In order to elucidate the mode of deformation introduced by cold rolling of grooved rolls and smooth rolls, plasticinc was used in an experiment on mass flow, and single crystals were employed to test crystal rotation.
When groove-caused protrusions were smoothed on a flatter, a mass flow was observed accompanied by rotation on the axis of groove direction. The transverse mass flow by rotations on the axis of rolling direction was particularly important for the formation of (100) [011] texture. A profound influence on the rotational system of ordinary cold rolling texture would be induced by mass flows as accompanied by rotations. Thus groove rolling is effective in the formation of (100) [011] cold rolling texture. The groove shape, groove arrangement, and groove rolling reduction are largely contributory to the formation of cold rolling texture.
