摘要
研究了不同退火温度下形成的纳米晶Fe_(74.5)Cu_1Nb_2Si_(17.5)B_5合金经过磁场退火后,其饱和磁致伸缩系数λ_S、矫顽力H_C和μi-T曲线的变化。研究表明,经过磁场退火后,纳米晶合金的矫顽力出现不同程度的降低,温度在350℃以下时,初始磁导率表现出明显的提高,这些性能的改善归因于合金饱和磁致伸缩的减小。
The influence of magnetic field annealing on the saturation magnetostriction (λs) and coercive force (H c) together with μi-T curves for Fe74.5 Cu1Nb2Si17.5 B5 nanocrystalline alloy was investigated. It was found that Hc decreased and μi enhanced at relatively lower temperature (below 350 ℃) for field annealed samples, which is due to the reduced λs.
