Effect of the atomic structure of complexions on the active disconnection mode during shear-coupled grain boundary motion
Swetha Pemma, Rebecca Janisch, Gerhard Dehm +1
The migration of grain boundaries leads to grain growth in polycrystals and is one mechanism of grain-boundary-mediated plasticity, especially in nanocrystalline metals. This migra…

Effects of mechanical stress, chemical potential, and coverage on hydrogen solubility during hydrogen-enhanced decohesion of ferritic steel grain boundaries: A first-principles study
Abril Azócar Guzmán, Rebecca Janisch
Hydrogen-enhanced decohesion (HEDE) is one of the many mechanisms of hydrogen embrittlement, a phenomenon that severely impacts structural materials such as iron and iron alloys. G…
