英文摘要	Due to unique precipitation behavior, magnesium-rare earth (Mg-RE) alloys exhibit excellent strength. However, owing to the blocking effect of solid solute atoms on the slipping of dislocations, the plasticity of Mg-RE alloys becomes poor. In this work, HPT followed by solution and aging treatment is used to produce laminate heterogeneous Mg-Y alloys by sandwiching a hard layer and two soft layers. Specially, the interface transition region shows a gradient distribution of Y concentration and precipitation. The sandwich Mg-Y alloy attains an enhanced strength-plasticity synergy.
