Occurrence of shear bands in rotated Goss ({1 1 0}〈1 1 0〉) orientations of metals with bcc crystal structure

The occurrence of shear bands in the rotated Goss ({1 1 0}〈1 1 0〉) orientation of Fe–1.2 wt.% Si alloy was investigated by the hypothesis of the geometric softening mechanism. The reduction of Taylor factor and the orientation evolution of in-band crystals were calculated by applying the full-constraints Taylor crystal plasticity model. The presence of in-grain shear bands and particularly the Cube-oriented crystal volumes in shear bands was predicted by the models and confirmed by experimental electron backscattered diffraction observation.
