Effects of magnetic field strength on microstructure and texture evolution in cold-rolled interstitial-free steel by magnetic field annealing

Effects of magnetic field strength on the evolution of recrystallization microstructure and recrystallization texture in cold-rolled interstitial-free steel were investigated after annealing at 660°C in a magnetic field up to 12 T. Magnetic annealing was found to retard recrystallization and induce recrystallized grains elongated along the magnetic field direction. An interesting phenomenon is that the magnetic field shows the strongest effect at 1 T.
