Quasicrystals, which have long-range orientational order without translational symmetry, are incompatible with the theory of conventional crystals, which are characterized by periodic lattices and uniformly repeated unit cells. Reported here is a novel quasicrystal-related solid state observed in two Al-Cr-Fe-Si alloys, which can be described as a mosaic of aperiodically distributed unit tiles in translationally periodic structural blocks. This new type of material possesses the opposing features of both conventional crystals and quasicrystals, which might trigger wide interest in theory, experiments and the potential applications of this type of material.

与准晶体相关的镶嵌体，具有周期性晶格和非周期性瓷砖。

具有远距离取向顺序而没有平移对称性的准晶体与常规晶体的理论不兼容，常规晶体的特征在于周期性晶格和均匀重复的晶胞。此处报道的是在两种Al-Cr-Fe-Si合金中观察到的新型准晶体相关的固态，可以描述为非周期性分布的单位平铺在平移周期性结构块中的镶嵌。这种新型材料具有常规晶体和准晶体的相反特征，这可能会引起人们对这种类型的材料的理论，实验和潜在应用的广泛兴趣。
