Journal ArticleDOI
TL;DR: In this paper, the intrinsic complexities of the experimental examination of hydrogen embrittlement are discussed and an experimental approach, in situ electrochemical nanoindentation, is proposed and performed on different materials.

Journal ArticleDOI
TL;DR: In this paper, a review of the synergistic interplay of hydrogen embrittlement mechanisms in STEEL and IR is presented, with a particular emphasis on the proposal of the novel and unified HELP+HEDE model based on the specific microstructural mapping of the dominant HE mechanisms with implications on the fracture process and resulting hydrogen-assisted fracture modes.

Journal ArticleDOI
TL;DR: In this paper, a phase field modeling framework for hydrogen assisted cracking is presented, based on a coupled mechanical and hydrogen diffusion response, driven by chemical potential gradients, and a hydrogen-dependent fracture energy degradation law grounded on first principles calculations.

226 citations

Journal ArticleDOI
TL;DR: In this article, the authors outlined sources of hydrogen attack as well as their induced failure mechanisms in pipeline steels and highlighted several past and recent studies supporting them in line with understanding of the effect of hydrogen on pipeline steel failure.
