摘要：
It has been shown that three types of structures of monoctinic Al13Fe4, decagonal Al72Ni20Co8 with 2-nm mirror-symmetric cluster-column and decagonal Al70Ni15Fe15 with 2-nm 5-fold-symmettic cluster-column, have pentagonal columns, which are composed of common atom-clusters with different stacking sequences. The Al13Fe4 structure and structural models of the two decagonal quasicrystals are summarized. The structural relation among them is discussed. (C) 2002 Elsevier Science BV All rights reserved.
