摘　　要：为研究Fe基合金薄带温度应力退火及回火特性,利用HP42494A阻抗分析仪得到Fe_(73.5)Cu_1Nb_3Si_(13.5)B_9非晶薄带应力退火及回火后的磁各向异性场,用位移传感器测量退火和回火的伸长量.分析了经11次回火过程后样品的磁各向异性场的剩余百分比与薄带伸长量剩余百分比的关系.结果发现:11次回火后,磁各向异性场的剩余百分比为25.3%,薄带伸长量的剩余百分比为78.7%,表明:回火不能完全消除应力退火感生的磁各向异性场,且薄带的伸长不能完全恢复.According to the longitudinal giant magneto-impedance effect curve of Fe73.5 Cu1Nb3Si13.5B9 ribbon samples which had been annealed and tempered 11 times, the magnetic anisotropy field was obtained, at the same time monitoring ribbon elongation under applied stress. Analysis of the experimental data obtained after tempering 11 times. The results showed that the residual magnetic anisotropy field was 25.3% and the residual elongation was 78.7%. It was concluded that multiple tempering could not eliminate entirely stress-induced magnetic anisotropy and ribbon elongation could not fully recover. It was suggested that the magnetic anisotro- py field induced by stress about 70% came from the residual stress and 30% came from creep elongation.
