- Abstract:
- The mechanical alloying of FeNiPB(Cu, Nb)mixed powders was studied by X-ray diffraction(XRD), transition electron microscope(TEM), scanning electron microscopy(SEM)and extended X-ray absorption fine structure(EXAFS). The results show that the FeNiPB(Cu, Nb)mixed powders alloy after milling for 20 h, as the milling time increases to 80 h, Fe and Ni atoms are in an amorphous environment, the morphology of FeNiPB(Cu, Nb)mixed powders appears as cotton fiber and its electron diffraction pattern shows a typically diffuse amorphous halo. So FeNiPB(Cu, Nb)mixed powders transform to amorphous state under this condition. After the FeNiPB(Cu, Nb)amorphous alloy was heated at 520 ℃ for 1 h, the nanocrystalline FeNiPB(Cu, Nb)was produced. So, the Fe-based nanocrystalline alloy can be prepared by partially crystallizing the FeNiPB(Cu, Nb)amorphous alloy.
