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．
The correlation between initial permeability μi and temperature T (μi-T curve) for nanocrystalline Fe72. 7 Cu 1 Nb2 V 1. 8 Si13. 5 B9 alloy annealed at 5 30 ─ 6 20℃ was investigated.The experimental results showed that the annealing temperature Ta has significant effects on μi-T curve. Three types of μi-T curves were observed. The corresponding annealing temperatures are (1) Ta=530 - 550℃t, (2) Ta=560 - 590℃ and (3) Ta 2600℃. The phase structure of alloy corresponding to the three types of μi-T curves was analysed and the effects of the grain size and volume fraction of α-Fe(Si,V) phase as well as the magnetic properties of residual amorphous phase on μi-T curve were also discussed.
