摘要：

The phenomenon of continuous recrystallization has been investigated in a heavily cold rolled commercial Al-Fe-Si alloy (AA8079) containing a distribution of both large and small FeAl3 second-phase particles. Transmission electron microscopy revealed that at Bower temperatures the small particles restricted growth by pinning boundaries and at higher temperatures the particles coarsened in size allowing homogeneous subgrain growth to take place. The large particles did not act as preferential sites for nucleation and critical particle sizes calculated for particle-stimulated nucleation are given. It was concluded that continuous recrystallization in the present investigation is a combination of two processes; subgrain growth controlled by particle coarsening and grain growth commencing from a structure comprising predominantly high-angle boundaries.
