Formation of {111}< 110 > and {111}< 112 > textures in cold rolled and annealed IF sheet steel

The relative prevalence of {111}[112] and {111}[110] orientations in the re cystallization texture of a partially annealed cold rolled Ti-IF steel was examined using Electron Back-Scattering Diffraction (EBSD). A disproportion ately high number of recrystallized grains with a near (111)(112) orientati on were observed at the grain boundaries between {111[uvw] and {hkl}[110] d eformed grains. It is suggested that the presence of "soft" {hkl} [110] ori entations adjacent to a {111}[uvw] grain impacts upon the development of th e deformation structure in that grain in such a way as to favour the format ion of near {111}[112] nuclei during recrystallization. It is proposed that the formation of in-grain shear bands is an essential part of this process . This mechanism comprises a new explanation for the link between {hkl}[110 ] deformation textures and {111}[112] recrystallization textures seen in co ld rolled IF steels.
