Correlations Between the Crystallographic Texture and Grain Boundary Character in Polycrystalline Materials
R E. Garcia, Mark D. Vaudin
A method is presented to determine the misorientation probability distribution function in polycrystalline materials based on a known, analytical or numerical, representation of the associated orientation probability distribution function, i.e., texture. The proposed formulation incorporates the local grain to grain orientation correlations by combining local or macroscopic statistical information, and finds a natural interpretation through the well-known stereographic projection (pole-figure) representation. The proposed formulation distinguishes between anti-parallel crystallographic orientations, as well as cone-angle and polar angle misorientations. For fiber-textured samples, it is quantitatively shown that highly oriented samples are equivalent to polycrystals with a high density of low angle misorientations, while completely random (untextured) materials are equivalent to microstructures with a high probability of large angle misorientations .
