Impact of homogenization on recrystallization of a supersaturated Al–Mn alloy

Impact of homogenization on the response of thin Al–Mn strips to interannealing was investigated. A homogenization anneal at the start of processing relaxes the supersaturation of the thin Al–Mn strip and avoids the precipitation–recrystallization interaction. The homogenized samples enjoy, in addition to an already decomposed matrix, a dispersion of coarse intermetallic particles resulting in a faster recrystallization. Reversion of the fine precipitates during cold-rolling and their reprecipitation during a subsequent annealing treatment displaces recrystallization to higher temperatures.
