摘要	Dislocations and local chemistries around them in plastically deformed long-period stacking ordered phases in a Mg-Zn-Y alloy have been investigated by the combination of atomic resolution electron microscopy imaging and nano-probe energy dispersive X-ray spectroscopy measurements. Zn/Y Cottrell atmospheres were observed along dislocations at kink boundaries and individual dislocations in bulk long-period stacking ordered phase. Evidence for unpinning of dislocations from Cottrell atmospheres was also observed. A binding energy of about 0.05 eV is estimated between the dislocations and solute atoms trapped within the atmospheres. (C) 2016 Elsevier Ltd. All rights reserved.
