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 ε < 0.9 is rearranged during annealing at 500 °C merely by grain growth. Sheet samples cold rolled to ε > 0.9 recrystallize fully at a lower annealing temperature of 450 °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 ε ∼ 1.6.
