摘要
采用单辊法制备宽3.2 mm厚25μm的Fe73.5Cu1Nb3S i13.5B9非晶薄带,利用4294A型阻抗分析仪测试了非晶薄带的应力阻抗效应。结果表明:当测试频率较低时,双层Fe73.5Cu1Nb3S i13.5B9非晶薄带的应力阻抗效应较弱,随着频率的升高,双层Fe73.5Cu1Nb3S i13.5B9非晶薄带的应力阻抗效应出现了明显的增强;多层非晶薄带的应力阻抗效应比单层的小。
Fe73.5Cu1Nb3Si13.5B9 amorphous alloy ribbons with 25 μm thickness and 3.2 mm width were manufactured by single - roller method. The stress impedance effect of ribbons was investigated by 4294A impedance analyzer. The result showed when the test frequency was lower the stress impedance effect of ribbons was smaller, the stress impedance effect of ribbons appeared obvious strengthening along with the elevating frequency. The stress impedance effect of multi - layered amorphous ribbons was smaller than the single -layer.
