Hydrogenated vacancies lock dislocations in aluminium

Due to its high diffusivity, hydrogen is considered a weak inhibitor or even a promoter of dislocation movements in metals and alloys. Here the authors quantitatively demonstrate that after exposing aluminium to hydrogen, mobile dislocations can lose mobility, due to segregation of hydrogenated vaca...
