Abstract

This work shows a CoCrFeMnNi0.8V high entropy alloy (HEA) with multiple length-scale hierarchical microstructure, obtained upon cooling at ∼ 62.5 K/s, consisting of a dominant globular sigma phase, FCC matrix and V-rich particles. The novel microstructure, never reported before for the CoCrFeMnNiV system, results in about a fourfold and sixfold increase of hardness and wear resistance, respectively, compared to that of CoCrFeMnNi alloy.
