Abstract

In this paper, the effects of microstructure on fracture toughness were studied in Al-Cu-Mg alloy, including 2024 and 2124. As the ratio of Cu and Mg was similar in both alloys, the impurity elements in 2024 would lead to the formation of A₁₆(Mn,Fe) and Al₇Cu₂Fe phases, which could affect the tensile strength and fracture toughness of the alloy. With the high Si content in 2024, θ (Mg₂Si) phase formed in matrix would impose negative factor in decreasing the mechanical property.
