The microstructure of homogenized Al–Cu–Li alloy is greatly affected by cooling rates. The air-cooled sample is dominated by high temperature precipitated T (Al₂₀Cu₂Mn₃) phase and β′ (Al₃Zr) phase, accompanied by naturally aged δ′ (Al₃Li) phase. But for the furnace cooled sample, except for the T phase and δ′/β′ phase, the predominant phases are numerous micrometer-scale T₁ (Al₂CuLi) phase and some of θ′ (Al₂Cu) liked phase.
