In this paper, [omega] phase in Al-Cu-Mg and Al-Cu-Mg-Ag is examined to determine the influence of silver addition on the [omega] precipitate structure and the effect of the large misfit normal to the [omega] plate habit plane on the interfacila structure. Using electron diffraction and HREM, no difference in [omega] structure could be discerned between the two alloys with and without Ag additions.
