Mo元素对铁镍热磁合金性能的影响

Effects of the Mo content in iron-nickel thermomagnetic alloy on the magnetic properties

摘要: 为了进一步提高铁镍热磁合金的性能,系统研究了Mo元素对铁镍热磁材料的磁滞回线、Ms-T曲线和热磁性能的影响规律。结果表明:随Mo含量的增加,Fe_65.84-xNi_34.16Mo_x(x=2,3,4,5)合金的磁滞回线逐渐变得扁平,饱和磁感应强度值(Bm)、饱和磁化强度值(Ms)和居里温度(Tc)单调下降,温度系数△B/△T(0～100℃)值呈先升高后降低的趋势,并在Mo含量为4at%附近出现最高值5.86mT/℃。

Abstract: The effects of the Mo content in nickel-iron thermomagnetic alloy on the hysteresis loop,M_s-T curve and thermomagnetic property were investigated.The results show that with increasing content of Mo in Fe_65.84-xNi_34.16Mo_x（x=2,3,4,5） alloy,the hysteresis loop becomes flat,B_m（M_s） and T_c decrease,but △B/△T（0-100℃） decreases after an increase and there's a peak of 5.86mT/℃ when the content of Mo is 4at%.
