Disparity in recrystallization of α- & γ-fibers and its impact on Cube texture formation in non-oriented electrical steel

An investigation into the recovery and recrystallization of two major texture fibres, namely α γ, during annealing yielded subtle differences between two. It is reported that with thermal activation static occurs, where dislocation free sub-grains are formed tend to grow, coalesce, or bulge out. This can form new strain-free recrystallisation nuclei, coalescence bulging phenomenon depending on stored energy geometrically density (GND). Due low lattice curvature otherwise, it was found α-fiber has GND values which favours neighbouring deformed grains as opposed subgrain coalescence. In contrast, γ-fiber tends undergo rapid due high curvature, i.e., energy. The newly from both fibers were also typically differ in size, a much higher nucleation rate Furthermore, discovered Cube component though nucleating rates within α-fiber, nucleates all regions densities but will only survive rates, α-fiber. Moreover, Goss preferentially nucleate γ-fiber.
