A critical review of high entropy alloys and related concepts High entropy alloys (HEAs) are barely 12 years old. The field has stimulated new ideas and has inspired the exploration of the vast composition space offer... D.B. Miracle a,O.N. Senkov a b - 《Acta Materialia》 被引量: 26...
金属高熵材料(Metallic high-entropy materials, HEMs),又称高熵合金(high-entropy alloys, HEAs),多成分合金(multicomponent alloys),多主元合金(multi-principal element alloys),组成复杂合金(compositionally complex alloys, CCAs),无基元合金(baseless alloys, BAs)等自2004年问世以来得到科学家的广泛关注与研究。...
High-Entropy Alloys are advanced materials composed of more than four principal elements, known for their unique properties such as exceptional mechanical strength, corrosion resistance, and thermal stability. These alloys are utilized in various applications like catalysis, energy storage, and magnetic ma...
While such a single-phase structure can occur in unique systems, it is now appreciated that the definition of high entropy alloys can be broader, with systems comprising only four elements possible of forming single phases, and most five (or more) element systems actually being multi (>2) ...
This book provides a systematic and comprehensive description of high-entropy alloys (HEAs). The authors summarize key properties of HEAs from the perspective of both fundamental understanding and applications, which are supported by in-depth analyses. The book also contains computational modeling in ta...

For the past decade and a half, however, a new alloying strategy that involves the combination of multiple principal elements in high concentrations to create new materials called high-entropy alloys has been in vogue. The multi-dimensional compositional space that can be tackled with this ...
High-entropy alloys (HEAs) with an atomic arrangement of a hexagonal close-packed (hcp) structure were found in YGdTbDyLu and GdTbDyTmLu alloys as a nearly single hcp phase. The equi-atomic alloy design for HEAs assisted by binary phase diagrams started with selecting constituent elements with...
