High-Entropy Materials: Theory, Experiments, and Applications
This book discusses fundamental studies involving the history, modelling, simulation, experimental work, and applications on high-entropy materials. Topics include data-driven and machine-learning approaches, additive-manufacturing techniques, computational and analytical methods, such as density functional theory and multifractal analysis, mechanical behavior, high-throughput methods, and irradiation effects. The types of high-entropy materials consist of alloys, oxides, and ceramics. The book then concludes with a discussion on potential future applications of these novel materials.
Fundamentals of Multicomponent High-Entropy Materials

Release Date: 2024-11-13
Human development has been a continuing attempt to use new materials in ever more sophisticated ways to enhance the quality of human life. Throughout history, we have made materials with a main component based on the principal property required, with small alloying additions to provide secondary properties. But recently, there has been a revolution as we have discovered how to make much more complex mixtures, providing completely new materials, requiring entirely new scientific theories, and massively extending our ability to make useful products. These new materials are called multicomponent or high-entropy materials. This is the first textbook on the fundamentals of these new multicomponent high-entropy materials. It includes contextual chapters on the history and future potential for developing humankind as driven by the discovery of new materials, and core chapters on methods for discovering and manufacturing multicomponent high-entropy materials, their underlying thermodynamic and atomic and electronic structures, their physical, mechanical and chemical properties, and their potential applications. This book concentrates on the main new concepts and theories that have been developed. It is written by the scientist who first discovered multicomponent high-entropy materials, and covers how to make them as well as their structures, properties and potential applications, providing an overview and a summary of the state of play for researchers as well as for students and newcomers entering the field.
High-Entropy Alloys
This book provides a complete review of the current state of the art in the field of high entropy alloys (HEA). The conventional approach to alloy design is to select one principal element and add elements to it in minor quantities in order to improve the properties. In 2004, Professor J.W. Yeh and his group first reported a new approach to alloy design, which involved mixing elements in equiatomic or near-equiatomic proportions, to form multi-component alloys with no single principal element. These alloys are expected to have high configurational entropy and hence were termed as "high entropy alloys." HEAs have a broad range of structures and properties, and may find applications in structural, electrical, magnetic, high-temperature, wear-resistant, corrosion-resistant, and oxidation-resistant components. Due to their unique properties, high entropy alloys have attracted considerable attention from both academics and technologists. This book presents the fundamental knowledge present in the field, the spectrum of various alloy systems and their characteristics studied to date, current key focus areas, and the future scope of the field in terms of research and technological applications. - Encompasses the synthesis and phase formation of high entropy alloys - Covers design of HEAs based on thermodynamic criteria - Discusses the structural and functional properties of HEAs - Provides a comparison of HEAs with other multicomponent systems like intermetallics and bulk metallic glasses
