Abstract:
The proportion of low Σ coincidence site lattice (CSL) grain boundaries was enhanced by grain boundary engineering (GBE) in Alloy 690. The grain boundary network was characterized by electron backscatter diffraction (EBSD) technique. Formation of large size grain cluster is the feature of the grain boundary network after GBE treatment. All of the grains in this kind of cluster
