本文研究了高初始磁导率、高频低损耗、高矩形比、低剩磁和恒导磁等5种类型不同性能特点的零磁伸Co基非晶合金在环境温度(-78—100℃)、时效(100℃)以及冲击、振动、碰撞、加速度等条件下直流磁性、磁滞回线、铁芯损耗等变化,并与类似性能的五类晶态Permalloy作了对比,分析了影响不同的可能原因,指出所研究的各类Co基非晶合金作为功率器件和磁导率器件的应用前景。
The effects of the environmental conditions, such as temperature (—78—100℃), 100℃ aging, vibration, collision, shock and acceleration, on the DC and AC magnetic properties of five types of zero-magnetostrictive Co-base amorphous alloys have been stadied. These five alloys are chosen from that of low loss at high frequency, high initial permeability, square loop, high excursion range of induction and constant permeability respectively. All results were compared with five similar crystalline permalloys. The possible causes of various effects on magnetic properties were analyzed. Their suitability for various uses has also been dicussed.
