摘要：

Inherent low strength is the major limitation of Mg-Li alloys. Through precise control of precipitates, the cast Mg-8Li-3Al-2Zn alloy obtained a high specific ultimate tensile strength of 213 kN<middle dot>m<middle dot>kg-1. Precipitates evolution during non-isothermal aging was investigated: strip-like Mg3(Al, Zn) in beta-Li -> globular Mg3(Al, Zn) in beta-Li -> Mg/Li(Al, Zn) core-shell and nanoscale rod-like Mg3(Al, Zn) in beta-Li + Laves phase in alpha-Mg. The short-term high-temperature aging results in the precipitation of Laves phase in alpha-Mg and the formation of nanoscale rod-like Mg3(Al, Zn) and Mg/Li(Al, Zn) core-shell phase in beta-Li, achieving synergistic strengthening of the dual matrix phases.
