Accumulative roll bonding (ARB) technique is used to manufacture fine-grained and high-strength Mg-8Li-3Al-1Zn alloy. Then, investigate the microstructure and mechanical properties. Results show that, the ARB-processed sheet possesses good bonding performance. The ARB refines the grains and causes the phase distribution to be scattered. With the increase of ARB passes, the sigma(0.2,) sigma(b), and hardness values are enhanced, whereas the elongation value first decreases, then slightly increases with the increase of ARB passes. The ARB5 sheet possesses the smallest grain size (about 3 mu m) and the best comprehensive mechanical properties, the tensile strength, elongation, and hardness are 287.02MPa, 12.5%, and 77.2 HV0.05, respectively.
