On the influence of dispersoids on the particle stimulated nucleation of recrystallization
Recrystallization of Al alloys is controlled by precipitates. Whereas large particles are generally assumed to promote recrystallization by particle stimulated nucleation, finely dispersed precipitates, either already present in the as-deformed state or precipitating during the recrystallization anneal, are known to strongly retard the progress of recrystallization. It was the aim of this study to elucidate these concurring effects of large particles, and small dispersoids as well as of a supersaturation of solutes on recrystallization in a ternary Al-Fe-Si model alloy. Samples were prepared with different pre-annealing treatments to produce different states of precipitation and supersaturation. Evolution of the microstructure and of the crystallographic texture was followed during cold rolling and recrystallization. Conclusions were drawn on the efficiency of recrystallization nucleation at the various nucleation sites and, especially, on the influence of dispersoids on recrystallization.
