Abstract

Decagonal quasicrystals in Zn-Mg-RE systems (RE = rare earth) have been studied for their composition and stability. The decagonal phase was shown to have the composition Zn58Mg4oDy2in the Zn-Mg-Dy system. This phase became a major phase after annealing and thus is apparently thermodynamically stable. Further, the decagonal phase was observed for RE = Y, Dy, Ho, Er, Tm and Lu.o All these RE elements have Goldschmidt atomic diameters smaller than 3.55 A, suggesting that the atomic diameter is an intrinsic parameter in stabilizing the decagonal phase.
