摘　　要：使用大角转动张力磁化法研究了金属玻璃Fe39Ni39Si8B12Mn2渗氢后时效过程中磁化曲线和饱和磁致伸缩系数的变化。结果表明:含氢的Fe39Ni39Si8B12Mn2金属玻璃饱和磁化强度下降,而各向异性常数增加,相应饱和磁伸系数减小。The variations of the saturation magnetostriction constant and the magnetization-flux of the metallic glass Fe39Ni39Si8Bl2Mn2 were studied using the tension-magnetization with a large angles rotation during aging at room temperature after charging hydrogen. The results show that with the decrease of saturation magnetization, the increase of anisotropic constant and the smaller value of saturation magneto-striction constant are induced by hydrogen in metallic glass.
