Abstract:Fe78-xMxSi13B9 soft magnetic amorphous alloy powders were prepared by high-energy ball-milling technology.Effects of the addition of transition metal elements M(Zr,Nb and Mo) on microstructure evolution,thermal stability and soft magnetic properties were analyzed by XRD,DSC,SEM and VSM.The results show that the addition of Zr and Nb are helpful to form amorphous phase in Fe-Si-B alloys.The maximum supercooled liquid region ΔTxis 70.62 K.The glass transition temperature Tg and the crystallization temperature Txare respectively 785.05 and 855.67 K.The saturation magnetization Msis 111 emu/g and the coercive force Hc is about 2 028.443 A/m.

Keywords:high-energy ball-milling;soft magnetic amorphous alloy;saturation magnetization
