Abstract
Effects of cold rolling conditions on the generation of the surface residual stress in the 5083 aluminum alloy plates were experimentally investigated. The generation behavior of the residual stress was examined in view of plate thickness, working roll diameter and one pass reduction in area. The obtained results were summarized as follows. Thicker specimens exhibited relatively higher surface residual stress in tensile manner than thinner ones. Surface residual stresses decreased with increasing the total reduction in area. The specimen rolled by large working rolls showed higher compressive stress than the specimen rolled by small rolls. The parameters of ωf and (t/l)2 which represent the geometrical conditions in the final rolling process significantly affected the generation behavior of the surface residual stress.
