“…There were only a few Cube grains along the longitudinal direction and surface of the cast strip, and a large number of the new Cube grains nucleated during annealing. Previous studies have indicated that many Cube orientation in shear bands were induced by cold-rolling of grains oriented with {110} [ 16 , 20 ]. Thus, we will discuss the evolution of shear bands during the cold-rolling in some detail.…”

“…{110}<110> (rotated Goss) texture can be directly obtained in Cube orientation shear bands [ 18 , 19 ], but the rotated Goss texture cannot be obtained by hot-rolling, which means that it cannot be used as a conventional method. Interestingly, in our previous work [ 20 ], we found that in Fe-1.3%Si cast strip, the texture obtained by thin strip casting and rolling (TSCR) process had a strong {110} component (including rotating Goss). During cold rolling process, a large number of Cube orientation shear bands were obtained, which significantly increased the strength of Cube texture in the cold-rolled and annealed structure.…”

Evolution of the Shear Band in Cold-Rolling of Strip-Cast Fe-1.3% Si Non-Oriented Silicon Steel

Cube texture and microstructural evolution of as-cast non-oriented silicon steel (1.3% Si) during cold rolling and annealing were studied. The results showed that the as-cast microstructure with grain size in the range of 100–500 μm had a weak texture. The strong orientation was mainly located at {100} and {110} planes. A significant content of shear-deformed grains oriented with {110}<110> were obtained by cold-rolling, and many regions oriented with Cube texture were distributed in the shear bands. During cold-rolling, the orientation of the shear-deformed microstructure tilted towards the {111}<112> orientation, while the matrix orientation retained {110}<110>. On further cold-rolling, the residual part of {110}<110> experienced shear deformation, forming more shear bands, strengthening the Cube orientation. During annealing, Cube orientation grains nucleated in the shear bands leading to strong Cube texture, and corresponding B50 was 1.83T/1.79T.

“…The shear bands formed in grains with these orientations are preferential nucleating sites for Goss and cube grains. Xu et al [32] also found that shear bands formed during the cold rolling of the rotated Goss {110} 110 texture component present in strip-cast non-oriented silicon steel act as favorable nucleation sites during recrystallization annealing. As will be shown below, this type of microstructure has profound effects on the texture and grain size produced during final annealing.…”

The microstructure of a low Si, ultra-low-C, hot-rolled electrical steel strip is modified by annealing at T < To, the α→γ transformation temperature. This heat treatment causes the abnormal anisotropic growth of surface grains which consumes the original hot-rolled microstructure. The growth of the surface grains first takes place parallel to the rolling direction and then in a columnar form parallel to the normal direction until grains growing in opposite directions from the surfaces impinge at the center of the strip. It is shown that cold rolling and a short annealing treatment at temperatures between 700 and 800 °C leads to microstructures which result in iron energy losses that can be as much as 30% lower than those observed in the same material not subjected to the annealing prior to cold rolling. The magnitude of the reduction in energy losses depends on strip thickness and processing parameters. The major effect is observed in material annealed at 710 °C and the relative effect (with respect to material that is not annealed prior to cold rolling) decreases as the strip thickness decreases. It is shown that these effects can be attributed to the effect of the processing conditions on texture and grain size. The maximum reduction in energy losses is observed when the final microstructure consists of ferrite grains ~1.5 times larger than those obtained if the material is not annealed prior to cold rolling.

“…{111} plane textures are the typical recrystallization texture, whose proportion in experimental steels is closely related to the recrystallization degree. {111} plane textures provide nucleation sites for the abnormal growth of Goss grains during secondary recrystallization process [1,12], which are important growth environment for Goss oriented grains [20,21]. In the recrystallization after deformation, the stored energies are different in various texture components, which are {001}⟨110⟩, {112}⟨110⟩, {111}⟨110⟩, and {111}⟨112⟩ in an order from strong to weak.…”

The influence of hot deformation temperature on microstructure and texture of CGO silicon steel under the condition of a high deformation rate (100 s-1) was studied by SEM and EBSD techniques. The results indicate that the typical microstructures at room temperature consist of ferrite and pearlite under different hot deformation temperatures. The higher deformation temperature is beneficial to obtain a more uniform recrystallization microstructure and lower pearlite content. Cubic texture{100}001and rotated cubic texture{100}011are dominant texture components in the tested steels, and{111}112texture inγfiber is also strong, the intensity of which is higher than that of{111}110texture. Goss texture{110}001is weak. With the rising of the hot deformation temperature,{100}011texture decreases firstly and then increases at 1100°C. When the hot deformation temperature raises from 800°C to 900°C,{111}112texture shows an increasing trend, while{111}110texture content is stable. When the temperature further increases to 1100°C and 1150°C,{111}112and{111}110textures are slightly weakened.
