Abstract:Pioneering work on Sc or/and Be added Mg-Li alloys with refined grains was initiated. Various rolling-based thermo-mechanical treatments on these Mg-Li alloys were carried out. Four Mg-Li alloys were prepared by vacuum melting process. A unique route for producing fine grains was applied which concluded solution treatment at 350 °C, cold rolling with 60% thickness reduction and 250 °C annealing, successively.
Key words: Mg-Li alloy; beryllium; scandium; solid solution strengthening
