The (211) [111] single crystals were rolled at room temperature. The effect of shear banding on the deformation behavior of the crystals were metallographically examined. Shear bands are induced in the crystals rolled 50% or more without mechanical twinning. The initial shear bands are of wavy slip bands deviated from the traces of a {111} slip plane. These slip bands are generated closely with each other and developed into the shear bands as the rolling reduction increases. The shear bands are composed of sheet-like regions which are disposed perpendicular to the side surface and inclined about 30 to 35° to the rolling plane of the crystal. The mechanism of shear band formation and the stability of the (211) [111] orientation are discussed.
