This paper describes how the magnitude and distribution of residual stresses in cold-rolled 4-6 brass sheets are affected by the reduction and the annealing temperature before rolling. For this purpose the residual stresses in the traverse direction as well as in the rolling direction are measured.The results obtained are summarized as follows :(1) The distributions of the residual stresses in the rolling direction are of the same type ; tension in the surface and compression in the inner layer.(2) The annealing temperature of 600°, 650° and 700°C causes nearly the same residual stresses in the rolling direction.(3) The residual stresses in the traverse direction are changed remarkably by the annealing temperature ; the stress caused by the rolling after annealing at 600°C is much greater than that at 650° and 700°C. And the type of stress distributions is oscillation type, in which compressive and tensile stresses exist alternately.(4) The rate of reduction is almost independent of the residual stresses in both directions.
