Evolution of recrystallization texture from aluminum sheet cold rolled under unlubricated condition
- Seoul National Univ. (Korea, Republic of)
The texture of cold-rolled aluminum sheet has been known to vary through thickness due to inhomogeneous deformation, which can be caused by a characteristic deformation zone geometry and friction between materials and rolls during rolling. The copper texture is obtained in the center layer, which is plane strain compressed, while the shear texture is in the surface layer, which is approximated by major {l_brace}001{r_brace}{l_angle}110{r_angle} and minor {l_brace}111{r_brace}{l_angle}112{r_angle} and {l_brace}111{r_brace}{l_angle}110{r_angle} components. The recrystallization texture of the surface layer is approximated by {l_brace}225{r_brace}{l_angle}10 5 2{r_angle}. The evolution of the recrystallization texture has been explained by the maximum energy release theory, in which the absolute maximum normal stress direction in the deformed state becomes parallel to the minimum elastic modulus direction of the recrystallized grains.
