EBSD Investigation on the Primary Recrystallization in Warm Rolled Ti-IF Steel

The nucleus orientations and the nucleation sites at the early stage of recrystallization were studied by EBSD analysis in Ti-IF steel during direct annealing after warm rolling. It is concluded that the formation of the recrystallization texture is dominated by oriented nucleation mechanism. The recrystallized nuclei with γ-orientation emerge preferentially at the beginning of recrystallization and prefer to form inside the γ-oriented deformation bands and on the boundaries between γ and α-oriented bands.
