Residual stresses in the aluminum sheet specimens rolled from 20 to 89% total sectional reduction were measured. Used reduction per pass was 20% and more heavy percentage. Textures in the sections of these specimens were measured. Normal residual stress generated to the rolling direction is tension in the outer parts and compression in the inner parts of these specimens except heavily reduced ones. In the residual stress distribution of these specimens, the layer where the residual stress changes from tensile to compressed one corresponds to the layer where hardness begins to decrease slightly in the inner part. It has been shown that these residual stresses are correlated with the texture formed by the rolling, and that residual shearing stress in the section has the relation to the structural internal strain caused by the plastic deformation.
