Figure 1
Basic structural information for decagonal Al60Cr20Fe10Si10 viewed along the tenfold zone axis. (a) Selected-area electron diffraction pattern of the DQC taken at 800°C. The diffraction pattern exhibits obvious tenfold symmetry, as shown by the yellow circles. (b) HRTEM image of the DQC observed at 800°C. (c) The fast Fourier transform of (b), which also exhibits the features of the DQC. (d), (e) Enlarged HRTEM images of the DQC at 800°C with the structural blocks depicted by polygons (e), and with the ∼2 nm D clusters emphasized (the same color indicates the same type of D cluster). (f), (g) Atomic resolution HAADF-STEM images of the DQC with the structural blocks depicted as polygons (f), and with the ∼2 nm D clusters emphasized in (g). The same color indicates the same type of D cluster. (h), (i) Enlarged images of two typical D clusters: D2H+B in (h) and D3H+BT in (i). |
