Abstract
High resolution synchrotron x-ray data of near-Bragg diffuse scattering from decagonal Al71.5Ni23Fe5quasicrystals was recorded. A significant dependence on Qbotwas not observed, a dominant phasonic origin can thus be ruled out. An analysis in frame of a TDS theory gives an unlikely ratio of elastic constants c66/c11=4.0. Moreover, subsequent measurements up to 720 K do not reveal a pronounced intensity increase. Predictions of a theory of Huang diffuse scattering, however, nicely match the anisotropy of the measured data.
