Schematic of HELP-assisted decohesion in martensitic steel. Hydrogen is transported to boundaries while the dislocations depositing the hydrogen also deform the boundaries. In martensitic steels, “quasi-cleavage” failures were found to actually be martensitic lath boundary failures, and the boundaries that failed were strongly disturbed by extensive dislocation activity in the form of shear bands.
