Structural changes of melt-spun AlCuFe icosahedral phase after heat treatments have been studied by X-ray powder diffraction. The widths of the diffraction peaks for the icosahedral phase in Al65Cu20Fe15are much reduced by annealing at temperatures above 600 °C and become comparable to the peak width of the f.c.c. Al standard sample for the sample annealed at 820 °C. In contrast, in the case of Al65Cu22Fe13, the peaks are observed to distort remarkably by annealing around 600 °C, which is attributable to the generation of a rhombohedral-type approximant crystalline phase.
