Non oriented electrical steels are soft magnetic materials used in the core of electrical
motors. No preferential anisotropy of the electrical texture in the rolling plane is desired. Nowadays
these special steels are mainly alloyed with Si, Al and some additives to improve the magnetic
properties and to reach a good of formability. For (Si, Al)-concentrations higher than 2 wt.% the α-
γ-α phase transformation is suppressed, resulting in a bcc crystalline structure from liquidus to
room temperature. These electrical steels, which will be discussed in the paper, exhibit the lowest
values of the magnetic losses.
Hot rolling of FeSi electrical steels has been found to be one of the fundamental steps in
producing these materials with optimum properties. The resulting properties, as well known, are
determined by the type of magnetic textures and the structural inhomogeneities. Electron
Backscattered Diffraction (EBSD) is a reliable tool for microstructural and texture characterization
of different materials. Two compositions of electrical steel are studied by optical microscopy and
EBSD, with special attention paid to characterize the grain morphology and its texture through
thickness.
