Abstract
Wire-drawn fully pearlitic steel was twisted at room temperature. As a result, a delamination crack propagated along the longitudinal direction of the wire. Backscattered electron and transmission electron microscopy images indicated that the cementite lamellae beneath the delamination crack had vanished. In addition, a fine-grained structure was observed. This indicated that the delamination fracture was not a brittle one but a shear one associated with local severe plastic deformation.
