| Outline of Final Research Achievements |
In this study, roller burnishing is employed to introduce the shear strain into the surface of the pure iron sheet. And effects of burnishing and annealing on static recrystallization in the finished surface layer are investigated utilizing Electron Back Scattering Diffraction (EBSD) analysis technique. The generation of shear deformation was confirmed by Kernel Average Misorientation (KAM) values at the surface layer. By conducting a series of the annealing and EBSD analyses, the static recrystallization process is observed. Since enough strain energy is accumulated by the burnishing in a specimen with large shear deformation zone, the static recrystallization occurs on the burnished surface preferentially after the annealing.
