Quasicrystal structure in Al─Cu─Fe annealed alloy

open access: yesPhilosophical Magazine Letters, 1988
Abstract Powder X-ray diffraction, electron diffraction and electron microscopic experiments, including high-resolution electron microscopy, have revealed that the Al─Cu─Fe icosahedral phase has a higher degree of structural perfection than other known icosahedral phases.
