摘要：
Through investigating the mechanical properties of three kinds of Mg-Li-Zn-Y alloys, a strengthening method, i.e. introducing I-phase Mg(3)Zn(6)y, icosahedral quasicrystal structure) in the matrix of Mg-Li alloys, for as-extruded Mg-Li alloys has been demonstrated. The tensile results indicate that I-phase can effectively strengthen the alloys. The substantial enhancement of strength has been explained by microstructure changes. (c) 2007 Acta Materialia Inc.
