With addition of Aluminum (Al) in Mg-15Li alloy, the compressive yield strength is continuously increased and density is slightly decreased. This improved mechanical property is mainly attributed to the precipitation of Al-Li intermetallic compounds into the beta-phase and grain size refinement of beta-phase. Accordingly, lightweight and high specific strength Mg-Li-Al alloys were developed successfully via proper addition of Al contents, resulted from favorable microstructural evolution.
