Dual-Phase Heterostructured High-Entropy Alloy

Synergistic Strength-Ductility Boost

A heterogeneous soft-hard interface, achieved via cold rolling and short-time annealing, synergistically delivers 770 MPa tensile strength and 25.4% uniform elongation through multiple deformation mechanisms that overcome the strength-ductility trade-off.
