Influence of dislocation cells on hydrogen embrittlement in wrought and additively manufactured Inconel 718

Communications Materials
Hydrogen embrittlement (HE) is a major issue for the mechanical integrity of high-strength alloys exposed to hydrogen-rich environments, with diffusion and trapping of hydrogen being critical phenomena.

The Role of κ-Carbides as Hydrogen Traps in High-Mn Steels

Metals, 2017
Since the addition of Al to high-Mn steels is known to reduce their sensitivity to hydrogen-induced delayed fracture, we investigate possible trapping effects connected to the presence of Al in the grain interior employing density-functional theory (DFT).

Interfacial engineering of inclusions for synergistic toughening and hydrogen embrittlement resistance in high-strength pipeline steels

npj Materials Degradation
High-strength pipeline steels are susceptible to hydrogen embrittlement (HE), with inclusions exacerbating this vulnerability. This study employed deoxidation to regulate inclusion/matrix interfacial properties, converting them into functional units that
