Figure 7
X-ray powder diffraction pattern (CuKα radiation) of the sample recovered from 5 GPa and 1673 K (a). Grey lines are used to mark peaks representative of i-AlCuFe that can be indexed according to Bindi et al.6 (see also Figure S1b). b) A reconstructed precession image down the five-fold symmetry axis obtained using the collected single-crystal X-ray reflections from a fragment of the same sample as in (a) compatible with icosahedral symmetry.
