Abstract

Crystals of the α-(AlMnSi) (aluminium manganese silicon alloy, Al4Mn1.01Si0.74) cubic 1/1 approximant phase for the icosahedral quasi-crystal were prepared from an Al72Mn16Si12 alloy under an argon atmosphere. The structure is reproduced by the connection of two large atom clusters with icosahedral symmetry (a Mackay icosahedron and a double-Mackay icosahedron) [Yang (1988). Philos. Mag. B58, 47-57]. Si and Mn atoms are proposed to constitute icosahedral arrangements in the atom clusters. The crystal structure of α-(AlMnSi) was determined previously by Cooper & Robinson.
