The structure of Zr(60)Cu(20)Fe(20) metallic glass has been studied with high-energy x-ray diffraction, neutron diffraction and extended x-ray absorption spectroscopy and modelled with the reverse Monte Carlo simulation technique. It is found that Cu and Fe atoms prefer Zr as a nearest neighbour. The mean interatomic distance between Cu/Fe and Zr atoms in the glass is remarkably shorter than the sum of the respective atomic radii. The coordination numbers for Cu/Fe-Cu/Fe pairs are very close to each other, suggesting a regular distribution of Cu and Fe atoms in the Zr(60)Cu(20)Fe(20) metallic glass.
采用高能 X 射线衍射、中子衍射和扩展 X 射线吸收光谱对 Zr(60)Cu(20)Fe(20)金属玻璃的结构进行了研究，并采用反向蒙特卡罗模拟技术对其进行了建模。结果表明，Cu 和 Fe 原子优先与 Zr 形成近邻原子。玻璃中 Cu/Fe 和 Zr 原子之间的平均原子间距明显短于各自原子半径之和。Cu/Fe-Cu/Fe 对之间的配位数非常接近，表明 Cu 和 Fe 原子在 Zr(60)Cu(20)Fe(20)金属玻璃中呈规则分布。
