Abstract: We have observed a metallic solid (Al-14-at.%-Mn) with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations. Its diffraction spots are as sharp as those of crystals but cannot be indexed to any Bravais lattice. The solid is metastable and forms from the melt by a first-order transition.

Bond-orientational order in liquids and glasses
TL;DR: In this paper, the authors studied the bond-orientational order in molecular-dynamics simulations of supercooled liquids and in models of metallic glasses and found that the order is predominantly icosahedral, although there is also a cubic component which they attribute to the periodic boundary conditions.

TL;DR: In this article, the stability of a moving planar liquid-solid interface during unidirectional freezing of a dilute binary alloy is theoretically investigated by calculating the time dependence of the amplitude of a sinusoidal perturbation of infinitesimal amplitude introduced into the planar shape.
