摘　　要：采用熔体快淬法制备了Fe52Co26Nb6B15Cu1合金非晶薄带,使用非晶晶化法在480、500、550、600、650℃对其进行等温退火处理,后采用机械球磨法将其球磨得到Fe52Co26Nb6B15Cu1合金微细磁粉。结合X射线衍射分析、振动样品磁强计等测试技术研究热处理温度对Fe52Co26Nb6B15Cu1合金纳米晶的微结构及软磁相关性能的影响。在此基础上使用矢量网络分析仪测试并分析了热处理温度对该纳米晶复合材料在500 MHz^18 GHz磁谱的影响。结果表明,通过控制热处理温度可以有效的调控Fe52Co26Nb6B15Cu1合金样品的微结构与软磁性能,进而在较大范围内调整样品的复数磁导率(μ′(2.0~4.2),μ″(1.0~2.5))。Fe52Co26Nb6B15Cu1 alloy amorphous strip was prepared by the method of melt spin.After being heated at 480 ℃,500 ℃,550 ℃,600 ℃ and 650 ℃,the Fe52Co26Nb6B15Cu1 alloy powder was successfully prepared by mechanical ball milling.After research on soft magnetic characteristic and microstructure which was changed with annealing temperature and tested by XRD,VSM,the micro-magnetic property of composite material was investigated by vector network analyzer in the frequency range of 500 MHz to 18 GHz.The results show that the microstructure and soft magnetic characteristic of Fe52Co26Nb6B15Cu1 alloy sample can be controlled by annealing temperature and due to that,the complex permeability can be controlled in a large scale（μ′（2.0~4.2）,μ″（1.0～2.5））.
