Abstract
The influence of copper on recrystallization of Ti-stabilized interstitial free steels has been studied. It is shown that the recovery and the recrystallization kinetics are slowed down. Thus the final recrystallization texture is modified : whereas the γ-fiber is still present, its intensity is lower. The deformed α-fiber contribution is larger than without copper and its magnitude depends on the annealing conditions : it is all the more intense as the heating rate is small. These effects are related to the presence of copper-based precipitates. The recrystallization textures are discussed in function of the precipitates evolution.
