Abstract

This study aims to improve the intergranular corrosion resistance of 316 austenitic stainless steel by grain boundary engineering. The significantly high frequency of coincidence site lattice boundaries and fully disrupted random boundary network were obtained by slight pre-strain and subsequent annealing for 72 h. The corrosion rate of grain boundary engineered 316 stainless steel during ferric sulfate-sulfuric acid test was reduced to one-fourth of that of base material. It was suggested that the optimized grain boundary character distribution effectively suppressed the propagation of intergranular corrosion into the grain boundary engineered 316 austenitic stainless steel.
