Figure 2

The scaled PSDs for γ′ are compared with the prediction of the LSW coarsening theory by Lifshitz and Slyozov18 and Wagner19 (dashed line). The probability density is g(u) and u=R/<R> is the scaled particle radius, where R is the equivalent radius of a γ′ precipitate and <R> is the average equivalent radius of 100 γ′ precipitates. This is shown after ageing at (a) 1,548 K/4 h+1,213 K/0.75 h and subsequently at 1,023 K for (b) 6 h, (c) 24 h, (d) 96 h, (e) 192 h and (f) 384 h.
