摘要：
In this work, friction stir additive manufacturing was successfully performed to fabricate the dual-phase Mg-Li-Al-Zn magnesium alloy. A fine-grained microstructure decorated by uniformly dispersed precipitates was observed in the stir zone. Through the combined effects of grain refinement and solid solution strengthening, the friction stir additive manufactured Mg-Li-Al-Zn alloy exhibited the synergistic enhancement of strength, ductility, and corrosion resistance.
