Abstract
Partial isothermal sections of the Al-Pd-Co phase diagram at 1050 and 790 d egreesC are presented. In contrast to Al-Ni-Co no stable quasicrystals were found under the investigated conditions. Instead, at the compositions corr esponding to the high-Co limit of the Al-Ni-Co decagonal phase a periodic p hase closely related to the decagonal phase is formed. Orthorhombic "Al3Pd" , whose structure is known to resemble quasicrystals, extends up to 17 at.% Co and exhibits structural variations with composition. At the Al concentr ations slightly lower than Al3Pd(CD) several new ternary periodic phases we re found. (C) 2000 Elsevier Science B.V. All rights reserved.
