromic devices, and fuel cells. This volume introduces a variety of viable electrochemical methods to identify reaction mechanisms and evaluate relevant kinetic properties of insertion electrodes. The authors also outline various ways to analyze anomalous behaviour of hydrogen/lithium transport through insertion electrodes.

DOWNLOAD EBOOKIt 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 EBOOKIt is now more than 100 years since certain detrimental effects on the ductility of iron were first associated with the presence of hydrogen. Not only is hydrogen embrittlement still a major industri al problem, but it is safe to say that in a mechanistic sense we still do not know what hydrogen (but not nitrogen or oxygen, for example) does on an atomic scale to induce this degradation. The same applies to other examples of environmentally-induced fracture: what is it about the ubiquitous chloride ion that induces premature catastrophic fracture (stress corrosion cracking) of ordinarily ductile austenitic stainless steels? Why, moreover, are halide ions troublesome but the nitrate or sulfate anions not deleterious to such stainless steels? Likewise, why are some solid metals embrit tled catastrophically by same liquid metals (liquid metal embrit tlement) - copper and aluminum, for example, are embrittled by liquid mercury. In short, despite all that we may know about the materials science and mechanics of fracture on a macroscopic scale, we know little about the atomistics of fracture in the absence of environmental interactions and even less when embrittlement phe nomena such as those described above are involved. On the other hand, it is interesting to note that physical chemists and surface chemists also have interests in the same kinds of interactions that occur on an atomic scale when metals such as nickel or platinum are used, for example, as catalysts for chemical reactions.

DOWNLOAD EBOOKA mechanistic model has been developed which for the first time considers the effect of hydrogen entry into a metal on the kinetics of the hydrogen evolution reaction (h.e.r.). The model enables computation of: 1) the hydrogen surface coverage and surface concentration; 2) the hydrogen adsorption, absorption, discharge and recombination rate constants; and 3) the h.e.r. coverage-dependent transfer coefficient, alpha and the exchange current density io, from a knowledge of the steady state hydrogen permeation current, cathodic charging current, hydrogen overvoltage and hydrogen diffusivity. The model predicts a linear relationship between permeation flux and square-root of the hydrogen recombination flux and provides an analytical method to determine the cathodic potential range for operation of a coupled discharge-recombination mechanism of the h.e.r. With modifications the model can treat permeation data for which 1) the mechanics of the discharge step involve a (proposed) selvedge reaction; and 2) surface hydrogen coverages are relatively high as in the presence of poisons (e.g., H2S or As2O3). Some of the existing literature data for hydrogen permeation in iron and nickel in acid and alkaline solutions are successfully analyzed. Keywords: Electrochemistry; Hydrogen permeation model; Surface coverage; H.E.R. rate constants; Selvedge reaction; Exchange current; Hydrogen overvoltage; Hydrogen absorption and adsorption rate constants.
