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 l’or producing fine grains was applied which concluded solution treatment at 350 , cold rolling with 600/n thickness reduction and 250 annealing, successively. Key words: Mg-Li alloy: beryllium; scandium; solid solution strengthening.
