采用循环加热、冷却过程中测定交流初始磁导率的方法,研究了纳米晶Nix(Fe0.5Co0.5)73.5-xNb3Si13.5B9Cu1(x=5,10,15,20,25,30)合金在由室温升至380730℃范围内的高温磁性与Ni含量的关系。结果表明:与双相纳米晶(Fe0.5Co0.5)73.5Nb3Si13.5B9Cu1合金相比,当Ni含量x≥15时可显著提高FeCo基纳米晶合金的初始磁导率,但同时降低了合金的居里温度。初步探讨了产生这种高温磁性变化的机理。
Temperature dependence of initial permeability was investigated from room temperature to 380～730℃.High-temperature magnetic properties and Ni content for Nix(Fe0.5Co0.5)73.5-xNb3Si13.5B9Cu1(x=5,10,15,20,25,30)alloys were analyzed by means of μi-T curves in heating-cooling cycles.Contrasted with nanocrystalline(Fe0.5Co0.5)73.5Nb3Si13.5B9Cu1 soft magnetic alloy,the initial permeability of FeCo-based nanocrystalline alloys were obviously enhanced when Ni content is x≥15;however,the Curie temperatures of the residual amorphous phase was decreased.The mechanism that the change of high-temperature magnetic properties was also discussed.
