Effect of Cold Rolling Reduction on Development of Recrystallization Texture of 3 Pct Si Steel Sheet

This study delves into the crucial development of the {111} component in the recrystallization texture of 3 pct Si steel, a fundamental composition of electrical steels. By examining the influence of cold rolling reduction on texture evolution, the research reveals that higher reductions promote a more pronounced and sharper {111} texture, which is essential for achieving superior magnetic properties. The investigation highlights the relationship between subtle misorientation angles and the degree of cold rolling reduction, demonstrating that increased reduction leads to recrystallized grains with orientations closer to the ideal {111} orientation. The study also explores the formation of the Goss texture during secondary recrystallization and its dependency on the primary recrystallization texture. Through detailed analysis of orientation distribution functions and electron backscatter diffraction data, the research provides valuable insights into the mechanisms underlying texture evolution and offers practical implications for optimizing the magnetic properties of electrical steels. The findings suggest that high cold rolling reduction not only produces a concentrated {111} texture in the recrystallization texture but also results in a sharp Goss texture after secondary recrystallization, ultimately enhancing the magnetic performance of the final product.
