The properties of grain boundaries (GBs) primarily depend on their atomistic structure. Traditionally, Structural Unit Models (SUMs) have been utilized to characterize the atomic makeup of GBs. However, these models are applicable only for a limited set of GBs (twist and tilt configurations of low-Σ GBs) and a general framework for quantifying the structure of general GBs does not exist. In this talk, we will extend the 3D polyhedral unit model proposed by Ashby et al. to describe the structure of general metallic GBs. We have implemented a point-pattern matching algorithm to automate the identification of polyhedral units. A general framework for quantifying the structure of GBs, in the full crystallographic five-dimensional phase space, using three-dimensional structural units will be presented.
