Symposium I: Nanomaterials for Structural Applications
Abstract
Symposium I on Nanomaterials for Structural Applications provided an overview of current multidisciplinary research in this rapidly growing field with the primary focus of reinforcing the relationship between basic science and engineering at the nanoscale level. Thematic sessions covered nanostructured bulk materials, films, coatings, and nanocomposites. These new materials are now being introduced in structural applications, such as wear resistance and plastic-forming, and load-bearing uses. Nanophase or nanocrystalline materials are also being used in electronics, refractory, biological, and catalytic applications. Progress in a wide range of structural applications for nanomaterials crucially depends on the development of new fabrication and processing technologies, along with a fundamental understanding of the relationship between the structure and properties. Among the most important issues discussed are experimental data, and theoretical and computer models concerning deformation mechanisms in nanostructured materials, which, in general, are different from those in conventional coarse-grained materials. The competition between conventional and unusual deformation modes is believed to cause the unique mechanical properties of nanomaterials, serving as a basis for their structural applications. Fabrication of nanomaterials with bimodal (nano- and micrograined) composite structures, that exhibit both very high strength and reasonable ductility, represents a promising strategy in synthesis of nanomaterials with enhanced mechanical characteristics for various applications. High strain rate and low-temperature super plasticity of some nanocrystalline materials are the subjects of growing fundamental research efforts motivated by a range of new applications of these super strong and super plastic materials in net shaping technologies.
