摘要：

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. Mossbauer-effect measurements on these samples Al65Cu20xFe15+x (-10 less-than-or-equal-to x less-than-or-equal-to 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 despite diametrically different structures.
