Abstract
Commercial purity aluminum (1050) was processed via equal channel angular pressing (ECAP) to one, two, and four passes using route B-c in a 90A degrees channel die, and subsequently compressed in plane strain in two different loading directions, and to two different strain levels. One of the plane-strain-loading directions is parallel to the ECAP forward direction, while the other is perpendicular to it. The flow response in plane-strain compression of the ECAP processed samples revealed an anisotropic behavior, one loading direction systematically gave higher flow stresses. A strain path change parameter was calculated for the two deformation schemes, to justify this anisotropic behavior. Texture evolution, of the plane-strain-compressed samples, was measured, and a transition to the rolling texture was always evidenced. The evolution of the main ideal rolling-texture components obtained from such a combination of deformation schemes, ECAP and plane-strain compression, is presented.
