CLUSTER STRUCTURE OF THE SURFACE OF Al65Cu20Fe15 ALLOY IN THE QUASICRYSTALLINE AND LIQUID STATE

The atomic structure of an alloy is mainly affected by its electronic structure. The studies of the electronic structure of Al65Cu20Fe15 in both the liquid and quasicrystalline state show that the surface of the sample contains clusters with strong hybridized bonds between atoms which are similar in the liquid and quasicrystalline state. This fact confirms qualitatively the concept of cluster structure of quasicrystals.
