Texture evolution during recrystallisation of cold rolled TWIP steel

Journal Article


Abstract


  • A TWinning Induced Plasticity (TWIP) steel was cold rolled to 42% thickness reduction

    followed by isochronal annealing for 300 s between 600-850 °C. Bulk texture evolution during

    recrystallisation was investigated by X-Ray Diffraction. While the development of the α-fibre after

    cold rolling is typical of low stacking fault energy materials, anomalously higher intensities were

    noted for the Goss ({110}<001>) compared to Brass ({110}<112>) orientations. Upon

    recrystallisation, the main rolling texture components were retained and ascribed to nucleation at

    orientations close to those of the deformed matrix followed by annealing twinning which leads to

    crystallographically identical variants. Unlike previous texture investigations on austenitic steels,

    the relatively homogeneous deformation microstructure and uniform distribution of subsequent

    nucleation sites led to the retention of the F ({111}<112>) orientation. Moreover, the firsthand

    observation of the Rotated Copper ({112}<011>) orientation in TWIP steel is attributed to the

    second order twinning of the A ({110}<111>) orientation.
