利用实空间对分布和径向分布函数研究了Ag替代Cu对Cu_55Zr_45、Cu_45Zr_45Ag_10和Cu_35Zr_45Ag_20非晶合金结构特征的影响。在同步加速器光束中获得的实验X射线衍射数据通过傅里叶变换处理导出对和径向分布函数。这些结果表明,该合金中在约 2.5 nm 距离内保持一定程度的中程有序。研究表明,与二元 Cu-Zr 合金相比,Ag 的添加导致形成更均匀的局部原子结构,这可以被认为是该合金玻璃形成能力提高的原因。
The effect of Ag substituting Cu on the structural features of the Cu_55Zr_45, Cu_45Zr_45Ag_10, and Cu_35Zr_45Ag_20 glassy alloys was studied using the real-space pair distribution and radial distribution functions. The experimental x-ray diffraction data obtained in a synchrotron beam were used to derive pair and radial distribution functions through Fourier transformation processing. These results suggest that a certain degree of medium-range order in this alloy is maintained up to about 2.5 nm distance. It is suggested that the addition of Ag causes formation of a more homogeneous local atomic structure compared with that of a binary Cu–Zr alloy, which could be considered as a reason for the improved glass-forming ability of this alloy.
