Symposium MS04—High-Entropy Alloys and Other Novel High-Temperature Structural Alloys

With the rapid development and broad fields of applications, high-entropy alloys and other novel high-temperature structural alloys, such as refractory alloys, Co-based superalloys, ordered intermetallics, have become an inspiring and intriguing research area in materials science recently. To develop these novel alloys with improved mechanical behavior, stability, formability, and other advanced properties, it requires innovative synthesis and processing strategies based on the understanding of the fundamental transformation and deformation mechanisms. Currently, this objective becomes more achievable because of the development of computational methods, data science techniques, characterization tools, and synthesis/processing strategies. For this reason, this symposium will broadly cover the computational and experimental studies of current and emerging high-entropy alloys (including high-entropy superalloys, high-entropy oxides/ nitrides, high-entropy metallic glasses, high-entropy nanomaterials, high-entropy alloy composites, and high-entropy oxides) and other novel elevated-temperature structural alloys.

This first part of the symposium will focus on thermodynamic stability, synthesis, and processing methods. It will cover the phase and surface stability for various types of high-entropy alloys and other high-temperature structural alloys, especially those under extreme conditions (high temperature, corrosion, irradiation, etc.). It will also include different synthesis and processing methods via cast, wrought, powder, additive-manufacturing, or coating routes. The second part of the symposium will focus on their performances and the corresponding mechanisms. It will cover their mechanical-deformation behavior, and the corresponding mechanisms from atomistic to continuum scales, including the defects (dislocations, twin/grain boundaries, etc.) structures/evolution and defect-defect interactions, under different temperatures and environmental conditions. It will also cover the applications beyond structural purposes, such as biomaterials and their related biocompatibility.

From the methodology aspect, the symposium will encourage the topics on the emergence of novel design/simulations, characterization, and synthesis/processing techniques, such as materials design based on machine learning and artificial intelligence, the application of in-situ testing and characterization techniques under different environmental conditions, and integrated computational materials engineering (ICME). This symposium will hence offer a platform for networking, collaboration, and the exchange of information for the community.

Topics will include:

  • High-entropy alloys/materials, refractory alloys, Co-based superalloys, and ordered intermetallics, light-weight materials
  • Materials design
  • Processing development
  • High-resolution, in-situ and microstructural characterizations
  • Mechanical, physical, chemical, and bio-medical properties
