Abstract
The effects of magnetic field direction on γ‐fiber texture evolution in as‐annealed interstitial‐free (IF) steel sheet were investigated by means of X‐ray diffraction ODF analysis. Specimens cut from cold‐rolled IF steel sheets were placed at the center of a 12‐T magnetic field, tilted by different angles to the magnetic field direction respectively, and annealed at 750 °C for 30 min. The results show that altering the specimen orientation to the magnetic field direction during annealing does not change the final annealing textures. The average intensity of the γ‐fiber texture of specimens annealed under the magnetic field is higher compared to conventionally annealed specimens. The intensity of the main γ‐fiber texture components presents a similar periodic variation with respect to the specimen orientation to the magnetic field, i.e., it is weakened as the tilt angle increases from 0°, and subsequently strengthened to a maximum value at 45°, and then weakened again as the tilt angle continues to increase. When the magnetic field is applied in the direction perpendicular to the specimen's rolling plane, the intensity of the main γ‐fiber texture components of specimens annealed in the magnetic field is close to that of the specimen annealed without field. This phenomenon might be attributed to the demagnetic effect.
