Book Description
On the basis of the information available, steels(ferritic, martensitic, and bainitic), nickel-base alloys, and titanium alloys become embrittled in pure-hydrogen-gas environments at ambient temperature. The embrittling effect is detected by making tension tests on sharp-notched specimens in an environment of high-purity hydrogen gas and, for comparison, tests on similar specimens in an inert gas at the same temperature and pressure. If the material is embrittled by hydrogen, its notch tensile strength will be reduced. The effect is more pronounced as the hydrogen-gas pressure is increased, but in some cases the embrittling effect has been observed at 1 atmosphere of pressure. The effect is more pronounced for the high-strength steels and high-strength nickel and titanium alloys than for the low-strength alloys. In unnotched specimens exposed to a pure-hydrogen environmental, hydrogen embrittlement manifiests itself as a decrease in ductility. Results of tests on stable austenitic stainless steels such as Types 310 and 316, or certain aluminum alloys such as 6061-T6, 2219-T6, and 7075-T73, and beryllium copper indicate that there is no significant evidence of embrittlement of these alloys in hydrogen gas at pressures up to 10,000psi.

Book Description
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.

Book Description
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.
