DESCRIPTION:Dr. Jeremy Mason\, Lawrence Livermore National Laboratory\nHis
 torically\, principles guiding the rational design of polycrystalline mate
 rials have focused on structures the scale of a single grain or smaller. 
  For example\, the Hall-Petch relationship is attributed to dislocation pi
 leup within a grain\, without considering the interaction of the grain wit
 h the surroundings.  The opportunity to engineer a microstructure at long
 er length scales depends on the development of suitable language and conce
 pts to describe the statistical features of grain ensembles though.  This
  seminar will discuss two ongoing efforts in that direction.  The first i
 s a quaternion-based approach that simplifies the analysis and visualizati
 on of orientations and crystallographic texture.  The second is a techniq
 ue to completely describe the statistical topology of a grain boundary net
 work and rigorously compare the differences between microstructures.
