Villars和Calvert关于伪二元和三元相结构的经验数据库通过使用最近提出的Mendeleev数M在有限数量的二维图中进行排序，Mendeleev数M对于周期表中的每个元素都具有唯一值。伪双星的特征是平均门捷列夫数MA和MB。AB和AB 3化学计量的结构图（MA，MB）分别被发现显示类似的结构稳定的领域的纯二元。大多数不含H、C、N或O的三元结构类型的相（每个相具有多于一种代表性化合物）可以仅在七个二维图中显示和分离。硼化物和硫属化物结构类型各需要两个，其余三元相需要另外三个。这些图的设计新合金的重要性进行了强调。MST/814
The empirical database of Villars and Calvert on the structures of pseudobinary and ternary phases is ordered within a limited number of two dimensional plots by using the recently proposed Mendeleev number M, which takes a unique value for each element in the periodic table. The pseudobinaries are characterised by average Mendeleev numbers MA and MB. The structure maps (MA, MB) for the AB and AB3 stoichiometries respectively are found to display similar domains of structural stability as those of the pure binaries. Most of the non H, C, N, or O containing phases of ternary structure type having more than one representative compound each can be displayed and separated within only seven two dimensional plots. Two each are required for the boride and chalcogenide structure types and a further three for the remaining ternary phases. The importance of these plots for the design of new alloys is stressed.
