Polytypes of long-period stacking structures synchronized with chemical order in a dilute Mg-Zn-Y alloy

E. Abe, A. Ono, T. Itoi +2

A series of structural polytypes formed in an Mg-1at.%Zn-2at.%Y alloy has been identified, which are reasonably viewed as long-period stacking derivatives of the hcp Mg structure w…
