SUMMARY:

The study presented an analysis of the behavior and optimization of the AA 3003F aluminum alloy in industrial processes, with a focus on hydroforming and the effects of annealing heat treatment. Initially, an experimental study of the hydroforming process of metal sheets was carried out, highlighting advantages such as weight reduction, material savings, increased mechanical strength, and sustainability. The objective was to create a graphical diagram relating the applied pressure to the working force during forming, in order to predict the material behavior and optimize designs. The AA 3003F alloy with a thickness of 0.4 mm and free die was used to form a hemispherical shape. The samples were subjected to progressive pressures (5 to 20 kgf/cm²) and analyzed by optical microscopy, allowing the identification of parameters and defects, resulting in the hydroforming diagram of the alloy. Subsequently, the analysis deepened into the influence of annealing heat treatment on the mechanical properties of the same alloy. The samples were treated at three temperatures (250 °C, 325 °C, and 450 °C) and then formed until failure. Tensile tests, hardness tests, roughness measurements, and microstructural analysis were performed. The results showed significant improvements: up to 14% increase in tensile strength, 60% increase in forming height (mainly at 250 °C), and adequate roughness for industrial application. Metallographic analysis confirmed work hardening in critical areas, with no relevant structural changes. Overall, the studies demonstrated that the combination of hydroforming and annealing heat treatment enhanced the performance of the AA 3003F alloy, making it viable for industrial applications that require strength, lightness, and good formability.
