摘要：

Thermal relaxation effects on AlPdRe icosahedral quasicrystal samples quenched from high temperature have been studied. A systematic and rapid increase in electrical resistivity versus annealing temperature is seen below 700 degrees C, near which an abrupt change in reversibility behavior is also observed, while the samples retain the i-phase structure. Samples quenched from above 700 degrees C show relaxation time constants many orders of magnitude larger than those for metallic glasses. The unusual features observed are ascribed to the possibility of a structural transition in AlPdRe i alloys.
