摘要

Introducing coherent precipitates is an important method to strengthen alloys. Recently, it is found that the introduction of coherent B2 phase in multi-principal element alloys with BCC structure can improve the mechanical properties significantly, developing a new class of important series alloys. The up-to-date knowledge of these alloys from the perspectives of composition, microstructure, phase stability, and mechanical properties was summarized. These alloys exhibit high yield strength over a wide temperature regime, but the ductility presents different characterization due to the compositional difference. At present, their engineering application is limited due to their weaker thermal stability at elevated temperature, especially above 500℃, and furthermore, the design of compositional content appears to be more easy method to resolve the problem. This paper aims at providing guidance to further design of multi-principal element alloys with coherent BCC/B2 dual-phases.
