摘要 使用大角转动张力磁化法研究了金属玻璃 Fe_(80)Si_4B_4C_7,Fe_(39)Ni_(39)Si_8B_(12)Mn_2和(Fe_(30)Ni_(20))_(78)Si_(?)B_(14)三种样品渗氢及室温时效中磁化曲线和磁致伸缩系数λ_s 的变化,用动态测量方法研究了以上样品杨氏模量的变化。结果表明,含氢的金属玻璃饱和磁化强度 M:下降,而各向异性常数增大,相应饱和磁致伸缩系数λ(?)减小,同时杨氏模量降低。 The variations of the saturation magnetostriction constantand the magnetization-flux of the metallic glasses Fe_(80) Si_4B_(14)C_2,Fe_(39) Ni_(39)-Si_8B_(12)MN_2 and (Fe_(80) Ni_(20))_(78) Si_8 B_(14)were studied by using the tension-magne-tization with a large angle rotation,and the variation of Young's modulus ofthese samples was also studied during the aging at room temperature aftercharging hydrogen.The results show that the saturation magnetizations of themetallic glasses containing hydrogen decrease and its anisotropic constants in-crease,consequently,the values of its saturation magnetostriction constantsbecome small,furthermore,its Young's modulus decreases.
