The influence of microstructural features of individual grains on texture formation by strain-induced boundary migration in non-oriented electrical steels

Review of Magnetic Properties and Texture Evolution in Non-Oriented Electrical Steels

“…Cunha et al decreased the stored stain energy of the γfiber texture by two-stage cold-rolling [57]. Further, γ-fiber texture recrystallization is controlled through the temper-rolling process [58,59]. The development of shear bands has a significant influence on the formation of desirable recrystallization textures [60,61].…”

“…De Dafe [58] studied the conventional processing path (thick slab casting, slab reheating, hot-rolling, cold-rolling, and final annealing) for NGO electrical steels (3.0 wt.% Si, 0.004 wt.% C, and 0.55 wt.% Mn). Samples were tested by hot-rolling at different temperatures, cold-rolling by different strains, and finally annealed at 1020 °C.…”

Samples were tested by hot-rolling at different temperatures, cold-rolling by different strains, and finally annealed at 1020 • C. De Dafe [58] finally reported that the best magnetic properties can be achieved by hot-rolling at 1000 • C and cold-rolling with a 64.3% reduction. At the final thickness of 0.5 mm, the tested P 15/60 (core loss at a condition with induction 1.5 T and frequency 60 Hz) was less than 3.0 W/kg.…”

Fabrication of Fe-2.1 wt.% Si Alloy Sheets with Dominant Goss Texture Through Thickness

“…It is known that γ grains mainly nucleate at the grain boundaries of γ deformed grains [5][6][7][8] , and some investigations [2][3][4][5][9][10][11][12][13][14] have revealed some efficient ways to decrease recrystallization γ fiber. Lee et al [2][3][4] reported that increasing the initial grain size can weaken recrystallization γ fiber by reducing the volume of grain boundaries in Fe-2 wt.% Si alloys.…”
