“…This resulting texture affects the final properties of the cold rolled and subsequently recrystallized sheets [8]. Hot rolling conducted mainly in the austenite region leads to a heterogeneous final microstructure with a low magnetic induction whereas rolling in the two-phase region ensures improved magnetic properties [9,10]. Reducing the amount of deformation and decreasing the hot rolling temperature typically induce an enhanced magnetic induction in non-oriented electrical steels [9].…”

“…It was also found that hot band annealing results in enhanced permeability in Fe-Si steels [11,12]. In addition to the TMP parameters, the chemical composition [9,12,13], by way of its influence on phase transformations, plays an important role in both microstructure and texture evolutions. High Si containing grades, i.e.…”

“…Si, Al, Mn, and P) in electrical steels have a considerable effect on the phase transformation behavior, [23] which in turn impacts the hot-rolling microstructure and texture of the steel. In practice, the Fe-(Si + 2Al) phase diagram is commonly used to replace the equilibrium Fe-Si phase diagram to investigate the hot-rolling process of electrical steels.…”

With the objective of optimizing the crystallographic texture of non-oriented electrical steel, i.e., reducing the h111i//ND and h110i//RD fibers and promoting the h001i//ND texture, a new rolling scheme was proposed and tested, in which the cold rolling direction (CRD) was intentionally inclined at an angle to the hot rolling direction (HRD) in order to change the orientation flow paths during cold rolling and alter the final texture of the annealed sheets. A non-oriented electrical steel containing 0.88 wt pct Si was hot rolled using conventional routes and annealed, and a number of rectangular plates were cut from the hot band with the longitudinal directions inclined at various angles, i.e., 0, 15, 30, 45, 60, 75, and 90 deg, to the HRD. These plates were then cold rolled along the longitudinal directions with a thickness reduction of 72 pct. The cold-rolled samples were annealed, temper rolled and annealed again (final annealing). The texture evolution during hot rolling, hot band annealing, cold rolling, and final annealing was characterized by electron backscatter diffraction and X-ray diffraction techniques. By changing the CRD with respect to the HRD, the initial texture and the orientation flow paths were altered, which resulted in apparent differences in the textures as compared to conventional cold rolling. After temper rolling and final annealing, the recrystallization textures consisted of mainly a h001i//ND fiber and there was almost no h111i//ND fiber. The sample cold rolled at an angle of 60 deg to the HRD had the strongest texture (intensity almost 29 of conventional rolling) with a maximum at the cube {001}h100i orientation-a magnetically favorable orientation for non-oriented electrical steels.

“…The impact of silicon content and grain texture was investigated based upon artificial neural networks [9]. Hot rolling conditions were underlined as key elements to the performance of Si-Fe alloys [10]. High permeability and isotropy are required for the steel, while cyclic magnetization should be accomplished with minimum losses.…”
