Fe-Cu-Nb-V-Si-B纳米晶合金磁导率与温度的关系
, PP. 200-204
Keywords: Fe-Cu-Nb-V-Si-B合金,纳米晶合金,磁导率的温度关系
Abstract:
研究了不同温度（530—620℃）退火后的Fe72．7Cu1Nb2V1．8Si13．5B9纳米晶合金初始磁导率μi与温度T的关系（μi-T曲线）．实验结果表明，退火温度Ta对μi－T曲线的形状有较大的影响．根据Ta可将μi－T曲线划分为三种类型，其对应的退火温度分别为（1）Ta=530—550℃，（2）Ta=560—590℃，（3）Ta600℃．分析了这三种类型的μi－T曲线对应的合金相结构，讨论了双相纳米晶合金中晶体相的晶粒尺寸、体积百分数及剩余非晶相的磁特性对μi-T曲线形状的影响．
