N2 - Microstructural changes, such as the density of grain boundary (GB) and dislocation density, due to isochronal annealing in severely plastic-deformed commercial purity aluminium up to 523 K was evaluated using electrical resistivity measurements and scanning transmission electron microscopy. Eventually, the GB density decreases from about 7.2 × 106 to about 2 × 106 m-1, whilst the dislocation density decreases from an initial value of around 1.3 × 1014 m-2 down to around 4 × 1013 m-2.
