- Abstract
In this work, the texture evolution, grain boundary character distribution, and magnetic properties of nonoriented Fe–6.9 wt%Si electrical steel are studied. It is found that Fe–6.9 wt%Si steel obtains the higher magnetic inductions based on the heredity of {001} orientation texture during warm rolling, whereas the change in γ‐fiber recrystallization texture is attributed to a significant increase in the frequency of coincidence site lattice grain boundaries after annealing. Meanwhile, the increased recrystallization nuclei in the shear bands lead to the improvement of recrystallization nucleation rate and the decline of grain size because of the accumulation of internal stored energy. Finally, the values of magnetic inductions (B8, B50) and iron losses (P10/50, P10/400) decrease with increasing warm rolling temperatures.
