Zhu State Key Laboratory of Solidification Processing %A Northwestern Ploytechnical University %A Xi''an %A China %J 金属学报(英文版) %D 2007 %I %X The microstructure formation and mechanical property involving icosahedral quasicrystal (I-phase)in the Y-rich Mg-Zn-Y alloy have been studied. The equilibrium formation of I-phase from the Y-richMg-Zn-Y melt is through a peritectic reaction between the Y-rich melt and the primary W-phase,which is discussed in detail. The independent nucleation and coupling growth mechanism betweenthe W-phase and the I-phase, from the melt, are revealed, which is significant for understandingthe peritectic reaction process involving icosahedral quasicrystal in the Mg-Zn-Y alloy. Themechanism of the quasicrystal phase strengthened magnesium alloys is also discussed here. %K KMg-Zn-Y %K icosahedral quasicrystal %K peritectic reaction %K mechanical property %K ALLOY %K ICOSAHEDRAL QUASICRYSTAL %K RICH %K PHASE %K INVOLVING %K MECHANICAL PROPERTY %K FORMATION %K icosahedral quasicrystal %K phase %K strengthened %K magnesium alloys %K significant %K reaction process %K independent %K nucleation %K coupling %K growth mechanism %K equilibrium %K peritectic %K melt
