Plot of the Rietveld refinement of the powder XRD pattern of the Al69.5Cu20.0Cr10.5 alloy showing the observed XRD profile (red filled circles), calculated profile (black solid line) and difference between them (blue solid line). The vertical bars refer to the calculated peak positions of the ϕ phase (upper blue bars) and Al3Cu4 (bottom red bars). |
