Abstract Scope |
Over the past few decades, materials scientists have increasingly come to the realization that the distribution and connectivity of different grain boundary (GB) types contribute to the mechanical and functional properties of polycrystalline materials. Despite the role of GB structure in transport and failure mechanisms having been investigated for more than half a century, few robust GB crystallography-property relationships are yet known; this is at least partly due to the inherent complexity associated with the five-dimensional configuration space in which they reside. In this talk, we will introduce a Bayesian optimization framework for constructing GB crystallography-property relationships by sampling the topologically complex (arising due to the bi-crystallographic symmetries) grain boundary manifold in an efficient manner. |
