A study of precipitation and recrystallization behaviour of aluminium alloy AA1235

The recrystallization behaviour of 92% cold rolled commercial pure aluminium has been
studied. Annealing was done at different conditions to evaluate the effect of recrystallization
temperature and time on the microstructure and texture of the alloy along with a study of
subsequent precipitation. Variation of orientation between grains has been studied by the
orientation imaging microscopy (OIM). During precipitation, cube component {001}<100> has
dropped and rolling texture component {112} < ¯1 ¯ 11 > has increased comparatively.
Recrystallization texture is the combination of cube, rolling and random texture. However,
during grain growth strong cube grains have formed. A significant number of dislocations are
present during grain growth owing to the pinning effect of Al3Fe particles.
