摘要	The effects of Zn addition on the microstructure, aging behavior and mechanical properties of as-cast Mg-Dy alloy were investigated. The results show that the lamellar Mg12ZnDy phase with a 18R-type long period stacking ordered (LPSO) structure and coarse Mg3Zn3Dy2 phase precipitate in the alloy, respectively, when 0.5% and 1% (mole fraction) Zn are added. Simultaneously, the grains of the alloy are refined with increasing Zn content. After solution heat treatment, the 18R-type LPSO phase transforms to a strip-like 14H-type LPSO structure distributing in the grain interior. In addition, the (Mg, Zn)xDy phase forms and the volume fraction of Mg3Zn3Dy2 phase decreases. 0.5% Zn addition improves the aging behavior and strengthens the tensile strengths at room temperature and 200. ©, 2015, Central South University of Technology.
