Abstract
Modification in grain boundary character distribution has been known to improve the functional and mechanical properties of low stacking fault energy, face centered cubic materials. In this work, thermomechanical processing has been employed on nickel alloy using iterative and single-step, non-iterative routes to gain an insight into the role of processing path on the generation of low-σ coincidence site lattice (CSL) boundaries. A low amount of strain (~4 %) has been used in iterative processing in order to obtain CSL boundaries with less deviation. Evolution of σ1 and σ3 boundaries showed different trends during iterative and non-iterative processing. Also, iterative processing resulted in low-σ CSL fraction (σ ≤ 29) as high as 0.9 consisting of significant fraction from both σ1 and σ3 boundaries. Non-iterative processing yielded low-σ CSL fraction of 0.73 but with significant contribution only from σ3 boundaries.
