Silver additions can modify the formation of the ternary phases in Al-Cu-Mg alloys. In this respect, the phase diagram in the Al-rich region of this quaternary system is of interest. [2008Gab] studied the effect of small additions of Ag on the phase equilibria of this system in the Al-rich region. Earlier, [1997Lim2] computed the phase equilibria in the Al-rich region.
