In investigation, sheet was alternately bent and then straightened by rolling in 4-step procedure; results showed that greatest increase was in compressive yield stress in width-grain direction regardless of direction of rolling; increase was greater as radius of flexure rolling became smaller and as number of steps was increased; tensile properties were little affected.
