Abstract
The effect of hydrogen on the crack tip cyclic slip deformation is investigated using a single-crystalline Fe-3.2%Si alloy. The fracture surface and the near-tip cross-section are observed in detail by SEM and TEM respectively. The cyclic slip-off process by a pair of symmetrical slip system about the crack ((11̄2̄)[11̄1̄] / (11̄2)[1̄11] pair) is operative in the non-hydrogen atmosphere. On the other hand, other pairs of slip system ((011)[11̄1] / (101)[1̄11] pair and (1̄01)[11̄1] / (01̄1)[1̄11] pair) are also found to be operative and slip is localized around the vicinity of the crack in the hydrogen atmosphere.
