EVOLUTION OF STRAIN STATES AND TEXTURES IN AA 5052 SHEET DURING CROSS-ROLL ROLLING

Abstract

Cross-roll rolling of AA 5052 sheets was carried out using a rolling mill in which the roll axes are tilted by +/- 7.5 degrees away from the transverse direction of the rolled sample. Besides cross-roll rolling, normal-rolling using a conventional rolling mill was also carried out with the same rolling schedule for clarifying the effect of cross-roll rolling. The evolution of strain states during cross-roll rolling was investigated by texture measurements and by three-dimensional finite element method (FEM) simulation. Cross-roll rolling gives rise to the operation of all three shear components epsilon(12), epsilon(13) and epsilon(23) in the roll gap. This complex shear states during cross-roll rolling strongly reduce the intensities of the deformation texture components.
