Dynamic restoration and microstructural evolution during hot deformation of a P/M Al6063 alloy

► Restoration mechanisms in a P/M Al6063 alloy were studied. ► Microstrucural changes during hot deformation were analyzed by TEM and EBSD. ► The activation energy of the hot deformation was determined. ► Correlations between Zener-Hollomon parameters and the size of subgrains and recrystallized grains were established. ► DRV prevailingly occurred at high Z values DRX was the dominant mechanism at the low Z values.
