Hydrogen-induced delayed fracture (HIDF) of 1180 MPa martensitic (MS), dual-phase (DP), and quenched and partitioned (Q&P) advanced high-strength steels was studied using shear-cut U-bend specimens. Fracture maps identified the conditions that caused HIDF. HIDF initiation was largely independent of the bending strain, and was controlled by the sheared edge, creating the critical amount of plastic strain damage required for HIDF. A hydrogen enhanced plasticity (HEP) mechanism caused HIDF. Differing responses to HIDF of the three steels were related to how the microstructures interacted with the stress and strains introduced by shearing. Exploratory work indicated that shear burr arrangement had little influence.
