The changes observed in the scattering pattern during the initial stages of ageing an Al–20 wt.% Ag alloy at 220°C are reported. Patterns containing both the halo (resulting from G.P. zones) and streaks (resulting from platelets of Ag 2 Al) have been recorded. An analysis of these streaks shows that the platelets are no more than 9 Å thick. This value is much smaller than that previously reported.
