The results show that Fe0.13[Co20Ni80]0.87 alloy fibers are characterized with thin diameters between 0.3 and 2.0 μm, with high aspect ratio, dense and smooth surfaces. The crystalline size of the alloy fibers are mainly influenced by the thermal reduction temperature and are in the range of 20 to 50 nm with a corresponding reduction temperature range of 300 to 700 ℃. The magnetic properties of the alloy fibers are largely affected by the carbon content and crystalline sizes of the alloy fibers. With increasing thermal reduction temperature, the coercivity decreases while the saturation magnetisation value of the alloy fibers dramatically increases at lower reduction temperatures. The alloy fibers prepared at reduction temperature of 700 ℃ have a saturation magnetisation value of 120 Am2/kg and a coercivity value of 10.4 kA/m, respectively.

结果表明：Fe0.13[Co20Ni80]0.87合金纤维的直径为0.3~2.0 μm，表面光滑、长径比大；组成合金纤维的晶粒大小与还原温度密切相关，当温度为300~700 ℃时，晶粒尺寸由约20 nm增加到约50 nm；该合金纤维显铁磁性，其矫顽力主要受合金中C含量及晶粒大小的影响，随制备温度的升高而降低；饱和磁化强度则主要与合金的组分相关，随还原温度的升高和合金纯度的提高而增大；经700 ℃热还原后，合金纤维的饱和磁化强度 m s为120 Am2/kg，矫顽力 H c为10.4 kA/m。
