Determination of interfacial atomic structure, misfits and energetics of Ω phase in Al―Cu―Mg―Ag alloy

The interfacial atomic structure and misfits of Omega precipitates formed in the face-centered cubic Al in the Al-Cu-Mg-Ag alloy have been determined by combining scanning transmission electron microscopy (STEM) Z-contrast imaging with chemical analysis and ab initio density functional theory (DFT)...
