Abstract
This article presents a systematic study to highlight micromechanisms associated with the grain interface character distribution of SS304HCu. The low-energy coincidence-site-lattice (CSL) boundary fraction is found to be increased (33 to 62 pct) with an increase in annealing temperature from 1073 K to 1323 K after 50 pct cold rolling. Furthermore, an increase in annealing temperature has shown reduction/saturation for CSL (~ 58 pct) due to diffusion-assisted grain boundary migration. Associated effective grain boundary energy has been calculated to rationalize the energy minimization process during annealing.
