Formation mechanism of recrystallization nuclei in polycrystalline alpha-Fe
Cold-rolling texture of polycrystalline 3%Si-Fe were investigated using high-resolution Electron Backscattered Diffraction (EBSD) method. From the measurement, there are deformation bands with {12 4 1}<014> in a deformed grain. It turned out that the orientation relationship between deformation bands and surrounding deformed grain can be explained by the orientation rotation caused by the activation of the slip system which has a common slip plane with an adjacent grain. {12 4 1}<014> orientation was one of the major components in the recrystallized texture. A hypothesis that recrystallization nuclei is generated directly from the deformation bands formed by an activation of the slip system that has a common slip plane of neighboring deformed grains was proposed from the present experimental results.
