通过玻璃包覆法连续制备出尺寸可控的玻璃包覆的钴基非晶合金微丝.研究了不同退火条件(普通热退火、横向磁场退火和纵向磁场退火)对合金微丝微观结构和磁性能及导电率的影响.采用X射线衍射分析(XRD)、扫描电子显微镜(SEM)测试分析微丝中的相变化,采用振动样品磁强计(VSM)测试微丝的磁性能.发现不同退火条件对非晶基体中析出纳米晶相的成分、尺寸和沿轴向的分布有显著影响,进而对非晶合金丝的磁、电性能产生重大影响.其中,轴向磁场退火可获得最佳的磁性能和电性能,其饱和磁化强度比淬态提高225％,初始磁导率提高214％,导电率提高26％.对比磁退火处理后性能最佳的薄带,该微丝饱和磁化强度提高110％,初始磁导率提高79％,导电率提高45％.
