Recrystallization of a supersaturated Al-Mn alloy

The response of thin Al-Mn strips to interannealing was investigated. The surface of the sheet samples cold rolled to epsilon < 0.9 is rearranged during annealing at 500 degrees C merely by grain growth. Sheet samples cold rolled to epsilon > 0.9 recrystallize fully at a lower annealing temperature of 450 degrees C. While recrystallization is accelerated with further increase in strain, recovery becomes the predominant mechanism through which the strain energy is released during annealing sheet samples starting at epsilon similar to 1.6.
