EFFECT OF HYDROGEN ON THE MAGNETISM AND YOUNG''''S MODULUS OF Fe BASED AND Fe-Ni BASED METALLIC GLASSES
氢对Fe基和Fe-Ni基金属玻璃磁性和杨氏模量的影响

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.
