Triple-Phase Eutectic High-Entropy Alloy: Al 10 Co 18 Cr 18 Fe 18 Nb 10 Ni 26
2021
A triple-phase eutectic high-entropy alloy (TEHEA) Al10Co18Cr18Fe18Nb10Ni26 is designed and successfully prepared by electric arc melting. The alloy is proved to consist of disordered face-centered cubic (FCC) phase, ordered body centered cubic (B2) phase and Laves phase with hexagonal close-packed (HCP) structure. Furthermore, a simple mixing method can be adopted to design TEHEAs and to locate the eutectic point composition. This class of alloys provides a new approach for the exploration of multicomponent triple-phase eutectic alloys with unique microstructure and properties.
