Solution plus ageing leads to the precipitation of finer and more homogeneousγ′ precipitates in comparison to direct ageing. Solution treatment at 1220 °C eliminates the large primaryγ′ phase and replaces them with homogeneous secondaryγ′ precipitates. Coarsening ofγ′ particles according to Ostwald ripening mechanism is confirmed. An increase of the critical resolved shear stress (CRSS) is observed for the under-aged specimens, followed by a maximum of CRSS atγ′ particle size of around 100 nm and a decrease of CRSS for the over-aged specimen. This result agrees well with the highest yield strength and microhardness of the 750 °C × 24 h aged specimens.
