Fig.5. TEM images and selected area electrom diffraction SAED patterns of the precipitates in the grain under ageing states of T6 (a), T73 (b), 1/215/L (c), 3/225/L (d), RRA (e) (The SAED patterns are shown at the upper right corners. The insets at the lower left corner in Figs.5a, b and e are the schematics of diffraction patterns along [001]Al, and these in Figs.5c and d are the schematics of diffraction patterns along <112>Al)
