Abstract

Microstructures of kink boundaries in a magnesium-zinc-yttrium (Mg-Zn-Y) alloy were observed by transmission electron microscopy. Wedge-shaped kinks with high angle kink boundaries have been found in Mg-Zn-Y alloys due to deformation of the long-period stacking ordered (LPSO) phase. It has been found that wedge-shaped kinks have several Zn/Y-rich sub-kink boundaries, since more dislocations are introduced in both hcp and fcc structures of the LPSO phase due to further compression.
