Fabrication of high permeability non-oriented electrical steels by increasing 〈001〉 recrystallization texture using compacted strip casting processes

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

“…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.…”

Effect of hot band grain size on development of textures and magnetic properties in 2.0% Si non-oriented electrical steel sheet

“…11 the values of B 50 () and W 15/50 () are plotted versus () Ah for these seven angles . Clearly, there is a linear decrease of B 50 and a linear increase in W 15/50 with () Ah , which again demonstrates the dependency of magnetic flux density B 50 and core loss W 15/50 on texture [10,12,18,43]. The parameter () Ah in the SG sample varies from 0.17 to 0.22 and that in the LG sample ranges from 0.14 to 0.22.…”

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

“…The significant increase in texture factor of sample S1 annealed at 850 o C for 2 -4 hrs of annealing time (Figure 6a) may be attributed to the oriented growth mechanism (Figure 1). However, the increase in texture factor of sample S2 annealed at 650 o C for 2 hrs of annealing time (Figure 6b) could be attributed to the combination of different recrystallization texture mechanisms 21 . The magnetic property of the samples, represented by core losses, was found to be dependent mainly on the average grain size of the samples although texture factor was also important (Figures 3, 6 and 7).…”

“…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).…”
