Recrystallization kinetics and associated textures of Cu-bearing Ti-IF steels

The influence of copper on recrystallization of Ti-stabilized interstitial free steels has been studied. It is shown that the recovery and the recryst allization kinetics are slowed down. Thus the final recrystallization textu re is modified: whereas the gamma-fiber is still present, its intensity is lower. The deformed alpha-fiber contribution is larger than without copper and its magnitude depends on the annealing conditions: it is all the more i ntense as the heating rate is small. These effects are related to the prese nce of copper-based precipitates. The recrystallization textures are discus sed in function of the precipitates evolution.
