Abstract
To improve the material characteristics of single and polycrystals of pure aluminum, pure copper, SPCC, SS400, SUS316, and NFG steels, the respective relationships between crystallographic orientations and microstructures, and the bending and mechanical properties were examined. Several grain refinement procedures such as ARB and ECAP methods were performed to obtain an ultrafine-grained structure. Furthermore, some analytical results related to crystal direction maps, inverse pole figures, and textures were obtained from SEM-EBSP analyses. Numerical results from AITAS analyses were also investigated. Results showed that these grained metallic materials have peculiar springback characteristics with various bending angles.
