Hot rolling textures of Al-Cu-Li and Al-Zn-Mg-Cu aeronautical alloys: Experiments and simulations to high strains

▶ Systematic hot plane strain compression tests have been made under controlled conditions of temperature and strain to compare texture evolution in Al-Zn-Mg and Al-Li-Cu. ▶ The hot rolling textures in Al-Cu-Li are the same as those of standard Al-Zn-Mg alloys, when deformed under the same conditions. ▶ The stronger textures, particularly the Brass {110}<112> component, of industrially rolled Al-Cu-Li are due to the higher rolling temperatures. ▶ The experimental results are consistent with the model of non-octahedral slip at high temperaturesz.
