(a) Al67Cu20Fe5Cr8 composition on the Al70CuFeCr library. (b) Diffractogram of the arc-melted Al67Cu20Fe5Cr8 alloy after annealing at 600 °C. (c) SEM-BSE micrograph of the annealed sample showing the presence of two phases: decagonal quasicrystal (phase #1) and an Al-Cu-rich phase (phase #2). (d) SAED pattern of the quasicrystalline phase, displaying ten-fold rotational symmetry. (e) Columnar morphology of a single decagonal quasicrystal. This phase typically grows in such a columnar fashion along the ten-fold axis of symmetry.
