“…503 It was demonstrated that high angle GBs and grains with tensile axis orientations close to <111>// RD and <112>//RD were more susceptible to H-induced IG cracking. 499,500 The interaction between twins and GBs caused strain localization and promoted microvoid formation. 500 Koyama highlighted that H-assisted cracking can also initiate at deformation twins.…”

Hydrogen is considered a clean and efficient energy carrier crucial for shaping the net-zero future. Large-scale production, transportation, storage, and use of green hydrogen are expected to be undertaken in the coming decades. As the smallest element in the universe, however, hydrogen can adsorb on, diffuse into, and interact with many metallic materials, degrading their mechanical properties. This multifaceted phenomenon is generically categorized as hydrogen embrittlement (HE). HE is one of the most complex material problems that arises as an outcome of the intricate interplay across specific spatial and temporal scales between the mechanical driving force and the material resistance fingerprinted by the microstructures and subsequently weakened by the presence of hydrogen. Based on recent developments in the field as well as our collective understanding, this Review is devoted to treating HE as a whole and providing a constructive and systematic discussion on hydrogen entry, diffusion, trapping, hydrogen–microstructure interaction mechanisms, and consequences of HE in steels, nickel alloys, and aluminum alloys used for energy transport and storage. HE in emerging material systems, such as high entropy alloys and additively manufactured materials, is also discussed. Priority has been particularly given to these less understood aspects. Combining perspectives of materials chemistry, materials science, mechanics, and artificial intelligence, this Review aspires to present a comprehensive and impartial viewpoint on the existing knowledge and conclude with our forecasts of various paths forward meant to fuel the exploration of future research regarding hydrogen-induced material challenges.

“…7b), where a denser deformation twinning was formed. Indeed, by inhibiting twin formation, the hydrogen embrittlement resistance can be largely enhanced [47], since twin-twin and twin-GB intersections show higher strain concentration, and these areas are the critical sites for cracking [40,41,74]. Similar to dislocations, twins lamellae can trigger twin formation on the adjacent grain, appearing as if it is transmitted through the GB and forming adjoining twin pairs under continued straining [75].…”

“…Additionally, a lower strain rate can cause pronounced hydrogen embrittlement by enhancing the twin-slip interactions [31]. Besides the aforementioned factors, the formation of intergranular fracture has been widely reported in TWIP steel under hydrogen attack [39][40][41]. It was demonstrated in a Fe-22Mn-0.6C TWIP steel that low angle grain boundaries (LAGBs) exhibit higher resistance to hydrogen-induced cracking compared to high angle grain boundaries (HAGBs) [41].…”

Beyond that, slow strain rate tests on the same TWIP steel revealed that hydrogen promotes twinning multiplications within grains having tensile axis orientations close to ⟨111⟩ and ⟨112⟩// rolling directions [40].…”

In this study, the effect of hydrogen on dislocation and twinning behavior along various grain boundaries in a high-manganese twinning-induced plasticity steel was investigated using an in situ micropillar compression test. The compressive stress in both elastic and plastic regimes was increased with the presence of hydrogen. Further investigation by transmission electron backscatter diffraction and scanning transmission electron microscope demonstrated that hydrogen promoted both dislocation multiplication and twin formation, which resulted in higher stress concentration at twin–twin and twin–grain boundary intersections.

“…Hydrogen had a large influence on the mechanical properties as illustrated by the dotted lines in Figure 7 As the elongation was calculated based on the crosshead displacement, the EI inherently contains an error and the values do not represent a true quantitative loss in ductility. This procedure is, however, frequently used for in-situ tested austenitic steels [18,65]. Figure 8 shows the EI as a function of the engineering strain rate for the as-received and pre-strained 304L ASS.…”
