Abstract: The effect of temperature on recrystallization texture and microstructure of 3004 aluminium alloy has been investigated by means of orientation distribution function (ODF) and transmission electron microscope (TEM). The results showed that the orientation intensity of recrystallization cube texture |001| (100) is strong in annealed samples and become stronger along with increasing annealing temperature of which the intensity grades are f(g)∼8 and f(g)∼12 after annealing for 120 min at 350°C and 450°C respectively. But, the intensities of recrystallization texture R/S{124}<211>, S{123} <634> and C{112} <111> are weak; TEM images showed that the recovery process of the sample comes to the end after annealing at 250°C for 120 min. If annealed at over 300°C, the recrystallized grains grow increasingly and the 2nd-phase particles are precipitated further to disperse on the subboundaries in grains with dislocations surrounding them along with the increasing annealing temperature. Moreover, the 2nd-phase particles play the role of fostering the nucleation in recrystallization process.
