摘 要：The microstructure and tensile properties of FexCo Cr Ni Mn high-entropy alloys（HEAs） were investigated.It was found that the FexCo Cr Ni Mn HEA has a single face-centered cubic（fcc） structure in a wide range of Fe content. Further increasing the Fe content endowed the FexCo Cr Ni Mn alloys with an fcc/bodycentered cubic（bcc） dual-phase structure. The yield strength of the FexCo Cr Ni Mn HEAs slightly decreased with the increase of Fe content. An excellent combination of strength and ductility was achieved in the FexCo Cr Ni Mn HEA with higher Fe content, which can be attributed to the outstanding deformation coordination capability of the fcc/bcc dual phase structure.
