【摘要】 采用单辊法制备了宽4.5 mm、厚25μm的Fe73.5Cu1Nb3Si13.5B9非晶带材,并进行热处理以消除带材的残余内应力,利用4294A型阻抗分析仪测试了非晶带材的应力阻抗效应.结果表明:当测试频率低于20 MHz时,FeCuNbSiB非晶带材的应力阻抗效应较弱,随着测试频率的升高,材料的应力阻抗效应出现了明显的增强;热处理后非晶带材的应力阻抗效应增强,且随着热处理温度的升高而增强.更多还原

【Abstract】 FeCuNbSiB amorphous alloy’s strips with 25μm thickness and 4.5mm width are manufactured by single-roller method.The stress impedance effect is investigated by 4294A impedance analyzer.And carries on the heat treatment to eliminate the remaining stress.The result show when the test frequency is lower than 20 MHz,the FeCuNbSiB crystalless strip stress impedance effect is smaller,along with frequency increasing,the crystalless strip stress impedance effect appeared obviously strengthening;the crystalless strip stress impedance effect increase after the heat treatment,also elevates the stress impedance effect increase along with the heat treatment temperature.更多还原
