研究了挤压Mg-2Zn-xY (x=0.5,1,2,at％)合金在半固态等温处理过程中的微观组织演变规律.结果表明:3种Mg-2Zn-xY合金中,挤压Mg-2Zn-1Y合金中α-Mg基体晶粒尺寸晟小,挤压Mg-2Zn-2Y合金中出现了大量的孪晶;当半固态等温时间为10 min时,随着等温温度的升高,...

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-rich Mg-Zn-Y melt is through a peritectic reaction between the Y-rich melt and the primary W-phase, which i...
