In this study, how crystallographic texture and changes in microstructure affect the magnetic properties of a semi‐processed non‐oriented (NO) electrical steel, which is investigated its as‐received state after heat treatment, evaluated. Electron backscattered diffraction analysis shows variation with orientation changing from predominance γ α fibers to random one significant increase components <100> directions sheet plane, are desired for NO steels because they parallel direction...
This study focuses on evaluating how the evolution of crystallographic texture and changes in microstructure affect magnetic properties a non oriented electrical steel. For this purpose, semi-processed steel was investigated both its as-received state after heat treatment. Electron Backscatter Diffraction (EBSD) analysis shows that exhibits high fraction grains with orientation close to γ fiber, treatment, exhibited significant reduction no preferential fiber orientation. Additionally,...
