In the literature the formation of domains in d-phases is well documented by direct electron microscopy observations. Compared to this 'local' method, diffraction investigations provide a more 'global' structural insight. Various kinds of domains in decagonal quasicrystals are discussed by extending the theory of domain scattering of conventional crystals. Peculiar diffraction phenomena in decagonal Al-Ni-Co phases are compared to theoretical predictions of the domain scattering theory. (C) 2002 Elsevier Science B.V. All rights reserved.
