摘要：
Fe78Co2Zr8Nb2B10-xGex (x = 0, 1, 2, 3) amorphous alloys were prepared by melt-spinning and annealed at different temperatures. The microstructures and magnetic property were investigated by X-ray diffraction (XRD), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM), respectively. The crystallization processes of Fe78Co2Zr8Nb2B10 amorphous alloy at different quenching rates are similar and complex. The alpha-Fe(Co) and alpha-Mn type phases are observed in their initial stage of crystallization process. H-c increases with increasing annealing temperature in general. Only alpha-Fe(Co) phase is observed in the initial stage of the crystallization processes of Fe78Co2Zr8Nb2B10-xGex (x = 0, 1, 2, 3) alloys. The change trend of coercivity is complex compared with Ge-free samples. The magnetic property of Fe78Co2Zr8Nb2B7Ge3 is better.
