Abstract

Icosahedral Al-Pd-Mn and decagonal Al-Ni-Co quasicrystals were investigated using small angle neutron scattering. Both isotropic and anisotropic scattering were observed. It is consistent with the existence of free volume due to dodecahedral and quasi-spherical voids in the icosahedral quasicrystal. In the decagonal specimens prismatic holes and chemical inhomogeneities seem to be responsible for scattering observed at small angles.
