Advanced Science, EarlyView.A CoCrFeNiTa0.4 eutectic high‐entropy alloy achieves a near‐theoretical yield strength of 2.6 GPa with 13.6% plasticity. This breakthrough stems from a hierarchical nanostructure (FCC‐Laves lamellae with L12/D022 precipitates), which alleviates the inter‐phase modulus/hardness mismatch through synergistic strengthening and toughening, guiding the ...

Advanced Science, EarlyView.A novel “Cu‐mediated interstitial site engineering” strategy is introduced to thermodynamically stabilize hexagonal oxygen (hex‐O) configurations in oxygen‐containing titanium alloys. The hex‐O configuration activates multiple slip systems and enhances dislocation pinning via long‐range repulsion.
