In this paper, four types of amorphous spherical powders with different Fe contents were produced by a novel gas-water combined atomization process, and the corresponding magnetic powder cores (MPCs) were fabricated. It was found that as Fe content was increased from 92.66 to 94.55 wt.%, both the D50 and enthalpy of crystallization of the powders decreased and then increased, while the coercivity increased and then decreased together with a linearly enhanced saturation magnetization. Among them, Fe94.55Si1.05B4.3C0.1 amorphous powders have smaller particle size (D50=31.67 μm), excellent sphericity (0.95), good thermal stability (∆T=46 K) and highest saturation magnetization (172 emu·g-1), thus showing the most excellent overall properties. The core loss and the permeability of the corresponding MPCs for the Fe94.55Si1.05B4.3C0.1 amorphous powders is 79.76 kW·m-3 (0.02 T, 100 kHz) and 25.95, respectively, which shows the possibility to develop amorphous powders and MPCs with high Fe content through the present gas-water combined atomization.
