摘要

Abstract

The growth

deformation

and extrinsic faults in binary Mg–X alloys are investigated via first-principles calculations. Here

the alloying elements X include Al

and Zr. In addition to stacking fault energies

the effect of the elements on the bond structure of Mg are studied in term of electron localization morphology. It is observed that rod-like directional bonds in non-fault planes transform into tetrahedral morphologies in fault planes and are strengthened by addition of Zn and Al

but weakened by Na.
