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%25 and 25%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
