Multimodal size distribution of phase was obtained in a slow-cooling experiment following supersolvus solution treatment (1191 degrees C). The morphology of the secondary particles exhibited splitting and protrusion instabilities. In the subsequent aging process (815 degrees C), reverse coarsening was observed, i.e., the average precipitate size decreased with increasing aging time. Reverse coarsening slows the coarsening rate of the precipitates, increases the hardness of the alloy, and greatly improves the morphological stability of the phase.
