A comprehensive introduction to high-entropy materials (HEMs) - a revolutionary class of materials characterized by multiple principal elements and exceptional configurational entropy. This series covers fundamental concepts, types, synthesis methods, properties, and emerging applications.
High-entropy materials represent a paradigm shift in materials design. Unlike conventional alloys based on one or two principal elements, HEMs contain multiple elements in near-equimolar ratios, creating vast compositional spaces with unprecedented properties. Since their discovery in 2004, these materials have attracted intense research interest due to their remarkable mechanical, thermal, and functional properties.
Introduction to high-entropy materials concepts, history, and the four core effects that govern their unique properties. Understanding configurational entropy and phase formation.
Exploring the diverse family of HEMs including high-entropy alloys, ceramics, and oxides. Understanding composition design strategies and emerging material classes.
Comprehensive overview of synthesis techniques from arc melting and mechanical alloying to additive manufacturing and solution-based methods for different HEM types.
Understanding the mechanical, thermal, and functional properties of HEMs. Overview of characterization techniques and computational approaches for property prediction.
Current and emerging applications of HEMs in aerospace, energy, catalysis, and biomedical fields. Discussion of future directions and machine learning-accelerated discovery.
