Abstract
A novel precipitation-strengthened multicomponent Ni-rich Ni46.23Co23Cr10Fe5Al8.5Ti4W2Mo1C0.15B0.1Zr0.02 (at.%) high-entropy alloy (HEA) was designed with strain-hardening after yielding rather than strain-softening even at the temperature of 1000°C. Due to the rapid onset of intergranular cracking, the HEA with spherical precipitates and straight grain boundaries was brittle, exhibiting an inferior tensile strength of ~220 MPa, and an...
