Conclusions

  1. 1.

    Cold rolling of alloy specimens leads to formation of a two-component texture which with deformation at the level of about 30% approaches the baseline. This creates a region of critical reduction (27–40%) were material failure is possible. This region may be passed by repeated rolling with small (approximately 2.5%) reductions per pass. With further deformation (50% or more) a texture of the deviation type forms which makes it possible to achieve (80–90%) reductions.

  2. 2.

    In order to obtain good structural, textural, and mechanical characteristics it is recommended that vacuum annealing in the furance or high-speed heating above the phase recrystallization temperature with cooling in air is carried out after cold rolling. Subsequent short-term annealing in the furnace at 800°C with air cooling was a favorable stabilizing effect on alloy structure.
