Abstract
IGC (Inter-granular corrosion), in a single phase materials, is expected to depend on (a) Chemistry, (b) Grain size and (c) GBCD( Grain boundary character distr-ibution). In the present study, 316L austenitic stainless steel was deformed to different extent by unidirectional and by cross rolling. Subsequent solution: ing , i.e. a combination of primary recrystallization and grain growth, did not bring any noticeable difference in bulk texture. The GBCD, especially the 23 twin boundaries, were, however, significantly different. A difference of more than five times in low CSL (coincident site lattice) boun-daries were obtained. An effort was made to relate the effect of GBCD on corrosion - by DL- EPR (Double loop electrochemical potentiokinetic reactivation).
