In order to understand the interesting physico-chemical properties of Zr-based glassy metals, the combinatorial analysis of single crystal XRD for crystalline approximants and AXS-RMC of glassy metals is strongly required. This research project succeeded to demonstrate the structural features of a variety Mackay clusters around transition metal elements and the local structural features for Zr-based and Pd-based glassy metals. A series of AXS-RMC analysis revealed that the stability of glassy metals has no significant relationship with the probability of icosahedral structural units in thesamples.

为了了解锆基玻璃金属有趣的物理化学性质，强烈需要对玻璃金属的晶体近似的单晶 XRD 和 AXS-RMC 进行组合分析。该研究项目成功展示了围绕过渡金属元素的各种麦凯团簇的结构特征以及Zr基和Pd基玻璃金属的局部结构特征。一系列AXS-RMC分析表明，玻璃态金属的稳定性与样品中二十面体结构单元的概率没有显着关系。
