Study of hot deformation of an Al-Cu-Mg alloy using processing maps and microstructural characterization

► The hot deformation behaviour of the Al 2024 alloy was analyzed by torsion testing, constitutive equations and processing maps. ► EBSD was employed to characterize the microstructure and its correlation with processing maps. ► A forming temperature range of 360-410 °C and strain rates of 2.1-4.5 s−1 is recommended. ► Extended dynamic recovery (DRV) under the most favourable conditions leads to uniform and fine grain size. ► The behaviour of precipitates at processing temperature determines the mechanical properties.
