Abstract
Abstract The effects of Si and/or P addition in amorphous Fe86+x(B12.5M0.5Cu0.4Hf0.6)14-x (M = P, Si; x = 0.2, 0.4 and 0.6) and Fe86+a(B12N1Cu0.4Hf0.6)14-a (N = PSi; P/Si = 3/1, 1/1 and 1/3; a = 0.2, 0.4 and 0.6) alloys on the amorphous forming ability, thermal stability and soft magnetic properties were investigated. The results indicated that Si had stronger effect on the AFA than that of P element. The increase of Si/P ratio enhanced the AFA. Both Si and/or P addition decreased the onset temperature of the first crystallization, meanwhile the decreased Si/P ratio resulted in higher thermal stability of the second crystallization. After optimal heat treatments, Bs and Hc of the Fe86.4(B12.5Si0.5Cu0.4Hf0.6)13.6 crystallized ribbons reached to 1.95 T and 3.1 A/m, that of the crystallized Fe86.4(B12P0.25Si0.75Cu0.4Hf0.6)13.6 ribbons were 1.98 T and 2.1 A/m, respectively. These materials are potentially applied in the high magnetic flux transaction fields.
