Historically, principles guiding the rational design of polycrystalline materials have focused on structures the scale of a single grain or smaller. For example, the Hall-Petch relationship is attributed to dislocation pileup within a grain, without considering the interaction of the grain with the surroundings. The opportunity to engineer a microstructure at longer length scales depends on the development of suitable language and concepts to describe the statistical features of grain ensembles though. This seminar will discuss two ongoing efforts in that direction. The first is a quaternion-based approach that simplifies the analysis and visualization of orientations and crystallographic texture. The second is a technique to completely describe the statistical topology of a grain boundary network and rigorously compare the differences between microstructures.
