采用反常X射线散射(AXS)结合反向蒙特-卡罗(RMC)模拟研究了Zr 50 Ni 50非晶合金的结构。最近邻原子构型的拓扑特征清楚地表明,Ni和Zr之间的强化学相互作用打破了硬球致密无规堆积(DRPHS)模型中常见的二十面体状局部有序结构。然而,Zr50Ni50的结构没有显示出与晶体状化学短程有序(CSRO)相关的进一步特征。
Structure of Zr50Ni50 Amorphous Alloy Was Analyzed by Anomalous X-Ray Scattering (AXS) Coupled with Reverse Monte-Carlo (RMC) Simulation. Topological Features in the Nearest Neighbor Atomic Configuration Clearly Suggest that the Strong Chemical Interaction between Ni and Zr Breaks the Icosahedral-Like Local Ordering Structure Common in the Dense Random Packing of Hard Sphere (DRPHS) Model. Nevertheless, the Structure of Zr50Ni50 Shows No Further Features Related to the Crystal-Like Chemical Short Range Ordering (CSRO).
