The microstructures and mechanical properties of a hot extruded Al–Zn–Mg–Cu alloy pipe with variable cross-section areinvestigated by transmission electron microscopy, electron backscattering diffraction, hardness testing and finite elementmethod. The results suggest that the variable temperature distribution at different positions along the extrusion directionafter hot extrusion attribute to the changes in hot deformation degrees. The extruded profile at billet temperature of 410 °Cand a ram speed of 1.5 mm/s shows a gradual increase in temperature from 416 to 467 °C at strains from 3.7 to 8.6 alongthe extrusion direction. The dynamic recovery (DRV) and partial dynamic recrystallization (DRX) are observed in the hotextruded profile, and high-angle grain boundaries fraction exponentially rises along the extrusion direction. The hardnessat different positions of the hot extruded profile shows a nearly exponential decline along the extrusion direction, mainlyascribes to the decrease of the dislocation density that caused by the dynamic softening.
