“…The subject of work hardening by cutting has indeed attracted substantial efforts in the literature in recent years. These are investigations having a predominant phenomenological character [15][16][17][18][19][20][21][22]. They aim, on the one hand, at determining the extent of the structural damage, the residual stress, and the induction profile across the sample width using, in some cases, neutron grating interferometry.…”

Due to worldwide regulations on electric motor manufacturing, the energy efficiency of these devices has to be constantly improved. A solution may reside in the fact that high quality materials and adequate cutting technologies should be carefully chosen. The magnetic properties of non-oriented electrical steels are affected by the cutting methods, through induced plastic, and thermal stresses. There is also an important correlation between chemical composition and different magnetic properties. In this paper, we analyze different industrial grades of non-oriented electrical steels, used in electrical machines’ core manufacturing as M800-65A, M800-50A, M400-65A, M400-50A, M300-35A, and NO20. The influence of the cutting methods on the normal magnetization curve, total energy loss and its components, and relative magnetic permeability is investigated in alternating currents using a laboratory single sheet tester. The chemical composition and grain size influence are analyzed and correlated with the magnetic properties. Special attention is devoted to the influence of the increased cutting perimeter on the energy losses and to the way it relates to each chemical alloy constituent. The final decision in what concerns the choice of the proper magnetic material and the specific cutting technology for the motor magnetic cores is imposed by the desired efficiency class and the specific industrial applications.

“…On the other hand, the initial grain size is another important factor, and it is much easier to form shear bands after deformation in the sheets with initial coarse grains than fine grains [2][3][4][9][10][11][12][13] . So the relatively large initial grain size above 80 µm through the normalized hot band thickness is very favorable for the formation of shear bands.…”

“…Goss ({110}<001>) is a beneficial recrystallization texture component, because Goss has one easy magnetization <001> direction in the rolling plane, while γ fiber (<111>// ND, normal direction) is detrimental due to the lack of <001> direction in the rolling plane. However, γ recrystallization texture is usually preferentially developed after cold rolling and final annealing in the industrial production [1][2][3][4] .…”

“…It is known that γ grains mainly nucleate at the grain boundaries of γ deformed grains [5][6][7][8] , and some investigations [2][3][4][5][9][10][11][12][13][14] have revealed some efficient ways to decrease recrystallization γ fiber. Lee et al [2][3][4] reported that increasing the initial grain size can weaken recrystallization γ fiber by reducing the volume of grain boundaries in Fe-2 wt.% Si alloys. Paolinelli et al 9 observed that the decrease of α fiber of hot band contributes to weakening recrystallization γ fiber in Fe-3.2 wt.% Si alloy.…”

“…And the texture and microstructure gradient in the hot band can result in the inhomogeneity through the thickness in recrystallization texture due to the inherited effect of texture. Therefore, it is needed to optimize the microstructure and texture characteristics in the whole fabrication process of Fe-2.1 wt.% Si alloy sheets in the industrial production for controlling Goss recrystallization texture through the thickness, which is, however, still far from optimization [1][2][3][4] .…”

Fabrication of Fe-2.1 wt.% Si Alloy Sheets with Dominant Goss Texture Through Thickness

et al. 2019

Macro-and micro-texture of Fe-2.1 wt.% Si alloy sheets were investigated and analyzed by X-ray diffraction and electron backscattered diffraction techniques. A Goss ({110}<001>) component accompanied by extremely weak γ (<111>//ND, normal direction) fiber is successfully formed through the sheet thickness after primary recrystallization and considerable grain growth. Goss grains mainly nucleate at shear bands in various deformed matrices with orientations spreading from <112>//ND to <332>//ND fibers. The formation of dominant Goss recrystallization texture through the thickness can be attributed to the suppression of the nucleation at grain boundaries of γ deformed matrices and the promotion of the nucleation at shear bands in various deformed matrices, based on optimization of the initial texture and microstructure and the applied processing parameters.
