摘 要：Microstructure of as-cast and extruded Mg-8Li-1Al-1Y alloy specimens was analyzed with OM,SEM and XRD.Results show that as-cast specimens are composed of α phase（Mg）,β phase（Li） and rod-like Al2Y compound.In the extruded specimens,the microstructure is refined and the β phase has the effect of coordination during deformation.After extruding process,the Al2Y compound distributes evenly in the extruding direction.The results of mechanical properties tests show that the strength and elongation are both improved after extruding deformation.
