Study on primary recrystallization behavior of Fe–3%Si–Cu alloy with copper-rich precipitates as main inhibitor

A Study on the Formation of Fiber Texture in the Subsurface Layer of Hot-Rolled Plate of 3.2%Si Grain-Oriented Steel

“…Inokuti et al [15,16] reported that (110)[001] Goss grains were preferentially formed in specific areas of the hot-rolled plate, and the nuclei of Goss grains in the hot-rolled plate were subsequently preserved through the mechanism of "texture inheritance", resulting in the preferential growth [17] of Goss-oriented grains [18,19] during the secondary recrystallization process [20]. Bottcher [21] and Mishra [22] conducted detailed research on the distribution of α-fiber (<110>//RD), γ-fiber (<111>//ND) and η-fiber (<100>//RD) in the hot-rolled plate of grain-oriented silicon steel, and concluded that, due to the dispersive distribution of inhibitors [23] inhibiting the growth of normal grains [24], abnormal Goss grains grew at the expense of primary recrystallized grains and eventually developed a sharp Goss texture during secondary recrystallization. Bottcher [20] and Inokuti [25] also investigated the effect of the double-surface removal of the hot-rolled plate on grainoriented electrical steel and reported that double-surface removal had a detrimental impact on the secondary recrystallization and magnetic properties of grain-oriented silicon steel.…”
