Book Synopsis The Effects of High Pressure, High Temperature Hydrogen on Steel by : Ellis E. Fletcher
Download or read book The Effects of High Pressure, High Temperature Hydrogen on Steel written by Ellis E. Fletcher and published by . This book was released on 1964 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Fundamentals of Hydrogen Embrittlement by : Michihiko Nagumo
Download or read book Fundamentals of Hydrogen Embrittlement written by Michihiko Nagumo and published by Springer Nature. This book was released on 2023-05-22 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Hydrogen in Steel by : Michael Smialowski
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.

This book was released on 2015 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: Five materials encompassing various grades of carbon steel were received from retired and ex-service petroleum refinery equipment for root-cause evaluation of High Temperature Hydrogen Attack (HTHA) damage at UTK. These materials were submitted by three contributors: Irving Oil Refinery (IOR #1110-2), Valero (#67 & #1252134), and Phillips 66 (#555-S1 & #555-S2) on behalf of American Petroleum Institute (API). These materials originated from various flange-to-pipe welded components that were exposed in hydrogen pressure environment at elevated temperatures (> 640°F and >70 psia). A singular crack originating at the flange inside surface just outside of the visible HAZ was observed in IOR #1110-2 and Valero #67, respectively. Cracking in IOR #1110-2 was 1/4" long in the circumferential direction and ~3/8" deep (3/4 of the flange wall) in the sample received at UTK. A singular crack 5/8" long in the flange circumferential direction and 3/4 deep was found only in one quadrant in the flange base metal just outside of the visible HAZ. However, the cracks in these components (IOR #1110-2 and Valero #67) were different from traditionally accepted HTHA morphology, i.e. no decarburization, no residual methane, and no evidence of cavitation were observed adjacent to crack areas. Cracking in these two components showed a mixture of intergranular and transgranular cracking morphology. No evidence of cracking or microstructural damage was observed in Valero #1252134. The Phillips 66 component, #555-S1 showed the evidence of the beginning stage of HTHA damage with grain boundary microfissures in the flange base metal just outside of the visible heat-affected zone (HAZ); no apparent decarburization was observed adjacent to microfissures. The presence of methane cavities were observed along pearlite/ferrite and ferrite/ferrite boundaries. A residual methane content of 28 ppm was measured in the damaged region of P66 #555-S1 (from the most damaged area). No evidence of fissuring or decarburization was observed in the second component received from P66 #555-S2. The results showed two of the components exhibited nontraditional form of HTHA damage, two components did not exhibit any damage, and one component from Phillips 66 exhibited traditional HTHA damage.

Available in PDF, EPUB and Kindle. Book excerpt: Four carbon steels of approximately equivalent carbon content and varying mainly in the method of steelmaking, i.e., semi-killed, fully-killed, REM-treated, and electroslag refined (ESR), are being studied to determine the effect of deoxidation practice and inclusion morphology on the hydrogen attack of carbon steel. To date tests have been run on a cold-rolled steel (to develop experimental techniques), the semi-killed, and REM-treated materials. Heat treatment for the latter two steels consisted of 60 minutes at 890°C and air cooling to give an average grain size of ASTM No. 8. Significant results are: (1) hydrogen attack results in substantial (factor of ten) greater growth normal to the rolling plane than in the rolling plane; (2) metallography and fractography show a few areas with many microscopic bubbles in the REM-treated steel indicating high bubble nucleation rates on some boundaries and much lower on most boundaries; (3) incubation times, t/sub i/, are on the order of 4 to 5 times that predicted from Weiner's equation. The anisotropy relatives to the rolling plane occurred in all three steels treated. Thus it would seem reasonable that such variables as inclusions or segregation tend to determine the local extent of hydrogen attack. This anisotropy will be examined further in the next series of experiments by comparing all four steels. Of special interest will bethe results of the ESR steel, in which the inclusion content and solidification segregation is significantly reduced.
