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

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，Fe65．84-xNi34．16Mox（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（Ma）和居里温度（Tc）单调下降，温度系数△B/△C（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／℃。

The effects of the Mo content in nickel -iron thermomagnetic alloy on the hysteresis loop, Ms-T curve and thermomagnetic property were investigated. The results show that with increasing content of Mo in Fe65.84-xNi34.16Mox （ x = 2,3,4,5 ） alloy, the hysteresis loop becomes flat, Bm （ M, ） and Tc decrease, but △B/△C（0～100℃） decreases after an increase and there＇s a peak of 5.86mT/℃ when the content of Mo is 4at%.
