amorphous alloys;  Fe base;  Soft magnetic properties

The composition design of multi-component iron-based amorphous Fe-Ni-P-B (TM-M) and Fe-Co-Ni-Zr-Nb-B (TM-(Zr,Nb)-M) systems was analyzed from the aspects of amorphous forming capacity and magnetic properties of the alloy, and the amorphous strips were prepared by the method of rapid quenching of single-roller copper wheel, and X-ray diffraction and transmission electron microscopy (TEM) analysis proved that the samples prepared in this study were uniform amorphous alloys. In addition, it can be seen from the hysteresis loop of the amorphous alloy that the prepared Fe-based amorphous alloy has good magnetic properties.
