Abstract

The precipitation of Ω-phase {111}α plates in the Al–Cu–Mg alloy has been investigated at a Cu/Mg ratio > 10 and low Si content. Unlike Al–Cu–Mg alloys containing Ag, nanoscale plates with an {111}α habit plane has been found for the first time to precipitate in the alloy according to a heterogeneous mechanism, namely, along low-angle boundaries, dislocation lines, and at the θ′-phase/Al-matrix interphase
boundary.
