Description

Stoichiometric composition and formation process of the icosahedral phase in Zn endash Mg endash Y system have been studied. The icosahedral phase exhibits a stoichiometric composition in the vicinity of Zn60Mg30Y10. During cooling, a (Zn,Mg)5Y phase primarily crystallizes from the melt at ∼960 K and then undergoes to a peritectic reaction with the residual Mg-enriched melt (∼820 K) to form the icosahedral phase. The melt with a constant composition close to Mg7Zn3 is in equilibrium with the (Zn,Mg)5Y phase above the peritectic temperature in a wide compositional range. copyright 1997 Materials Research Society
