“…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.…”

“…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.…”

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

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.

Abstract -This article presents an up-to-date magnetic material investigation and overview on magnetic materials used in rotating electrical machines. The focus is on small to medium-sized high-performance and high-efficiency permanent-magnet and induction motors for different application scenarios. The investigated materials include fully processed silicon-iron, nickeliron, and cobalt-iron lamination steels, as well as soft magnetic composites and amorphous magnetic materials. The technical focus of the article is on the magnetic properties and iron losses as well as the manufacturing influence and required thermal treatments during the manufacturing process. A new loss to flux density factor is introduced to compare the characteristic B H magnetization curve and the iron losses of different materials within the same diagram. The aim of the article is to give the machine designer an efficient material overview and selection guide during the early machine design process.

During electrical steel processing, there are usually small variations in both chemical composition and thickness in the hot-rolled material that may lead to different magnetic properties for the same steel grade. Therefore, it is of great importance to know the effects of such variations on the final microstructure and magnetic properties of these steels. In the present investigation, samples of a specific grade of a commercial hot-rolled grain non-oriented (GNO) electrical steel were taken from different steel batches to investigate the effects of thickness and chemical composition (C, Sn, Mn and Ti) in the hot-rolled material on the final microstructure and magnetic properties (core losses and magnetic permeability) resulting from two different decarburizing annealing cycles. Hot-rolled samples were processed by cold rolling, intermediate annealing, temper-rolling and final decarburization annealing using the same processing parameters. The experimental results show that the minimum core losses and maximum magnetic permeability are obtained with the thinnest steel thickness and the largest grain size. Increasing Sb and Mn contents, and reducing the C and Ti concentrations also improve the magnetic behavior of these steels. It was also found the effect of grain size on the magnetic behavior is more significant than the one of crystallographic texture.
