Study on Characteristics of Heat Treatment of The AA2024 Aluminum Alloys

This study examined the behavior of AA2024 aluminum alloys, which received different heat treatments, i.e., homogenization, quenching, artificial aging, and recrystallization. The homogenization temperature is set at 495 °C for 5 hours followed by slow cooling in furnace. Then a quenching treatment was done with cold water. Artificially aged alloys were heated to hours, rapid water cooling, then heating 140 2 recrystallization also studied solution 310 3 In this study, we used an optical microscope scanning electron analyze microstructures samples. X-ray fluorescence analysis determine proportion each element on surface alloy. Phase structural analyses performed diffraction while mass loss calculated after 60 exposure all samples climate chamber. Our work revealed that rate could decrease alloy due emergence additional phases dispersoids. result showed fraction changed aggressive environment, Al2Cu Al2CuMg disappeared as from XRD data.
