在0≤x≤1.0的成分范围内，研究了Al对纳米晶Fe 73.5 − xAlxCu 1 Nb 3Si 13.5B9合金薄带软磁性能的影响。在1 kHz的相对初始磁导率被发现通过添加Al增加，并在x=0.1时达到峰值。在本工作中研究的整个组合物范围内的Al含量，在x=0和9.3 mOe，在x=1.0的磁化率的值为12.5 mOe的磁化率降低，而显着。然而，在10 Oe的外加磁场下，通过引入Al，磁感应强度适度降低，这可能是由于稀释效应。软磁性能的改善被认为是由于添加Al的合金带的α Fe-Si固溶体相的晶粒尺寸减小，这已经通过透射电子显微镜观察到。另一个因素可能是由于在合金中加入Al时，固有磁晶各向异性K1降低。
The effects of Al on the soft magnetic properties of nanocrystalline Fe73.5−xAlxCu1Nb3Si13.5B9 alloy ribbons are investigated in the composition range of 0≤x≤1.0. The relative initial permeability at 1 kHz is found to increase by the addition of Al, and reaches the peak value at x=0.1. The coercivity decreases, rather significantly, with the Al content in the whole composition range investigated in the present work, the values of the coercivity being 12.5 mOe at x=0 and 9.3 mOe at x=1.0. The magnetic induction at an applied field of 10 Oe, however, decreases moderately by the introduction of Al, possibly due to the dilution effect. The improvement in the soft magnetic properties is considered to result from the reduction in the grain size of the α Fe‐Si solid solution phase of the Al‐added alloy ribbons, which has been observed by transmission electron microscopy. Another factor may be due to the decrease in the intrinsic magnetocrystalline anisotropy K1 as Al is added to the alloy.
