Materials Letters, 233, 254-257. doi:10.1016/j.matlet.2018.09.002 | Journal: | Materials Letters | Abstract: | In this study, the atomic arrangement of the decagonal phase in a spark-plasma-sintered Al–Cr–Fe alloy has been studied by Cs-corrected high angle annular dark field scanning transmission electron microscopy (HAADF STEM) for the first time. We have found that three types of atomic clusters exist as basic structural units: star, flattened hexagon and decagon with an edge-length of 0.65 nm. These three types of units are linked to each other by sharing edges or inter-penetrating, with adjacent star clusters overlapping each other. The respective structural models of these structural units are proposed from the HAADF STEM images. | URI: | https://hdl.handle.net/10356/139106 | ISSN: | 0167-577X | DOI: | 10.1016/j.matlet.2018.09.002 | DOI (Related Dataset): | https://doi.org/10.21979/N9/A4FNPW | Rights: | © 2018 Elsevier B.V.
