在90K以上测量了具有宽过冷区的三元ti37zr12cu51和四元Ti34Zr11Cu47Ni8玻璃合金的氢致内摩擦行为（也表示为（Ti0.37Zr0.12Cu0.51）92Ni8）。结果表明，随氢含量的增加，它们呈现出一个宽峰。随着氢含量的增加，两种非晶合金的峰值内耗增大，峰值温度降低。需要注意的是，在内耗峰的氢含量依赖性上，季系ti34zr11cu47ni8非晶合金的内耗峰要大于三元系ti37zr12cu51非晶合金。这是由于加入Ni后局部原子排列发生变化，即三元向四元转变，导致局部应变各向异性增加所致。另一方面，峰温的变化对氢含量的依赖关系没有明显的影响，这表明变化不仅改变了活化能，而且改变了弛豫过程中的频率因子（指前因子）。
Hydrogen-induced internal friction behavior of ternary Ti37Zr12Cu51and quaternary Ti34Zr11Cu47Ni8, which is also expressed by (Ti0.37Zr0.12Cu0.51)92Ni8, glassy alloys with a wide supercooling region have been investigated by measuring temperature dependence of internal friction above 90K. It is found that they show a broad peak depending hydrogen content. With increasing hydrogen content, the peak internal friction of both glassy alloys increases, while the peak temperature decreases. It should be noted that the peak internal friction of quaternary Ti34Zr11Cu47Ni8glassy alloys are larger than that of ternary Ti37Zr12Cu51glassy alloys in the hydrogen content dependence of the peak internal friction. This is attributable to the increase of local strain anisotropy due to the change of local atomic arrangement when adding Ni, i.e. the change from ternary to quaternary. On the other hand, there are no distinguished effects of the change on the hydrogen content dependence of the peak temperature, suggesting changes not only the activation energy but also the frequency factor (pre-exponential factor) in the relaxation process by the change.
