Effects of processing conditions on the final microstructure and magnetic properties in non-oriented electrical steels

This paper reports the effects of tensile deformation and annealing conditions on the microstructure and magnetic properties of non-oriented electrical steel. The samples were subjected to tensile strains between 8% and 25% and subsequently annealed in air at temperatures from 700 to 900 °C. The experimental results show that the crystallographic texture of annealed samples depends strongly on the annealing temperature. Fibers textures of type 〈011〉//RD, 〈001〉//ND and 〈111〉//ND, are obtained at temperatures below the Ae1. In contrast, annealing at temperatures within the two-phase field region (Ae1
