| Abstract Scope |
Grain boundary engineering (GBE) has been applied to many FCC materials, resulting in vast improvements in a number of boundary-controlled properties, including diffusional creep and stress corrosion cracking. In this work, the microstructure of an austenitic stainless steel (316L) was reconstructed in three dimensions to characterize the 3D networks of grain boundaries, including both general high-angle boundaries and special coincident site lattice (CSL) boundaries. The microstructure is characterized using serial sectioning and EBSD, and the connectivity of the grain boundary networks is measured, for both an as-received specimen, and one which has been subjected to Grain Boundary Engineering to increase the population of special CSL boundaries. The 3D connectivity of the boundary networks is quantified and correlated to simulated materials response. |
