“…Similar observation was made during the cold rolling of the material used in the present work, which has been discussed in an earlier report. 14 In the present case also, there was a considerable population of shear band-like features in the cold-rolled microstructure, and it is quite likely that the Goss {110}˂001˃ orientations in the shear bands gave rise to the relatively stronger Bs/Goss {110}˂115˃ type texture at the early stage of recovery, which finally weakened with further progress of recovery. The present study reveals an important fact that the deformation texture of the 80% cold-rolled material does not simply undergo a continuous weakening.…”

“…The textural changes during cold rolling and recrystallisation of this steel have already been reported elsewhere. 14,15 The recrystallisation study revealed that there was an unusually strong Bs/Goss texture formed at the recovery stage, 15 which completely disappeared at the later stage, with the progress of recrystallisation. Therefore, the present work specifically focuses upon the textural changes during the recovery of this high manganese austenitic steel.…”

A heavily cold-rolled (80%) high manganese austenitic steel was subjected to isochronal and isothermal heat treatments, in order to study the texture development during the recovery stage. Progress of recovery was negligible after annealing at 500°C for 60 min, but annealing for 60 min at 800°C led to complete recrystallisation, and appearance of the final texture was very similar to that of a copper type deformation texture. Isothermal heat treatments at 600°C revealed that at the very early stage of recovery, there was a weakening of brass type deformation texture, but it was followed by a sharpening of Bs component. At the same time, there was a shift of peak intensity towards Bs/Goss location. After this stage of intermediate sharpening, the texture sharpness experienced a continuous weakening with further progress of recovery.
