Full single-crystal X-ray diffraction data sets were collected of 31 samples annealed at 900 °C. Based on reciprocal space reconstructions of the imaging-plate-scanner data, the variation in Bragg as well as in diffuse scattering is discussed in detail. The samples were also characterized metallographically, by powder X-ray diffraction, differential thermal analysis and energy-dispersive X-ray spectroscopy. The (quasi)lattice parameters vary smoothly over the stability range of decagonal Al71.5Co28.5—xNix (8 ≤ x ≤ 20). A smooth variation is also observed for the diffuse scattering related to the ≈8 Å superstructure. These observations indicate a continuous ordering process at 900 °C from the basic Co-rich phase via the type II and type I superstructures to the basic Ni-rich phase. © 2004 Oldenbourg Wissenschaftsverlag GmbH Crystallography nationallicence Inorganic chemistry nationallicence Organic chemistry nationallicence Katrych Sergiy aut Steurer Walter aut Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/10(2004-10-01), 606-613 2194-4946 219:10<606 2004 219 zkri https://doi.org/10.1524/zkri.219.10.606.50824 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zkri.219.10.606.50824 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Katrych Sergiy aut NATIONALLICENCE 700 1- Steurer Walter aut NATIONALLICENCE 773 0- Zeitschrift für Kristallographie - Crystalline Materials De Gruyter Oldenbourg 219/10(2004-10-01), 606-613 2194-4946 219:10<606 2004 219 zkri CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
