First-principles study on the effects of V, Nb, Cd, Ag, Ge and Sb doped in Al2CuMg phase of Al–Zn–Mg–Cu alloy

The S phase (Al2CuMg) is an important strengthening phase for the Al–Zn–Cu–Mg alloys, which are widely used in the aerospace and transportation industries. First-principles calculations based on th...
