摘要

Abstract

BSTRACTWe developed a series of Co-rich Co

(FeNi)

75−x

(

= 35

65) high entropy alloys with improved strength and/or ductility

derived from lowering the stacking fault energy (SFE) and reducing the fcc phase stability of the equiatomic CoCrFeNi alloy. Thermodynamics and

ab initio

calculations demonstrated that increasing Co while decreasing Fe and Ni concentrations lower the SFE and reduce the fcc phase stability. The Co

and Co

alloys with single fcc phase

exhibit superior tensile properties

contributing to the twinning and fcc → hcp martensitic transformation. The present study offers a guideline for designing high-performance high entropy alloys.
