摘　　要：Fe基非晶合金材料是目前非晶合金中应用最广泛的体系,它具有优异的软磁性能。通过退火处理消除内应力,是提高软磁性能的关键工艺。本工作研究了以快速升温的方式进行退火处理时,Fe_(80)Si_(9)B_(11)非晶铁芯内外缠绕铜带对其软磁性能的影响。结果表明,采用合理的非晶/铜厚度比、保温温度及时间,利用铜良好的导热性强化传热,使得温度场更均匀、非晶铁芯不同位置矫顽力差异降低,提升了非晶铁芯的初始磁导率,进而提高热处理效率和软磁性能。Fe-based amorphous alloy materials are the most widely used systems in amorphous alloys as magnetic functional materials with excellent performance.Elimination of internal stress through annealing treatment is a key process to improve soft magnetic properties.In this work,the soft magnetic properties of the Fe_(80)Si_(9)B_(11)amorphous ring cores wrapped with copper strips were investigated by a rapid annealing manner.The experimental results indicate that a reasonable amorphous/copper thickness ratio,annealing temperature and time can make the temperature field more uniform due to the good thermal conductivity of copper can enhance heat transfer,which reduces the coercivity difference at different positions of amorphous iron core,improves the initial permeability of amorphous iron core,and then improves the heat treatment efficiency and soft magnetic properties.
