Hydrogen Trapping in bcc Iron. [PDF]

open access: yesMaterials (Basel), 2020
Fundamental understanding of H localization in steel is an important step towards theoretical descriptions of hydrogen embrittlement mechanisms at the atomic level. In this paper, we investigate the interaction between atomic H and defects in ferromagnetic body-centered cubic (bcc) iron using density functional theory (DFT) calculations.

Hydrogen trapping and embrittlement in metals – A review

open access: yesInternational Journal of Hydrogen Energy
Hydrogen embrittlement in metals (HE) is a serious challenge for the use of high strength materials in engineering practice and a major barrier to the use of hydrogen for global decarbonization. Here we describe the factors and variables that determine HE susceptibility and provide an overview of the latest understanding of HE mechanisms.

Hydrogen Trapping at Fe/Cu Interfaces. [PDF]

open access: yesMaterials (Basel)
Copper (Cu) in steel production can be a residual element, causing challenges during steel processing, as well as an alloying element, improving corrosion resistance and providing hardenability by nanosized precipitates. For the transition toward a green economy, increased recycling rates in steel production and alternative energy carriers, such as ...

Atomic-scale insights on hydrogen trapping and exclusion at incoherent interfaces of nanoprecipitates in martensitic steels [PDF]

open access: yesNature Communications, 2022
By trapping hydrogen, nanoprecipitates can mitigate the hydrogen embrittlement of high strength steels. Here, the authors report direct evidences on the structural and chemical features underlying distinct hydrogen-trapping behaviors at the incoherent ...

Aromatic Clusters and Hydrogen Storage

open access: yesEnergies, 2023
Concurrence of aromaticity and hydrogen trapping potential of some atomic clusters has drawn the attention of scientific community, although in a few cases it has been reported that the partial charges on the constituent atoms of the clusters are ...

Hydrogen trapping in vanadium carbide alloyed with transition metals

open access: yesNuclear Materials and Energy, 2023
The mechanism of hydrogen trapping in carbides via transition metal alloying is essential for material design of hydrogen barrier coatings in hydrogen energy applications, which however, is still elusive.
