Intergranular corrosion is the main type of Al-Cu-Mg aluminum alloys, which seriously reduce lifetime aircraft structural parts. In this paper, microstructure and intergranular behavior 2024 alloy with varying Cu Mg content were studied by using a scanning electron microscope (SEM), transmission (TEM), three-dimensional atom probe (3DAP). The results show that nano-scale θ (Al2Cu) S (Al2CuMg) p...

The precipitation and evolution of microstructure in a spray-cast Al-7034 alloy and a commercial wrought Al-2024 alloy were studied after equal-channel angular pressing (ECAP) using transmission electron microscopy and differential scanning calorimetry (DSC). Microstructural examination showed the grain sizes of both alloys were reduced to the range of ~0.3–0.5 μm through ECAP. The DSC analysis...
