摘要

用共振粉末衍射法研究了Zr-Nb- al体系中三元μ相在Zr边和Nb- k边的分布，确定了这三种物质在晶体结构5个不同位置上的分布。并与其他体系中μ相的结果进行了比较。在精化中使用两个或三个数据集获得的结果的比较允许对方法进行讨论。

Mixed site occupancies in μ-Zr-Nb-Al by resonant powder diffraction

The ternary μ phase in the system Zr-Nb-Al has been studied by resonant powder diffraction at the Zr and Nb K-edges in order to determine the distribution of the three species on the five different sites of the crystal structure. The results are presented in comparison with those obtained for the μ phase in other systems. The comparison of the results obtained using two or three data sets in the refinement allows a discussion on the methodology.
