The evolution of magnetic inductive parameters during the annealing of a cold rolled low carbon steel is examined in order to analyze whether these hysteresis parameters can be useful to nondestructively characterize recovery and recrystallization processes. Unlike the induction values measured at 2500 A/m (B25) , the remanent induction (Br) values are useful to characterize the decrease in the dislocation density during recovery. As a consequence of recrystallization a weakening of alpha fiber texture and an enhancement of gamma fiber texture components take place. The effect of these textural changes on the magnetic magnetocrystalline energy is analyzed and the observed magnetic response is discussed in terms of this variation. Although Br and B25 can be used to monitor recrystallization in the studied steel, B25 values are more sensitive due to the significant effect that textural changes during recrystallization have at high induction values. |
