Symposium CM02—Structure–Property Relations in Non-Crystalline Materials
This symposium will address the fundamental questions of how to characterize the structure of non-crystalline materials and how to correlate structural signatures to material properties. Non-crystalline materials include glass-forming liquids and supercooled liquids, glasses, and amorphous solids (which, unlike glasses, do not exhibit a glass transition). Non-crystalline materials share the common feature that they do not possess long-range translational order. Instead, the properties of these materials are sensitive to short- to medium-range ordering. Further structural complexity can arise from anisotropy, heterogeneity, and hierarchical packing. Due to structural commonalities among a broad range of non-crystalline materials and transferable experimental/numerical techniques for studying them, this symposium will cover glasses and amorphous solids of all compositions (metals, network formers, polymers) and processing histories (vitrified through the glass transition, deposited, deformation- or radiation-induced). Relations of structure to all materials properties including optical, electrical, transport, and mechanical will be addressed.
