Soft Magnetic Properties of Ring-Shaped Fe-Co-B-Si-Nb Bulk Metallic Glasses
Takayuki Ishikawa,Takahiro Tsubota,Teruo Bitoh 한국자기학회 2011 Journal of Magnetics Vol.16 No.4
The reduction of the Nb content in the (Fe0.75B0.20Si0.05)96Nb4 bulk metallic glass (BMG) has been studied. The glass-forming ability (GFA) is reduced by decreasing the Nb content, but it can be enhanced by replacing partially Fe by Co. Furthermore, the saturation magnetization of the (Fe<sub>0.8</sub>Co<sub>0.2</sub>)<sub>76</sub>B<sub>18</sub>Si<sub>3</sub>Nb<sub>3</sub> BMG is 1.35 T, being with 13% larger than that of the base alloy (Fe<sub>0.75</sub>B<sub>0.20</sub>Si<sub>0.05</sub>)<sub>96</sub>Nb₄. (Fe<sub>0.8</sub>Co<sub>0.2</sub>)<sub>76</sub>B<sub>18</sub>Si<sub>3</sub>Nb<sub>3</sub> BMG exhibits slightly larger B<sub>800</sub> (the magnetic flux density at 800 A/m) and smaller core losses (20%-30%) compared with the commercial Fe-6.5 mass% Si steel.
