||Future energy technologies demand novel materials that tolerate extremes in temperature, strain, strain rate, and radiation to an extent that far exceeds the limits of even the most advanced materials to date. To meet these needs, promising new material candidates are nanostructured multi-phase/multi-interface materials. Interfaces, such as grain boundaries, phase boundaries, and surfaces are important in materials of any microstructural size scale, whether the microstructure is coarse grained, ultra-fine grained or nanograined. In nanostructured materials, however, they dominate material response and can lead to extraordinary and unusual properties that far exceed those of their coarse-grained counterparts.
To accelerate the development and acceptance of new concepts and methodologies in understanding interface physics in monophase and multiphase materials and characterizing and fabricating materials with designed interfaces, this symposium will focus on recent achievements in materials development in terms of the understanding of deformation mechanisms, the exploitation of advanced properties (e.g. shock or radiation tolerance), the testing technologies for characterization of small volumes of material, and the 3-D tomographic analysis of defects. Abstracts on recent developments in mechanical testing techniques (e.g., in situ straining in TEM, micropillar testing, etc) and in high-fidelity modeling techniques (e.g., ab initio, molecular dynamics, etc) are also solicited.
The subject areas of the symposium include, but are not limited to:
Mechanical behavior and synthesis of low dimensional materials (e.g., thin films, nanowires, nanotubes, and nanoparticles)
Characterization and modeling of monophase grain boundary and twin boundary effects on mechanical behavior
Phase Boundaries and Multiphase composites, such as metallic glass/ nanocrystalline composites, layered nanocomposites, nanoparticle/matrix composites and nanoporous materials
Advanced materials development such as nanocrystalline materials (metals and ceramics)
Atomistic scale modeling of defects-interfaces interaction, deformation mechanisms and interface interaction with radiation-induced defects
Micro, Meso, and Macro-scales modeling of deformation processes and phenomena as they relate to interface physics
In situ testing methodologies for investigating the mechanical or ion irradiation behavior of small volumes of material
Microscale mechanical testing
3-D tomographic analysis of defects
