Combined effect of cathodic potential and sulfur species on calcareous deposition, hydrogen permeation, and hydrogen embrittlement of a low carbon bainite steel in artificial seawater
TLDR
In this article, the authors investigated the hydrogen embrittlement of E690 steel in thiosulfate-containing artificial seawater (ASW) under cathodic polarization, and the maximum permeation current was achieved at −850mVSCE due to the change of interfacial pH and promotion ability of sulfur species.About:

On the formation and nature of quasi-cleavage fracture surfaces in hydrogen embrittled steels
TL;DR: In this paper, a combination of topographical reconstruction of secondary electron microscope fractographs and a transmission electron microscopy study of the microstructure from site-specific locations is shown that the features on quasi-cleavage surfaces are ridges that can be correlated with sub-surface intense and highly localized deformation bands.
