“…In duplex stainless steels, transformation can be provoked by electrochemical hydrogen charging. Sobol et al [10] showed the formation of both ε-and α'martensite through electron backscatter diffraction (EBSD) measurements after electrochemical charging with deuterium. Glowacka et al [11] observed the formation of α'martensite laths in austenite through TEM measurements.…”

“…299 It allows a direct observation of H distribution and provides important basis for studying H diffusion and trapping. 300 To analyze a relatively wide mass range, a time-of-flight (TOF) analyzer is used, and the instrument is thus called TOF-SIMS with a lateral resolution of approximately 150 nm. With the advancement of nanoscale SIMS, the spatial resolution can reach about 50 nm, which enables local microstructural characterization.…”

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.

“…Duplex stainless steels have high resistance to hydrogen induced cracking in sour H 2 S environments. However, the precipitation of M 23 C 6 at the A/È interface [49], which is associated with the carbon and chromium partitioning, may cause a dramatic deterioration in hydrogen induced corrosion resistance in acidic environments [50]. Na2S + 2H + = 2Na + + H2S…”

The corrosion behavior of 2205 DSS in HCl solutions containing sulfide were investigated using mass loss test, electrochemical measurements, scanning Kelvin probe, scanning electron microscope (SEM) and X-ray photoelectron spectroscopy (XPS). The results showed that Na2S had significant effect on corrosion behavior of 2205 DSS in dilute HCl solutions. Slight Na2S can prevent the passive film from localized attacking of Cl- in HCl solution with a concentration lower than 0.1 mol/L. However, when the concentration of HCl solution higher than 0.137 mol/L, Na2S addition will tremendously promote corrosion. The intergranular corrosion combined surficial active dissolution of 2205 DSS could happen in HCl + Na2S solution.
