摘要：

We have found nanoscale quasicrystal-like structural states exhibiting pseudotenfold nanobeam electron-diffraction patterns in the course of nanocrystallization process of an Fe23B6 structure in an (Fe0.5Co0.5)(72)B20Si4Nb4 metallic glass. An existence of the intermediate states between the quasicrystal-like and Fe23B6 structures indicates that the quasicrystal-like structure is approximate to the Fe(23)B(6)structure including no icosahedral atomic arrangement. The pseudotenfold electron-diffraction patterns are understood from a combination of three types of tiles found in the Fe23B6 structure. The three types of tiles can produce decagonal units which do not have any icosahedral atomic arrangement.
