摘　　要：采用铁芯测试仪测得合金样品的初始磁导率随温度的变化曲线,用磁化强度小角旋转法测量非晶及晶化合金条带的饱和磁致伸缩系数λs;研究了不同温度退火后Co64Fe11Nb5Si12B8合金的磁导率随温度的变化、磁性以及磁致伸缩系数;结果表明:合金在580、590℃热处理磁性变好的反常现象是由于磁致伸缩系数变小所致。Under different annealing temperatures, the magnetic properties, the saturation magnetostrictions, the correlation between the permeability μi and the temperature T（μi-T curves） for the Co64 Fe11 Nb5Si12 B8 alloy were investigated by the ballistic galvanometer , the small angle magnetization instrument and the core testing instrument. The experimental results show that the μi-T curves had three shapes; the better magnetic properties for the alloy are considered to be caused by the decrease in the saturation magnetostrictions annealed at 580, 590℃.
