Overview of high-entropy alloys

Abstract

New materials and alloys are being developed by using latest technology and manufacturing techniques. Significant progress in alloy system has led to development of special alloys, such as alloys of iron, copper, superalloys, and high-entropy alloys. High-entropy alloys with multiple constituent elements, higher mixing entropy, improved property, and structure make them different from other alloy systems. High-entropy alloy concepts have come into focus after successful development of these alloys, from 2004. Basic concepts, design strategy, phase formation rule, and basic core effects for enhancements of property and structural stability of highentropy alloys are discussed in this chapter. © 2023 Walter de Gruyter GmbH, Berlin/Boston.
