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 ...

Study on the Influence of Surface Integrity on Hydrogen Permeation Resistance of Hydrogen Production Reactor Materials

open access: yesApplied Sciences, 2023
Hydrogen permeation reduces a material’s properties and increases the risk of brittle fracture, which causes a potential safety hazard. A workpiece’s hydrogen permeation resistance could be improved by improving its surface integrity through surface ...
