Abstract
We show that the α-(AlMnSi) crystal structure is closely (and systematically) related to that of the icosahedral Al-Mn-Si alloys. Using a modification of the ‘‘projection’’ method of generating icosahedral structures from six-dimensional lattices, we find a simple description of the α-(AlMnSi) structure. This structure, and (we conjecture) the icosahedral one, can also be described as a packing of 54-atom icosahedral clusters.Keywords
