Dynamic Recrystallization Behavior

The dynamic recrystallization behavior and texture evolution of surface, quarter and center layers of as-cast Fe-4.53%Si non-oriented electrical steel during hot compression were studied by optical microscope and electron backscatter diffraction. The surface layer of cast ingot exhibited elongated columnar grains with pronounced {001}<130> and {001}<120> textures, while the quarter and center layers of ingot were mainly large equiaxed grains corresponding to strong {100}<0vw> texture. During hot compression, the shear bands were easy to form in the deformed grains with higher stored energy such as {110}<001>, {014}<114> and {312}<332> grains which is conducive to promoting recrystallization. Due to that the shear band was not easy to form in the {100}<0vw> grain with lower stored energy, the large grains corresponding to strong {100}<0vw> texture in the quarter and center layers of ingot undergone obvious deformation and slight orientation transformation during hot compression process which proved the good heritability of as-cast {100} texture.
