Abstract
Three structurally distinct states (amorphous, crystalline, and quasicrystalline) of Al65Cu20Fe15 and neighboring compositions, have been observed. A new metastable state. Intermediate between the amorphous and the quasicrystalline states, has been found. Mössbauer-effect measurements on these samples Al65Cu20xFe15+x (−10≤x≤ 10, at.%) In the three different states show that the differences in the effective isomer shifts and quadrupole splittings among the three states are small despile diametrically different structures.
