Symposium SF02-High Entropy Materials

High-entropy materials (HEMs) have become an exciting and vibrant field of materials science as a new generation of materials. The HEM design concept shifts the focus away from the corners of phase diagrams toward their centers, and allows compositions beyond the scope of traditional materials, offering unprecedented properties, challenges, and opportunities for a wide range of structural and functional applications. Although we understand HEMs much better today, there are still significant gaps in our knowledge that hinder the widespread use of HEMs. The goal of this symposium is to share the latest research advances in materials with high configurational entropy, including high-entropy and complex concentrated alloys, high-entropy oxides/ nitrides, high-entropy metallic glasses, etc., and discuss major materials issues for HEMs from property-targeted alloy design to process optimization, from structures to properties, and from the fundamental science to viable industrial applications. This symposium will cover fundamental theory and data-driven material design, fabrication, processing, and microstructure control, such as homogenization, precipitation, nanostructure, and grain-boundary engineering using conventional equipment, combinatorial fabrication, additive manufacturing, etc., phase stability and diffusivity under extreme environment, mechanical behavior under different deformation mechanisms, corrosion, physical, magnetic, electric, thermal, coating, and biomedical behavior, advanced characterization, such as synchrotron, three-dimensional atom probe, and 4-D STEM, computational modeling and simulations, and industrial applications, such as structural, mechanical, biomedical, energy applications. In this symposium, we hope to deepen our understanding of why HEMs attract such intensive interest, as well as highlight some challenging issues awaiting resolution to provide viable paths to widespread application and adoption of HEMs.

Topics will include:

  • Fundamental Theory and Data-driven Design of HEMs
  • Process Development for Tailor-made Synthesis and Microstructure Control
  • Phase Transformation (thermodynamics and kinetics) under Extreme Environments
  • Structural/Mechanical Properties of HEMs, such as fatigue, creep, and fracture behavior
  • Dynamic Mechanical Behavior under Different Deformation Mechanisms
  • Physical, Chemical and Functional Properties of HEMs
  • Intensive Structural Characterization using Cutting-edge Analysis Techniques
  • Theoretical Modeling and Computational Simulations
  • Innovative Industrial Applications, e.g. Structural Parts, Catalysis and Energy Storage Materials
