Abstract

We prepared a novel cast high-entropy alloy (HEA) that comprises a dual-phase microstructure with L1₂ and B2 phases. Our designed HEA achieved a remarkable strength–ductility balance (tensile strength of ∼1025 MPa and uniform elongation of ∼30 %, which well outperforms many as-cast HEAs including arc-melting and directly cast HEAs.
