Abstract


This paper presents the thermal, microstructural and mechanical changes of a AA3005 aluminium alloy during the different stages of manufacturing process, from continuous cast billet (20 mm thick) , along the different plastic deformation stages, till the last lamination (1.5 mm thick). The optical and scanning electron microscopy study of the different sheets obtained both in the cast and after each lamination, as well as the differential scanning calorimetry study has allowed us to identify the different thermal states of the sheets. The information provided by this technique was completed by transmision electron microscopy analysis. The interaction between the different processes occurred in the material during its manufacturing determines its final microstructural state, its mechanical properties, evaluated with hardness and tensile tests, as well as its behaviour for later forming processes. The recrystallization and precipitation phenomena increase mechanical properties during the manufacturing process.
