Achieving a remarkable strength–ductility combination in a novel casting AlCoCrNi high entropy alloy

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 ar...

Zusammenfassung:	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.
