Scope This symposium provides a platform for researchers, scientists, and engineers to present their newest theoretical and applied research findings on multiple topics pertaining to the mechanical behavior of multi-principal element alloys (MPEAs) or high-entropy alloys (HEAs).

BACKGROUND AND RATIONALE: MPEAs and HEAs consist of five or more primary elements and are composed of body-center-cubic (BCC), face-centered-cubic (FCC), and hexagonal-close-packed (HCP) solid-solution phases. These alloys can exhibit desirable properties including high strength and ductility, excellent corrosion and irradiation resistance, and high fatigue/wear resistance. Such desirable characteristics make MPEAs/HEAs potential candidates for several applications including those in the aerospace, automotive, biomedical, and energy industries.

Topics of interest include, but are not limited to:
(1) Multiscale approaches to investigate fatigue and fracture in structural materials
(2) Advanced in situ and high throughput characterization methods, including transmission electron microscopy, neutron scattering, X-ray diffraction, three-dimensional (3D) atom probe tomography, and electron backscatter diffraction
(3) Innovative techniques to examine creep, hardness, fatigue, wear, and serrated plastic flow
(4) State-of-the-art simulation and computational modeling techniques, such as phase-field modeling, molecular dynamics, CALculation of PHAse Diagrams modeling, Monte Carlo methods, finite-element techniques, density functional theory, integrated computational materials engineering (ICME), and machine learning methods
(5) Microstructural control, including hierarchical structuring, which modifies the physical and mechanical behavior
(6) Applications of material properties in the aerospace, automotive, biomedical, and energy industries
