Abstract

The relative prevalence of {111}<112> and {111}<110> orientations in the recystallization texture of a partially annealed cold rolled Ti-IF steel was examined using Electron Back-Scattering Diffraction (EBSD). A disproportionately high number of recrystallized grains with a near {111}<112> orientation were observed at the grain boundaries between {111}<uvw> and {hkl}<110> deformed grains. It is suggested that the presence of "soft" {hkl}<110> orientations adjacent to a {111}<uvw> grain impacts upon the development of the deformation structure in that grain in such a way as to favour the formation 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 cold rolled IF steels.
