ADVERTISEMENTS The three thermally active and overlapping stages during annealing are 1. Recovery 2. Recrystallisation 3. Grain Growth. The first two stages of annealing are caused by the stored cold- worked energy. Grain growth, the third stage of annealing, occurs if annealing is continued after recrystallisation has completed. In this stage, the recrystallised grains grow
