High-Entropy Alloys, Second Edition provides a complete review of the current state of the field of high entropy alloys (HEA). Building upon the first edition, this fully updated release includes new theoretical understandings of these materials, highlighting recent developments on modeling and new classes of HEAs, such as Eutectic HEAs and Dual phase HEAs. Due to their unique properties, high entropy alloys have attracted considerable attention from both academics and technologists. This book presents the fundamental knowledge, the spectrum of various alloy systems and their characteristics, key focus areas, and the future scope of the field in terms of research and technological applications.

Provides an up-to-date, comprehensive understanding on the current status of HEAs in terms of theoretical understanding and modeling efforts
Gives a complete idea on alloy design criteria of various classes of HEAs developed so far
Discusses the microstructure property correlations in HEAs in terms of structural and functional properties
Presents a comparison of HEAs with other multicomponent systems, like intermetallics and bulk metallic glasses

Dr. B.S. Murty is a Professor, Department of Metallurgical and Materials Engineering, IIT Madras, Chennai, India. He has pioneered the synthesis of nanocrystalline materials by mechanical alloying route. His other important contributions are in the field of bulk metallic glasses and in-situ composites. He has co-authrored a Text Book on Nanoscience and Nanotechnology. He has also made significant contributions to the field of high-entropy alloys. Jien-Wei Yeh is a pioneering materials scientist whose expertise spans aluminum and magnesium alloys, metal matrix composites, metallic glasses, coatings, reciprocating extrusion, and high-entropy materials (HEMs). Since 1995, he has led groundbreaking research that redefined alloy design by proposing material compositions beyond traditional boundaries, unlocking vast compositional possibilities across the Periodic Table. He coined and defined “high-entropy alloys (HEAs), established their four core effects, and laid the theoretical foundation for this rapidly expanding field. His work further extended high-entropy concepts to ceramics, polymers, and composites, catalyzing global development of high-entropy materials. He has been elected as an academician in Academia Sinica, and has received many prestigious awards, including the Executive Yuan Award for Outstanding Science and Technology Contribution (2021) and the Taiwan Presidential Scientific Award (2025). In Stanford’s global rankings in scientific influence, he ranked second worldwide in Materials.Dr. Srinivasa Ranganathan is NASI Platinum Jubilee Fellow at the Indian Institute of Science, Bangalore. His academic career as an educator and researcher in metallurgy for the past four decades at the Banaras Hindu University and the Indian Institute of Science has been stellar. He has made significant contributions to our understanding of the structure of interfaces, quasicrystals, bulk metallic glasses and nanostructured materials. He has co-authored a book on New Geometries for New Materials. Dr. Pinaki Bhattacharjee is an Associate Professor in the Department of Materials Science and Engineerinng at the Indian Institute of Technology Hyderabad. His research interests include deformation and restoration behaviour of metallic materials, as well as crystallographic texture, and the application of high resolution Electron Back Scatter Diffraction (EBSD) and Transmission Electron Microscopy (TEM) techniques in materials characterization.
