Texture Evolution of Friction Stir-Processed Dual-Phase Steel
(Springer, 2022) Aktarer, Semih Mahmut; Küçükömeroğlu, Tevfik; Davut, Kemal
Evolution of crystallographic texture and local strains in different zones of a dual-phase steel subjected to severe plastic deformation by friction stir process was examined by electron backscatter diffraction technique. Misorientations, which were expressed by the values of grain orientation spread and kernel average misorientation (KAM), increased from the thermomechanical affected zone (TMAZ) to pin-affected stir zone (PE-SZ). KAM maps showed that the highest local strain appeared in the PE-SZ. Misorientation distributions were found to be consistent with microhardness distributions in the processed region. The crystallographic texture of base metal, heat-affected zone, and TMAZ was similar. Recrystallization and deformation texture components were observed at stir zones, and recrystallization texture components decreased drastically at PE-SZ. Rotated cube, goss and rotated goss texture components were detected at PE-SZ. Rotated cube texture component indicates partial recrystallization after plastic deformation. Shear texture components were determined using shear direction (SD) as reference. Different shear texture components (111), (112), and (101)
