Microstructural characterization by electron backscatter diffraction of a hot worked Al-Cu-Mg alloy

▶ The most favourable conditions for hot workability have been determined. ▶ EBSD was employed to characterize the obtained microtexture and microstructure. ▶ The Al 2024 alloy torsion tested at 408 °C and 2.1 s−1 showed maximum ductility. ▶ Solid solution and fine precipitates favour a fine microstructure at 408 °C. ▶ The increase in test temperature to 467 °C produces a sharp decrease in ductility.
