The development of global microstructure characteristics has been compared to the local distribution and extent of Σ3 and Σ3n (1 n 3) grain boundary clusters as a function of thermo-mechanical processing in Type 304 stainless steel. A cold reduction of 5% produced GBE modified microstructures on annealing at 1050°C, containing almost one order of magnitude longer maximum cluster lengths than the corresponding annealing treatments for a reduction of 15%. Differences in the development of the distributions of cluster length scales were observed between the thermo-mechanical treatments. A re-conversion of the longest cluster obtained after GBE processing was observed with long annealing times. The local distribution of Σ3n boundary clusters was assessed, and regions with a low density of clusters are indicative of the onset of GBE conversion of microstructure.

Abstract A creep-deformation, heat treatment impact-fracture technique that can be used to produce grain boundary surfaces is described. The technique is especially useful for exposing grain boundaries of austenitic stainless steels and can also be used with surface-sensitive analytical techniques. Intergranular fracture surfaces of Type 304 stainless steel have been produced using this technique. Auger electron spectroscopy analysis was performed on these fracture surfaces.
