• Hydrogen assisted crack initiation and propagation in a nickel-based superalloy (2016, background): “Since dislocations are able to transport hydrogen during plastic deformation [47,48], these planes with extensive dislocation slip and high dislocation density are believed to contain higher concentration of hydrogen.”

• Hydrogen-assisted failure in Ni-based superalloy 718 studied under in situ hydrogen charging: The role of localized deformation in crack propagation (2017, background): “The contribution of both, the hydrogen transport by dislocations and the occurrence of surface cracks during deformation led to hydrogen distributions that most likely extended farther into the specimen than expected by classical bulk diffusion [36].”
• Enumeration of the hydrogen-enhanced localized plasticity mechanism for hydrogen embrittlement in structural materials (2019, background): “dislocation motion could redistribute hydrogen into very different concentrations profiles than predicted by Fickian diffusion models [64], potenti ally leading to high local concentrations and”
