Abstract
We report the characterization of an ordered non-crystalline isotropic metallic solid that, during rapid cooling of an Al-Fe-Si melt, forms by nucleation, followed by growth along a moving interface between the solid and melt with partitioning of the chemical elements. We determine experimentally that this is not a polycrystalline composite with nanometer sized grains, and conclude that this may be a new kind of structure: an atomically ordered, isotropic, non-crystalline solid, possessing no long-range translational symmetry.
