Abstract
Recent material design aims at fabricating heterogeneous structures to overcome the strength-ductility trade-off. A severe plastic deformation process is adopted to a multi-interstitial high-entropy alloy to form precipitate-rich and precipitate-lean domains. By this approach, the alloy achieved a yield strength of ∼1020 MPa with a tensile elongation of ∼34 %.
