Abstract
After an introduction to quasi crystals, special attention is paid to icosahedral Al6(Cr0.7Fe0.3) and decagonal Al7(Mn1−xFex)2. These alloys have been studied with Mössbauer-effect spectroscopy and diffraction techniques. Isomer-shift and quadrupole-splitting data on the icosahedral alloys are successfully described with a Mackay cluster. The X-ray diffractogram of pure decagonal Al7(Mn1−xFex)2, x = 0 and 0.3, has been indexed with a basis-vector set that is closely related to the icosahedral set.Keywords
