摘要
研究了频率、磁场及退火工艺对Fe73.5Cu1Nb3Si13.5B9非晶薄带的磁感应效应及磁感应效应变化幅度的影响。结果表明:非晶薄带的磁感应效应随着频率的升高而增强,随磁场的增强而减弱;非晶薄带的磁感应效应变化幅度随磁场的增强而增大,随频率的升高而减小;与淬火态非晶薄带相比,退火可以提高非晶薄带的磁感应效应变化幅度,且经300℃×1h退火后非晶薄带的磁感应效应变化幅度最大,当测试频率为0.8MHz时,磁场为1412A/m时,淬火态非晶薄带的磁感应效应变化幅度为1.50V,经300℃×1h退火后非晶薄带的磁感应效应变化幅度为1.77V。
The influences of frequency, magnetic field and annealing process on the magnetic induction effect and the change of magnetic induction effect of Fe736Cu1Nb3Si13.5B9 amorphous alloy ribbons were studied. The results show the magnetic induction effect enhances with the frequency increasing and decreases with the magnetic field increasing; the change of magnetic induction effect enhances with the magnetic field increasing and decreases with the frequency increasing; the change of magnetic induction effect can be enhanced after annealing, whose maximum is after annealing at 300 ℃ for 1 h, at 0.8 MHz and 1412A/m, the change of magnetic induction effect at 300 ℃ for 1 h can reach 1.77V, but only 1.50 V for quenching state ribbons.
