Effect of large strains on grain boundary character distribution in AISI 304L austenitic stainless steel

Austenitic stainless steel of 304L type was thermo-mechanically processed to enhance special low CSL boundaries. Rolling reductions of above 60% of thickness was employed prior to annealing. It was observed that during recovery and recrystallization, twinning induced CSL boundary of Σ3 type. However, 80% of thickness reduction during grain growth regime, retarded Σ3 type grain boundary formation.
