摘　　要：利用AMH-1M-S型动态磁滞特性测试系统测试了铁镓合金的动态磁滞特性。以内径为5.5mm、外径为7.25 mm的环形<100>取向多晶Fe83Ga17合金为测量对象,分别对励磁磁场频率为50、100、200、300、400 k Hz和最大饱和磁密为0.01、0.03、0.05、0.07 T两个方面研究了磁滞曲线和磁特性参数变化规律。实验表明:当励磁磁场频率或最大饱和磁密增加,磁滞曲线变宽、面积增大,剩磁、矫顽力、损耗增加。本文的实验结果为铁镓材料的应用提供了基础参数。The characteristics of Fe-Ga alloy dynamic hysteresis is the foundation of designing the Fe-Ga alloy components.This paper tests the dynamic hysteresis characteristics of Fe-Ga alloyby using AMH-1 M-S type of dynamic hysteresis characteristics testing system. The measuring object is 7.25 mm outer diameter and 5.5 mm inner diameter circular 100 orientation of polycrystalline Fe83 Ga17 alloy.This paper studies the hysteresis curve and magnetic parameters changes both the excitation frequency of the magnetic field of 50 k Hz,100 k Hz,200 k Hz,300 k Hz,400 k Hz,and the maximum saturation flux density of0. 01 T,0.03 T,0.05 T,0.07 T. Experiments show thatwith the magnetic field frequency or maximum saturation flux density increase,the hysteresis curve of width and area is augmented. Simultaneously the remanence,coercive force and loss also increase.The experimental results of this paper provide the basis parameters for the application of the Fe-Ga alloy materials.
