Grain Size and Texture Evolution During Annealing of Non-oriented Electrical Steel Deformed in Tension

The evolution of grain size and texture during annealing at 700 °C of a low C, Si-Al electrical steel strip is investigated in samples deformed between 3 and 25% in tension. After an incubation period, which decreases as the magnitude of the pre-deformation increases, the grain size-time relationship exhibits two different stages. Initially, the grain growth occurs in some especial grains until they consume the deformed microstructure. In...
