Gaseous Hydrogen Embrittlement of Materials in Energy Technologies
Author: Richard P Gangloff
Publisher: Elsevier
ISBN: 0857093894
Category : Technology & Engineering
Languages : en
Pages : 864
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

Effects of Microstructure Banding on Hydrogen Assisted Fatigue Crack Growth in X65 Pipeline Steels

Pages : 8
Book Description
Banded ferrite-pearlite X65 pipeline steel was tested in high pressure hydrogen gas to evaluate the effects of oriented pearlite on hydrogen assisted fatigue crack growth. Test specimens were oriented in the steel pipe such that cracks propagated either parallel or perpendicular to the banded pearlite. The ferrite-pearlite microstructure exhibited orientation dependent behavior in which fatigue crack growth rates were significantly lower for cracks oriented perpendicular to the banded pearlite compared to cracks oriented parallel to the bands. Thus the reduction of hydrogen assisted fatigue crack growth across the banded pearlite is attributed to a combination of crack-tip branching and impeded hydrogen diffusion across the banded pearlite.

Effect of Absorbed Hydrogen on the Microstructure in the Vicinity of Near-Threshold Fatigue Cracks in Low-Alloy Steel

ISBN:
Category : Environment
Languages : en
Pages : 14
Book Description
The influence of a dry hydrogen environment on near-threshold crack growth propagation rates of fatigue cracks in a low-alloy spheroidized steel was investigated. for separation of environmental and mechanically induced effects, fatigue tests in an ultra-high vacuum (UHV) environment were taken as reference. On a macroscopic scale, we found a significant acceleration of the propagation rates of cracks exposed to a dry hydrogen atmosphere compared to tests in an inert environment. The electron-microscopic characterization of the microstructure in the vicinity of cracks revealed that the acceleration of fatigue propagation by hydrogen can be rationalized by a hydrogen-involved fatigue damage mechanism. Furthermore, it was concluded that hydrogen enhances the dislocation mobility. This effect aids in the formation of dislocation cellular structure in the cyclic plastic zone. The mode of fracture itself is ductile transgranular and appears to be unchanged by absorption of hydrogen at the crack tip.
