Abstract
The effect of annealing (up to 750°C) on the structural perfection of stable quasicrystals has been studied, for the first time, in large grains of the icosahedral Al–Pd–Mn phase. This study was performed by combined synchrotron X-ray diffractometry and imaging techniques. It has revealed that the quasicrystalline quality improves as long as no precipitates are formed. The improvement was mainly ascribed to the relaxation of the strain field around voids, which are often observed in quasicrystals after growth.
