Evolution of Connectivity Among CSL Boundaries During Hot Plate Rolling of 316H Stainless Steel and the Effect on Intergranular Corrosion Resistance
Effects of the topological grain boundary network in hot rolled plates of 316H on intergranular corrosion (IGC) propagation were studied, which demonstrated that the connectivity among low-Σ coincidence site lattice (CSL) boundaries, instead of the CSL fraction, played the dominant role in arresting the IGC propagation. It was worked out that original dynamic recrystallized structures with homogeneous CSL boundaries and larger grain size were the efficient way to improving the CSL connectivity, which can be realized by optimizing the processing parameters during hot plate rolling.
