The precipitation sequence in Al-Mg-Si alloy is generally accepted as supersaturated solid solution →GP-zone → β'' →β' →β (Mg2Si). The effect of Ag or Cu in Al-Mg-Si alloy has been reported in a previous work [2-3]. There are few reports about the effect of Ag or Cu on the metastable phase and equilibrium phase in this alloy the system. Hexagonal plate like β-phase and Q-phase were observed in the Cu added alloy. This hexagonal-shaped β-phase has a unique orientation relationship to the Al matrix. This work was performed to compare the shape effect of the additional elements on the equilibrium phase. The hexagonal shape precipitate was observed both in Cu or Ag added alloys aged at 673K.
