Metallic Phase with Long-Range Orientational Order and No Translational Symmetry

Metallic Phase with Long-Range Orientational Order and No Translational Symmetry

A metallic solid (Al--14 at.% Mn) with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations, was observed. Its diffraction spots are as sharp as those of crystals but cannot be indexed to any Bravais lattice. The solid is metastab...

Description
Summary:A metallic solid (Al--14 at.% Mn) with long-range orientational order, but with icosahedral point group symmetry, which is inconsistent with lattice translations, was observed. 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. 12 ref.--AA(US).
