Abstract

18R long-period stacking ordered (LPSO) structure was introduced into Mg-Li alloys. For the investigated Mg-8Li-6Y-2Zn alloy, LPSO phase cannot be formed in the as-cast state as Mg-Y-Zn alloys, but it can be transformed from (Mg,Zn)₂₄Y₅ phase via heat treatment at 500 °C. Tensile test results indicate that the formation of 18R LPSO phase can effectively improve both the strength and plasticity of extruded Mg-8Li-6Y-2Zn alloy.
