“…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.…”

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.

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.

“…Paolinelli and Cunha [12] showed that industrial hot band samples of a 1.39% Si, finished in a Steckel mill at 1000°C, resulted in a more favorable final structure and better magnetic properties due to larger grain size after hot band annealing, what is known to favor formation of shear bands in cold rolling. Park and Szpunar [13] studied the effect of initial grain size prior to cold rolling on the texture evolution and magnetic properties in 2% Si non-oriented grain steel and they observed that the magnetic induction of the coarse-grained samples was higher and the core loss was lower at the same temperature than that of the finegrained samples.…”
