The mechanism of secondary recrystallization in electrical anisotropic (grain oriented) steel is considered. The dependence of the degree of perfection of the “sharp” \(\left\{100\right\}\langle 001\rangle \) texture on the effective temperature of the onset of secondary recrystallization is explained by the different influence of the temperature on special boundaries Σ9 and Σ5. The Σ9 boundary preserves its special structure to higher temperatures than the Σ5 boundaries thus ensuring formation of a “sharp” crystallographic texture \(\left\{100\right\}\langle 001\rangle \) due to the high mobility in secondary recrystallization. A hypothesis about the role of the inhibitor phase in the process of secondary recrystallization is formulated.
