Magnetic properties of commercially produced Fe-6.5wt% Si sheet

Magnetic properties of high-Bs Fe–Cu–Si–B nanocrystalline soft magnetic alloys

“…The frequency (f) dependence of P for toroidalcore specimen is shown in Fig. 4 together with Fe-6.5 wt% Si-steels and Fe-based amorphous alloy [5,10]. The present alloy shows excellent f dependence of P up to high f.…”

“…4. P vs. f curves at B=0.2 T for toroidal core of Fe 80.5 Cu 1.5 Si 4 B 14 nanocrystalline alloy, Fe-6.5 wt% Si-steel and Fe-based amorphous alloy [5,10]. …”

High Bs nanocrystalline Fe84−x−yCuxNbySi4B12 alloys (x=0.0–1.4, y=0.0–2.5)

“…The B s and H c of the Fe 82 Cu 1 Nb 1 Si 4 B 12 alloy were about 1.78 T and 3.2 A/m, respectively. In Table 1, the B s , H c , and core loss P of Fe 82 Cu 1 Nb 1 Si 4 B 12 nanocrystalline alloy under several conditions are compared with those of the Fe 80.5 Cu 1.5-Si 5 B 13 nanocrystalline alloy [7,9], Si steels [13,17], and Fe-based amorphous alloy [15]. Here, the symbols P 15/50 , P 10/400 , and P 10/1k stand for core losses at 1.5 T at 50 Hz, at 1.0 T at 400 Hz and at 1.0 T at 1 kHz, respectively.…”

“…The B s , H c , and iron loss P of Fe 82 Cu 1 Nb 1 Si 4 B 12 nanocrystalline alloy under several conditions are compared with those of the Fe 80.5 Cu 1.5 Si 5 B 13 nanocrystalline alloy, Si steels, and Fe-based amorphous alloy[7,9,13,15,17].…”

Effect of Annealing Temperature on Soft Magnetic Properties of Cold Rolled 0.30 mm Thick Fe-6.5wt.%Si Foils

“…Several fabrication methods have been developed to avoid the brittleness of this Fe-6.5%Si alloy, such as rapid quenching [4], chemical vapor deposition [5], hot dipping process followed by diffusion annealing [6], magnetron sputtering [7], etc.…”
