Research Abstract

New Fe-metalloids based amorphous alloys with a wide supercooled liquid region of over 50 K have been synthesized by the addition of P and/or C and subsequent optimization of metalloid composition. These alloys can be form a bulk rod specimen with a diameter of up to 3.0mm and exhibit high magnetic flux density of above 1.5T as well as extremely low coercivity. Furthermore the Fe-Si-B-P-Cu bulk amorphous alloy shows both high fracture strength of above 3GPa and high plastic deformability of 4%. On a development of the soft magnetic core, a spark plasma sintered Fe-Si-B-P bulk amorphous core performs lower magnetic core loss than that of typical silicon steel in the high frequency region.
