Co-alloying effects on the site preference and the elastic properties of γ′-Ni3Al from first-principles calculations

The influences of co-alloying atom pairs Ta–X (X: Ta, Mo, W, Cr, Co, and Re) on the site preference and elastic properties of γ′-Ni3Al precipitate phase were studied using first-principles calculations, and the underlying mechanism for the strengthening effect is determined. It is found that the sit...
