Microstructure and mechanical properties of Fe CoCrNiMn high-entropy alloys

The microstructure and tensile properties of Fe x CoCrNiMn high-entropy alloys (HEAs) were investigated. It was found that the Fe x CoCrNiMn HEA has a single face-centered cubic (fcc) structure in a wide range of Fe content . Further increasing the Fe content endowed the Fe x CoCrNiMn alloys with an fcc/body-centered cubic (bcc) dual-phase structure. The yield strength of the Fe x CoCrNiMn HEAs slightly decreased with the increase of Fe content....
