Disorder in Al-Li-Cu and Al-Mn-Si Icosahedral Alloys

Faceted dendrites of icosahedral Al$_{6}$Li$_{3}$Cu have been studied by high-resolution x-ray scattering. The samples display long-range icosahedral symmetry both in their diffraction patterns and in their macroscopic morphology. Despite the appearance of well-defined facets, the samples have a hig...
