采用反常X射线散射结合逆蒙特卡罗模拟研究了Zr 80 Pt 20 非晶合金的短程和中程有序结构。 Pt 更喜欢构建具有独特化学和拓扑短程有序性的富 Zr 二十面体配合物。本分析还揭示了与衍射曲线中 17 nm−1 处的前峰信号相对应的 Pt-Pt 对的中程有序性。 Pt 周围的化学和拓扑特征以及键合结构与 α-AlMnSi 近似相中 Mn 的化学和拓扑特征非常吻合。
The short-and medium-range ordering structure in Zr 80 Pt 20 amorphous alloy has been investigated by anomalous X-ray scattering coupled with reverse Monte-Carlo simulation. Pt prefers to construct a Zr-rich icosahedral complex with unique chemical and topological short-range ordering. The present analysis also revealed the medium-range ordering of Pt-Pt pairs corresponding to the pre-peak signal at 17 nm− 1 in the diffraction profile. The chemical and topological features around Pt and bonding structure correspond well with those of Mn in the approximant phase of α-AlMnSi.
