Figure 2 Relationship between the Zn contrast (precipitate composition - matrix composition) and the precipitate volume fraction for the T' state and the T state (a and b, respectively). Slightly inclined curves correspond to equation (2) with different hypotheses on Al composition in the precipitates. Steep curves correspond to equation (3) for different hypotheses in the confidence range for the overall and matrix Zn contents. TEM and TAP (filled circles) evaluations are also reported (M. Dumont et al., 2005; courtesy Elsevier).
