Mechanical and Magnetic Properties Variation in Non-Oriented Electrical Steels with Different Cutting Technology: A Review

“…Crystallographic structure and texture are other important parameters that must be considered when the morphology of the local deformation is analyzed [ 14 , 58 , 59 ]. The main experimental methods to investigate them are electron backscatter diffraction (EBSD), which provides the alloy texture, and optical microscopy, which offers the possibility to visualize the surface microstructure [ 60 ] and to determine through metallographic measurements the average grain size and the grain distribution [ 61 ].…”
