Book Description
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 1 is divided into three parts, the first of which provides an overview of the hydrogen embrittlement problem in specific technologies including petrochemical refining, automotive hydrogen tanks, nuclear waste disposal and power systems, and H2 storage and distribution facilities. Part two then examines modern methods of characterization and analysis of hydrogen damage and part three focuses on the hydrogen degradation of various alloy classesWith its distinguished editors and international team of expert contributors, Volume 1 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 - Reviews how hydrogen embrittlement affects particular sectors such as the petrochemicals, automotive and nuclear industries - Discusses how hydrogen embrittlement can be characterised and its effects on particular alloy classes

Book Description
Research and commercial activity in developing hydrogen as a fuel is driving increased attention on hydrogen-materials interactions. In particular, a renewed and intensifying interest in developing hydrogen fuel cells has prompted extensive research with the objective to enable the safe design of components for transporting and storing hydrogen fuel. This volume is the proceedings from the premier conference on hydrogen effects in materials, bridging scientific research and engineering applications. The proceedings volume highlights several themes: the technological importance of hydrogen effects on structural materials; the impact of bridging science and engineering; and the opportunity to apply new research tools, including simulation techniques as well as experimental methods.

Book Description
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 Description
"Hydrogen embrittlement (HE) is identified as a serious problem even after decades of extensive research, in various industries starting from aerospace to fastener. HE is primarily responsible for the degradation of mechanical performances of a number of metals and alloys that are used nowadays. Among them, high strength steels owing to their widespread applications also suffer from HE failures to a great deal. Hence, this thesis focuses on fundamental issues influencing the susceptibility of three different grades of high strength steels designed for fastener applications.The present work includes investigation of mechanical properties both in presence and absence of hydrogen, microstructural characterisations and direct hydrogen quantification. The mechanical property test methodology is a modification of the ASTM F1624 standard test method to determine hydrogen embrittlement threshold in steels, which facilitates a unique approach to investigate the HE susceptibility of these steel grades. The microstructural characterisation process involves scanning electron microscopy (SEM), electron backscattered diffraction (EBSD) and transmission electron microscopy (TEM) to identify the potential hydrogen trap states in microstructure, both qualitatively and quantitatively. Microstructural characterisation also provides useful information to predict local microstructural evolution in the presence of hydrogen and stress. Altogether, a structure-property relationship has been developed for these materials employing a comprehensive investigation process. In addition to it, fracture surface mapping using SEM indicates the mechanisms of failure associated with HE process in these materials. And finally, direct hydrogen quantification methodology using thermal desorption spectroscopy (TDS) provides further experimental evidence to the above-mentioned facts. Thus, in this work a combined approach involving various research techniques and knowledge has been utilised to investigate the susceptibility of the steel grades and rank them according to their performances under the influence of hydrogen." --

Book Description
The experimental program was undertaken to investigate the possibility of machining fluids being a source of hydrogen for a given high strength aerospace structural alloy. Unexpected catastrophic failure of high strength steel structures can occur as a result of hydrogen embrittlement if the material absorbs high levels of hydrogen during fabrication or when the hardware is in use. Test specimens made of AISI 4340 high strength steel of known hydrogen concentration were subjected to a specified schedule of gentle and abusive milling and grinding operations using different machining fluids. Following the machining operations the specimens were analyzed for excess hydrogen above the base level with a Boeing developed 'Ultrasensitive Hydrogen Analysis System'. A total of six different machining fluids with different active chemical components were used in this study. Experimental results are presented with a statistical analysis of the hydrogen concentration data.
