Summary

Annealing processes of an ultra fine-grained (UFG) 304 stainless steel with an average grain size of about 0.3 µm were studied at 973 K. The strain-induced UFG structure is essentially stable against recrystallization. The sequential annealing processes are recovery and transient recrystallization, followed by normal grain growth. The annealing behavior is discussed with reference to classical recrystallization.
