Abstract
The angles between the zone axes of decagonal quasicrystals in two different Al–Mn alloys have been studied by means of precision tilt experiments in a transmission electron microscope. The results confirm that a tenfold symmetry axis is present in the reciprocal lattice. The angles between the principal axes in the decagonal phase do not coincide with those between the corresponding axes in the icosahedral phase. The presence of this distortion is independent of quenching rate and size of the decagonal quasicrystals.Keywords
