Abstract
Structural and electrical transport properties of thermodynamically stable quasicrystalline Al-Cu-Fe alloys have been studied using X-ray diffraction, Mössbauer spectroscopy and d.c. electrical resistivity measurements. These results are compared with measurements on analogous crystalline and rapidly solidified alloys. The electrical resistivity of stable Al-Cu-Fe alloys is anomalously (∼ 3000 μΩ cm) high compared to most disordered alloys. The temperature dependence of resistivity of icosahedral Al63Cu25Fe12 can be described by a structural Kondo effect model.
