Abstract

We note that the electron per atom ratios in the known quasicrystal alloys of simple and noble metals obey rather accurately the Hume-Rothery-type relations which are characteristic for the "band" mechanism of the structural stability. If this mechanism is pronounced in the quasicrystal alloy then a number of its characteristics such as thermopower, shear constant, low-temperature thermal expansion etc. must vary sharply and peculiarly with the alloy composition. Thus experimental investigations of such concentration dependences can provide direct information on the importance of the bandstructure effects in properties of quasicrystals.
