Hydrogen-induced cracking and blistering in steels: A review

May L. Martin et al.

Summary: This paper presents a review of the current state of scientific understanding of Hydrogen-Induced Cracking (HIC), a corrosion phenomenon in low-to medium-strength steels driven by the precipitation of gaseous hydrogen molecules within cracks. HIC is typically observed in sour (H2S containing) environments and involves multiple steps including hydrogen uptake, diffusion, precipitation, and crack growth driven by hydrogen gas pressure. Despite decades of study, a full mechanistic understanding of HIC remains elusive, but the maturation of characterization techniques offers hope for future advancements.

Hydrogen suppression of dislocation cell formation in micro and nano indentation of pure iron single crystals

Peng Gong et al.

Summary: This study investigated the influence of hydrogen on dislocation mobility in pure single crystal iron through experiments and simulations. Hydrogen charging altered the nanoindentation load curve and distribution of dislocations in the material.
