This project showcases the effects of the homogenization treatments applied to 2724 cast aluminum alloy semi-products, as well as the results regarding the resistance and plasticity improvement of these semi- products. These results have proven the validity of the initial processing hypothesis, which states that certain modifications of the crystalline structure can lead to the improvement of the characteristics mentioned above. A highly resistant 2724 aluminum alloy sample, representing the Al-Cu-Mg system, was used for this experiment. At a structural level, the alloy is made of aluminum based solid α solution grains and a series of binary, ternary or complex intermetallic phases that can either be soluble or insoluble. This type of alloy is mostly used in the machine building or aeronautics industry. The results are according to the microstructural observations, the homogenization heat treatment effect leading to the removal of any chemical heterogeneity (dendritic segregation) and a balanced structure made of polyhedral crystals and a homogeneous dispersion throughout the whole mass of the alloy.
