  • 本文叙述了用偏振中子衍射方法对Fe83B17非晶合金和中子衍射方法对Ni64B36非晶合金的结构研究。由实验数据计算了每种合金的偏干涉函数(PSF)Sij(Q),和偏简约径向分布函数Gij(r)。并得到原子短程结构上的各项参数。在此基础上,讨论了这一类非晶态合金的结构模型,计算了其一种模型简单单元的中子衍射散射强度,并和实验所得的结果作了比较。
    Neutron diffraction measurements have been made on metallic glasses Fe83B17 using polarized beam and on Ni64B36 using non-polarized beam. The partial structure factors Sij(Q) and partial reduced RDF for these two glasses are obtained from the scattering patterns, the atomic short range structural parameters are also obtained. These curves and parameters are discussed in relation to current models of metallic alloy glasses. The neutron scattering intensities of a simple model have been simulated and the results compared with those obtained from the experiments.
