This paper discusses the anomalous loss behavior in two electrical steels types. Starting from a non oriented electrical steel coil, three groups of samples with different grain sizes were produced. Grain oriented steel samples were produced from a commercially available material. The experimental procedure was performed by means of magnetic properties measurements using an Epstein frame. A procedure to draw the hysteresis curve of the anomalous loss is proposed. The results reported that anomalous loss has a different behavior when the two electrical steel types are compared. In non oriented steels anomalous loss is concentrated at the low induction region. In grain oriented steels, a remarkable participation of high induction region is observed.

“…A graph showing the evolution of the A-parameter as a function of the angle for some ideal texture components and fibres is given in [19]. It was shown there that a perfect theta fibre has an averaged A-parameter of 22.5, which is the same value as for the cube and rotated cube component.…”

The magnetic properties in electrical steels are strongly dependent on the crystallographic texture as well as other microstructural features such as grain size. Both, texture and grain size, are determined by the thermo-mechanical history of the material. This work regards a set of different thermo-mechanical paths applied on two types of non-oriented electrical steels containing 2.4% and 3.0%Si, respectively. The evolution of grain size, microstructure morphology and texture throughout processing were studied in detail by optical microscopy, X-Ray diffraction and Electron BackScatter Diffraction (EBSD). The impact of the texture on the magnetic properties was evaluated. This was done by the calculation of the magnetic anisotropy energy and the A parameter, i.e. a parameter defined in scientific literature that describes the magnetic "quality" of the texture, which can be correlated with the magnetic properties of the materials. Finally, the influence of further laser cutting on the crystallographic texture will be examined as well.

The effect of P, ranging from 0.0 to 0.10 mass%, on the core losses of electrical steels containing 2.0 mass% silicon has been investigated. The core losses were separated into hysteresis losses, classical eddy current losses and anomalous losses. The hysteresis losses were found to decrease with increasing P content due to a larger grain size brought about by P additions. The anomalous losses were proportional to the square root of the grain size, and decreased with increasing volume fraction of grains with a ND || <111> orientation. The lowest anomalous losses were obtained at 0.05 mass% P content.
