Cold rolled Fe-6.5 wt. % Si alloy foils with high magnetic induction

Fe-6.5 wt. % Si alloy foils with 95 mm in width and 0.30 mm in thickness were successfully fabricated by cold rolling process. Excellent magnetic properties (Hc = 20.4 A/m, µm = 22 200, and Bs = 1.69 T) were obtained after annealing at the temperature of 1273 K for 1.5 h. This high magnetic inductio...

Description
Summary:Fe-6.5 wt. % Si alloy foils with 95 mm in width and 0.30 mm in thickness were successfully fabricated by cold rolling process. Excellent magnetic properties (Hc = 20.4 A/m, µm = 22 200, and Bs = 1.69 T) were obtained after annealing at the temperature of 1273 K for 1.5 h. This high magnetic induction is considered to be due to the formation of {hk0}〈001〉 textures. Cut cores from this material have a very low iron loss at frequencies from 400 Hz to 10 kHz.
