Abstract Scope |
Grain boundary networks (GBNs) create a highly complex structure in crystalline materials that significantly influence their macroscopic properties. One recent method used to characterize these complex networks is Spectral Graph Theory. In this approach, GBNs are represented by a matrix of nodes and weighted edges, the eigenvalues and eigenvectors of which give a unique description of the GBN configuration. Using a single eigenvalue and eigenvector we identified the dominant microstructural features that govern macroscopic transport properties in polycrystals. In this talk we show how higher order terms provide additional information that can be used to identify and rank the contributions of a variety of microstructural features and their contributions to the macroscopic material properties. |
