Evolution of Microstructure and Texture Orientation of A New Non-oriented Electrical Steel during Annealing

Evolution of microstructure and texture oriented of a new non-oriented electrical steel during annealing at 950 ℃ for different times(3-180) s and air cooling was studied by metallography and electron back-scattering diffraction analysis.The results show that after annealing for 3 s most of the texture oriented along α-fibre and γ-fibre,the intensity of {100}〈110〉 was the strongest.{111}〈112〉,{111}〈110〉,{112}〈110〉,Gauss texture and cube texture were the main texture after annealing for 20 s,with the prolongation of annealing time the intensity of Gauss texture and cube texture decreased.The controlling of annealing time could contribute to the increase of {100} and {110} plane texture.
