Study on hydrogen embrittlement susceptibility of pipeline steel under stress

open access: yesYou-qi chuyun
ObjectiveHydrogen embrittlement poses a significant safety risk that restricts the safe operation of hydrogen pipelines. However, there is ongoing debate regarding the extent to which hydrogen penetrates pipeline steel and induces hydrogen embrittlement ...

Effect of cathodic hydrogen charging on the surface of duplex stainless steel [PDF]

open access: yes, 1993
The effect of cathodic hydrogen charging on the mechanical properties of steels has been extensively investigated (1-5). There is a general agreement, that cathodic harging during a tensile test leads to reduction in ductility, and embrittlement (5-7 ...

A three-dimensional multiscale model of intergranular hydrogen-assisted cracking [PDF]

open access: yes, 2010
We present a three-dimensional model of intergranular hydrogen-embrittlement (HE) that accounts for: (i) the degradation of grain-boundary strength that arises from hydrogen coverage; (ii) grain-boundary diffusion of hydrogen; and (iii) a continuum model

Research on Mechanism of Methanol–Hydrogen Co-Transport Inhibiting Hydrogen Embrittlement in Pipeline Steel

open access: yesMetals
Existing studies suggest that hydrogen embrittlement will occur in pipeline steel under a hydrogen environment, and gas is often used as a hydrogen embrittlement inhibitor. As one of the most effective hydrogen carriers, methanol may competitively adsorb

Understanding the interaction between a steel microstructure and hydrogen [PDF]

open access: yes, 2018
The present work provides an overview of the work on the interaction between hydrogen (H) and the steel’s microstructure. Different techniques are used to evaluate the H-induced damage phenomena. The impact of H charging on multiphase high-strength

Embrittlement behaviour of metal additive-manufactured high-entropy alloy components under gaseous and electrochemical hydrogen charging

open access: yesJournal of Materials Research and Technology
Embrittlement is an environmentally induced fracture that primarily affects metallic materials. This phenomenon occurs when hydrogen is absorbed on the metal surface and penetrates to the core, followed by degrading the mechanical properties in a ...
