TopicS: Structural Materials

Metallic materials are utilized in widespread areas of our daily life and nearly all industrial sectors. Recent advancements in technological processing and advanced materials characterization techniques speed up the exploration of material structures down to the nanometer scale. Nanostructured metallic materials are often referred as bulk metallic materials with nano-crystalline structures and the engineering alloys strengthened by nano-sized precipitates. This group of materials has attracted growing scientific interest because of many fascinating and promising materials properties compared with conventional coarse-grained materials with the same chemical compositions. The extraordinary properties of nanostructured metallic materials boost novel applications in automotive, aerospace, and energy sectors.

This symposium focuses on all aspects of the recent development of ultrafine-grained and nano-structured metallic materials, advances in novel characterization and simulation methods for nanostructures and properties. This symposium in particular welcomes the contributions on the aspects of science and technology for ultrafine-grained (UFG) and nano-crystalline (NC) materials that typically show grain sizes below 1 micron and 100 nm respectively. It provides a forum to present and discuss latest research on fundamental aspects regarding UFG and NC microstructures, strength, ductility, work-hardening, fatigue, thermal stability, corrosion, creep and fracture as well as on processing such materials via conventional and emerging processing technologies.

Topics of special interest include but are not limited to:

  • Mechanical and physical properties as well as controlling mechanisms of novel nanostructured metallic materials, e.g. nanostructured high-entropy alloys, advanced high-strength steels, metallic glass nanocomposites, etc.
  • Advanced characterization methods for in-depth nanostructure investigation, e.g. high-resolution transmission electron microscopy (HRTEM), atom probe tomography (APT), high-energy X-ray diffraction (HEXRD), small-angle X-ray/neutron scattering (SAXS, SANS), etc.
  • Advances in the processing of nanostructured materials, e.g. severe plastic deformation (SPD), accumulative rolling-bond, solid-reaction, etc.
  • Computational and analytical modeling of nanostructures and their properties, e.g. ab initio calculations, phase-field modeling, crystal plasticity modeling, etc.
  • Applications of nanostructured metallic materials.
