Texture and Magnetic Properties of Rolled Fe-6.5 wt.%Si Thin Sheets

Thin (0.20 mm) Fe-6.5 wt.%Si sheets have been successfully fabricated by the continuous rolling method. The designed rolling process parameters, including the initial hot-band grain size, grain size after intermediate annealing, cold rolling reduction, and cold rolling temperature, were selected to control the texture development. Dominant recrystallization eta fiber [rolling direction (RD)//] was achieved after high-temperature annealing. The produced Fe-6.5 wt.%Si thin sheets are promising alternatives for use in power electronics because of their magnetic properties from 400 Hz to 40 kHz.
