Abstract

The packing features of Mackay and pseudo Mackay clusters in Al based approximants to icosahedral phases are surveyed. The cubic approximants of α-AlMnSi, AlReSi, and α- (Al,Si)CuFe indicate typical Mackay clusters composed by the dense icosahedral shell packing. On the other hand, the cubic approximants of α-AlCuRu and α-(Al,Si)CuFe and the non-cubic approximants of Ir₉Al₂₈, χ-AlPdRe, and R-AlPdCo shows so-called pseudo Mackay clusters in which the icosahedral packing feature is disappeared at their first shells. The distorted first shells represent a variation of pseudo Mackay clusters, which could be classified into three subgroups based on the symmetry.
