Further information
This sample was annealed and 50% cold rolled, with subsequent annealing for 30 minutes at 600 °C. This has caused partial recrystallisation to occur creating new dislocation-free grains with some annealing twins. The temperature is too low for significant grain growth preventing complete recrystallisation.
