摘　　要：用扫描电镜和X射线衍射仪观察和分析了熔融快淬法制备的FeCuNbSiB铁基非晶纤维,对影响制备的工艺因素进行了研究,测量了纤维制备态和退火态的电阻率和比饱和磁化强度。结果表明,用快淬法制备的纤维处于非晶态,制备态纤维的电阻率比经300、450、500℃加热1 h退火处理后的高;随退火温度升高,纤维的电阻率和比饱和磁化强度减小,体积分数增大,非晶相减少。纳米晶相的形成明显影响纤维饱和磁化强度的变化。The FeCuNbSiB Fe-based amorphous fibers prepared by melt-quench methed were observed and analyzed by SEM and XRD. The influences of process factors on fabrication technology were studied. The electrical resistivity and specific saturation magnetism of as-prepared and annealed fibers were measured. The results show that the fibers prepared by melt-quench method are amorphous, and as-prepared electrical resistivity is higher than that of annealed at 300,450,500℃ for 1 h. With increasing the annealing temperature,the electrical resistivity and specific saturation magnetism of fibers decrease,the volume fraction of nanocrystalline phase increases and the amorphous one decreases. The nanocrystalline phase influences the variation of fiber＇s saturation magnetism eridently.
