Topic: Microstructure-Driven Design of High-Entropy Materials and Energies

The rapid development of advanced materials and energy technologies has stimulated growing interest in high-entropy design strategies, which utilize multiple principal elements to create materials with high compositional complexity and unique microstructural features. These strategies provide new opportunities to control phase formation and stability, engineer defects, and tailor microstructures, thereby enabling significant improvements in material performance. Applications include structural materials with ultralow thermal expansion, efficient catalysis, and high-energy batteries, particularly under extreme conditions such as ultrahigh or ultralow temperatures, high strain rate loading, irradiation, and corrosive environments.

This Special Issue aims to highlight recent advances in the design and optimization of materials driven by high-entropy concepts. We invite contributions focused on microstructural regulation, phase stability, defect engineering, and the underlying structure-property relationships in high-entropy systems. We also encourage studies involving experimental synthesis, advanced characterization techniques, or computational modeling, which can provide deeper insights into microstructure evolution and performance optimization.

By bringing together interdisciplinary research, this Special Issue seeks to promote the development of high-entropy materials and provide guidance for microstructure-driven materials design across diverse systems. These include high-entropy and medium-entropy alloys and compounds in various forms, such as zero-dimensional (0D) particles, one-dimensional (1D) wires and fibers, two-dimensional (2D) films and coatings, and three-dimensional (3D) bulk materials.
