Abstract

Precipitation of long‐period stacking ordered (LPSO) structure in Mg–15Gd–0.8Zn–0.8Mn (wt%) alloy after solution treatment at 520 °C for 1 000 h has been investigated using high angle annular dark field scanning transmission electron microscopy (HAADF‐STEM). The stacking periodicity of the LPSO phase is lengthened 14‐fold along the c‐axis and the LPSO phase consists of Gd‐ and Zn‐enriched solute clustering. Detailed HAADF‐STEM imaging shows a clear evidence of a co‐segregation of Gd and Zn within a LPSO phase. This paper provides a better understanding of the interaction between Gd and Zn, which can, therefore, provide useful guidelines to develop high performance Mg alloys.
