||This symposium gives an avenue for scientists, researchers, and engineering to present their recent applied and theoretical research results on a number of topics regarding the mechanical behavior of high-entropy alloys (HEAs) or multi-principal element alloys (MPEAs).
BACKGROUND AND RATIONALE: HEAs and MPEAs contain five or more primary elements and can consist of a combination of body-center-cubic (BCC), face-centered-cubic (FCC), and hexagonal-close-packed (HCP) solid-solution phases. These alloys have also been found to possess many desirable properties, such as exceptional corrosion and irradiation resistance, high strength and ductility, and high fatigue/wear resistance. These desirable characteristics, therefore, make HEAs/MPEAs potentially viable candidates for several industries including those in the energy, biomedical, automotive, and aerospace sectors.
Topics of interest include, but are not limited to:
(1) Innovative methods to study plastic serrated flow, hardness, creep, fatigue, and wear
(2) Multiscale approaches to investigate fatigue and fracture in structural materials
(3) Advanced in situ and high throughput characterization methods, including neutron scattering, transmission electron microscopy, X-ray diffraction, electron backscatter diffraction, and three-dimensional (3D) atom probe tomography
(4) Innovative computational modeling and simulation techniques, such as phase-field modeling, molecular dynamics, Monte Carlo, CALculation of PHAse Diagrams modeling, finite-element methods, density functional theory machine learning methods, and integrated computational materials engineering (ICME)
(5) Microstructural control, such as hierarchical structure, which modifies the physical and mechanical behavior
(6) Applications of mechanical properties in the nuclear, aerospace, biomedical, and other industries
