Abstract
From an electron-diffraction study the crystalline c-phase, observed together with the quasicrystals in an Al─Li─Cu─Mg alloy, has been analysed as exhibiting an almost perfect icosahedral symmetry. Orientation relationships with quasicrystals are determined and serve to define a new class of approximant structures, including, beyond the c-phase, the Ti2 Ni and Ti2 Fe structures.Keywords
