Abstract
This study investigated the post-drawn annealed CoCuFeMnNi high-entropy wires with distinct dual phase structure and B2 nanoprecipitates. The exceptional hardness observed of the post-drawn annealed CoCuFeMnNi wires can be attributed to the synergetic effect of the ultrafine-grained (UFG) structure and nanoscale precipitation/heterogeneity in the post-drawn annealed CoCuFeMnNi wires.
