Enhancing strength-ductility synergy in a casting non-equiatomic NiCoCr-based high-entropy alloy by Al and Ti combination addition
Abstract
A non-equiatomic Ni3.5Co3Cr1.5 medium-entropy alloy (AT0) with a single-phase face-centered cubic structure (FCC) directly obtained by arc-melting shows the low yield strength of 147 MPa, ultimate tensile strength of 447 MPa and large total elongation to fracture of 78.8%. By doping Al and Ti, the as-cast (Ni3.5Co3Cr1.5)90Al5Ti5 high-entropy alloy (AT5) exhibits enhanced strength-ductility synergy. Compared to AT0 alloy, the yield strength of...
