First-Principles Calculations of Oxygen-Dislocation Interaction in Magnesium

First-Principles Calculations of Oxygen-Dislocation Interaction in Magnesium

The interaction between interstitial oxygen atoms and <a>-type screw dislocations was investigated via first-principles calculations to elucidate the effect of oxygen solutes on the deformation behaviors of Mg. The results show that repulsive interactions exist between basal screw disl...
