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, Prof. 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 structure 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 academicians and technologists. Thsi book presents the fundamental knowledge present in the field, the spectrum of various alloy systems and their characteristics studied till date, current key-focus areas, and future scope of the field in terms of research and technological applications. Encompasses the synthesis and phase formation of high entropy alloysCovers design of HEAs based on thermodynamic criteriaDiscusses the structural and functional properties of HEAsProvides a comparison of HEAs with other multicomponent systems like intermetallics and bulk metallic glasses INDICE: Chapter 1: Introduction - Historical evolution of alloys; Chapter 2: Synthesis of high entropy alloys; Chapter 3: Phase formation in equiatomic high entropy alloys; Chapter 4: Phase formation in non-equiatomic high entropy alloys; Chapter 5: Designing of high entropy alloys; Chapter 6: Structural properties of high entropy alloys; Chapter 7: Functional properties of high entropy alloys; Chapter 8: Multicomponent intermetallis and quasicrystals; Chapter 9: Multicomponent Bulk Metallic Glasses; Chapter 10: Future directions
