Abstract
The rolling deformation has widely been considered equivalent to plane strain compression. The validity of this presumption, particularly at high strains, was tested by comparing the deformation and recrystallization textures in rolled and channel-die compressed copper using the ODF techniques. Noticeable differences were observed in both the deformation and recrystallization (cube) textures of the strips produced by these two deformation methods. For the deformation texture, the rolled strip shows stronger “copper” and “S”, but weaker “brass” components, in comparison with the channel-die compressed strip. For the recrystallized specimens, the cube texture is stronger in the rolled than in the channel-die compressed specimens, and their microstructures are also noticeably different. These observed differences are all more prominent at higher reductions. The causes of these differences will be discussed.
