Recrystallization of copper

This video is provided for educational purposes by Professor John Humphreys, Manchester University. A sample of high purity copper was cold rolled to a reduction of 50%, metallographically prepared, and annealed at 300 C in a Field Emission Gun Camscan SEM. Backscattered electron images were acquired at intervals of 30 s. The deformed material shows contrast variations due to changes of crystallographic orientation within the grains. Note the formation of annealing twins during recrystallization. (Ian Br
