Commercial purity Al AA1200 cold rolled to a true strain 2 was annealed at 270°C for a series of times. The microstructural parameters V V, the volume fraction recrystallized, S V, the interfacial area density separating recrystallised grains from deformed matrix and , the mean chord length of recrystallising grains, were measured stereologically using the EBSD technique. The recrystallisation kinetics were studied and the growth rates calculated by the extended Cahn–Hagel equation. It was found that the recrystallisation kinetics exhibited a two stage behaviour: an early stage characterised by decreasing growth rates, and a later stage with approximate constant growth rates. On average cube grains grow about two times faster than other grains and the growth rates of the three rolling texture components, brass, copper and S, are almost the same.
