Formation of {001} <510> recrystallization texture and magnetic property in strip casting non-oriented electrical steel

Effects of rolling temperature on microstructure, texture, formability and magnetic properties in strip casting Fe-6.5 wt% Si non-oriented electrical steel

“…It was clearly observed that the in-grain shear bands could act as the dominate nucleation sites for {001}〈210〉, cube, {410}〈001〉 and {115}〈5-10 1〉recrystallized grains, though the grain boundary regions of the deformed λ-grains could also act as the nucleation sites for a few recrystallized grains with abovementioned orientations. It was confirmed that these recrystallized nuclei have an evident advantage in size and number over γ-recrystallized grains through the whole recrystallization stage and finally developed to constitute the dominant recrystallization texture [17,20,30], as shown in Fig. 8a-c.…”

“…5e and f) in the sheets rolled at 750°C and 850°C could evolve into the final coarse annealing microstructure (Fig. 6e and f) through the strain-induced grain boundary migration (SIBM) mechanism [20], resulting in strong α-fiber recrystallization texture besides mild γ-fiber recrystallization texture (Fig. 8e and f).…”

“…On the one hand, it can create extremely fine solidification microstructure owing to its relatively high cooling rate. On the other hand, it can generate desired microstructure and texture in the initial as-cast sheet [9][10][11][12][13][14], which has an influence on the evolution of microstructure and texture during rolling and annealing and the final properties [15][16][17][18][19][20][21][22]. Thus, it may be a new promising low-cost and compact way to produce 6.5 wt% silicon steel sheet by means of strip casting and rolling method.…”

An accurate evaluation of the residual stress of welded electrical steels with magnetic Barkhausen noise

“…Several studies have been published [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] to describe the possibility of applying non-destructive magnetic techniques on the study of changes in microstructure, grain size, stress state and plastic deformation in cold-rolled Non-Oriented Electrical Steels (NOES). Simulations of the performance of magnetic non-destructive techniques in order to investigate the microstructural changes in welded NOES have been carried out in the past [43,44].…”

Effect of Cross-Rolling on Microstructure, Texture and Magnetic Properties of Non-Oriented Electrical Steels

“…This was also observed in the present study which showed that the texture factor was identical in all directions of the samples ( Table 2). The possible explanation for the formation of suitable recrystallization textures can be attributed to a combination of oriented nucleation and oriented growth, deformation accumulated stored energy, geometric softening and orientation pinning 18,20,21 . In the present study, however, the mechanism of recrystallization texture development is not debatable as the texture factor in the samples was not very different ( Figure 6, Table 2).…”
