Development of strong Goss texture in ultra-thin high silicon steel with excellent magnetic properties fabricated by two-stage rolling

• A two-stage rolling method successfully produced a 0.2 mm ultra-thin high-silicon steel sheet with a strong Goss texture, achieving superior magnetic properties. • Recrystallized Goss nuclei originate from Goss substructures within shear bands of deformed {111}<112> grains, driven by high stored energy. • Quasi-in situ EBSD revealed that stored energy and grain size critically influence texture evolution, with large deformed grains promoting Goss nucleation and growth. • The resulting annealed sheet exhibits a pronounced Goss texture, leading to enhanced magnetic induction and reduced core loss, beneficial for electric motor applications.
