利用广角X射线散射测量了金属玻璃TiCu,Zr_(3.12)Ni吸氢前后约化径向分布函数的变化.假定氢原子主要占据由Ti原子或Zr原子构成的四面体间隙,可以定量地解释第一峰的位移.对大γ处具有近似周期性的宽散峰也进行了讨论.
The changes in the reduced radial distribution function of metallicglasses TiCu and Zr_(3.12)Ni before and after hydriding have been measured using thewide-angle X-ray scattering. It is shown that if hydrogen atoms mainly occupy thetetrahedral interstices defined by four Ti or Zr atoms, the displacement of the firstpeak can be interpreted quantitatively. Broad peaks with approximate periodicity atlarger r range is also discussed.
