Abstract

An extruded Al–Si–Mg alloy was deformed by torsion at 400 °C during in-situ high energy synchrotron radiation diffraction. This technique is used to prove, by analysing texture changes and the coherently scattering domain size evolution, that dynamic recovery followed by continuous dynamic recrystallization are the main restoration mechanisms. Moreover, the dislocation density types corresponding to each stage of deformation are discussed and the recrystallization grade is calculated.
