Abstract

Abstract

The evolution of the microstructure and tensile properties of dual-phase Al_0.6CoCrFeNi high-entropy alloys (HEAs) subjected to cold rolling was investigated. The homogenized Al_0.6CoCrFeNi alloys consisted of face-centered-cubic and body-centered-cubic phases, presenting similar mechanical behavior as the as-cast state. The yield and tensile strengths of the alloys could be dramatically enhanced to ~1205 MPa and ~1318 MPa after 50% rolling reduction, respectively. A power-law relationship was discovered between the strain-hardening exponent and rolling reduction. The tensile strengths of this dual-phase HEA with different cold rolling treatments were predicted, mainly based on the Hollomon relationship, by the strain-hardening exponent, and showed good agreement with the experimental results.
