Abstract

The influence of cold roll reduction history on grain boundary network development in an austenitic stainless steel has been investigated. A dominant effect of the final thermomechanical process cycles on grain boundary character development was observed. The application of low-strain processing cycles with 5% cold reduction was found to increase the fraction of Σ3 and Σ3-related variants on solution annealing. Two-step processing treatments with final reductions between 15% and 82% showed no significant differences to their single-step processed equivalents. © 2008 Acta Materialia Inc.
