Summary

Copper-rich 7000 series aluminum alloys are widely used for thick plate aerospace applications. A major concern for such applications is the quench sensitivity of the alloy, since quench-induced intergranular precipitation partly controls important mechanical properties such as toughness. The purpose of this work is to study the quench sensitivity of two alloys, AA7040 and AA7050, by a detailed quantitative study of their microstructure. Notably, a novel technique of Small-Angle X-ray Scattering is used to determine quantitatively the relative volume fractions of intergranular and intragranular precipitation.
