Recovering Grain Boundary Inclination Parameters Through Oblique Double-Sectioning

A method for the retrieval of grain boundary inclination parameters of the grain boundary character distribution by oblique double-sectioning is proposed. The method, which is similar to the recovery of the orientation distributions from sets of incomplete pole-figures, is described along with a framework for implementation. The method directly measures grain boundary inclinations in a manner similar to serial sectioning while statistically sampling the microstructure comparably to stereological methods. Computer simulations of the method were used to confirm the mathematical framework. Additional simulations, where the grain boundary normal distributions were recovered by both oblique double-sectioning and stereological methods, showed that results recovered by 3 orthogonal double-sections from oblique double-sectioning proved to be just as accurate as the 25 section-cuts required for stereology in resolving the finer details in the recovered distribution.
