Figure 6

Phase fraction of face centered cubic (FCC) and hexagonal close packed (HCP) structures as a function of frequency for (a) 0.2 mm and (b) 0.6 mm shaking amplitudes. The insets to (a,b) show the frequency dependence of the angular shift and intensity variation of the peak from icosahedral (θ ≈ 116.5°) towards FCC/HCP (θ ≈ 120°) crystalline evolution for 0.2 mm and 0.6 mm shaking amplitudes, respectively.
