摘要：

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