Notes:
The variations during isochronal annealing of cold-rolled commercial pure Al (1050) andAl-Mn (3004) has been investigated between room temperature (RT) and 823 K. The annealingstages have been identified as recovery, partial recrystallization, complete recrystallization and graingrowth using positron annihilation lifetime (PAL) spectroscopy, Doppler broadening of annihilationradiation (DBAR) spectroscopy and Vickers microhardness (Hv) measurements. The retardation ofcomplete recovery in Al-Mn alloys is due to the presence of vacancy-Mn complexes. A positivecorrelation has been found between positron annihilation parameters (τav & Snor) and mechanicalproperties (Hv) for the two alloys under investigation
