boundary plane distributions in a cold-rolled and annealed ferritic stainless steel were investigated by means of EBSD techniques. The results show that, following cold rolling with the thickness... distributions are observed. The free energy reduction of the system is most likely attributed to the selective growth.Key words:grain texture; grain boundary plane; EBSD; ferritic stainless steel......
