Universal structure unit for AlLiCu, AlMnSi, and AlFeCu quasicrystals
Dmitrienko V. E.
It is suggested that the structure of icosahedral quasicrystals is the result of dodecahedral arrangement of closest atoms observed in the AlLiCu, AlMnSi, and AlFeCu alloys. New cubic approximants of icosahedral quasicrystals are found. Unconventional projection scheme for construction of quasicrystals and their crystal approximants is discussed.
