Fig.2 Microstructures of Mg-Zn-Y alloy with LPSO structures before (a, b) and after (c) compression at room temperature
(a) low-magnification HAADF-STEM image showing the basal planes of LPSO structures and SFs enriched with Zn and Y atoms are parallel to the basal plane of the matrix in the Mg-Zn-Y alloy
(b) atomic-scale HAADF-STEM image showing AB'C'A building blocks (red lines) in the LPSO
(c) the multiple twins were triggered during compression, and they intersected with the SFs
