  • A multi-level ordered structure strategy mimicking biological multi-structural features, concurrently unlocks multiple physical property limits. This new paradigm transcends traditional compositional design strategies to break performance bottleneck.

  • There is a lack of guiding parameters to design metallic materials such as high-entropy alloys with strength-ductility synergy. Here, the authors propose such an effective parameter κ, the ratio of short-ranged interactions between closed-pack planes, experimentally validated by six alloys.

  • Transmission electron microscopy reveals the electroplastic effects in a Ti–Al alloy, which can be uncoupled from Joule heating effects. Electropulsing during deformation enhances wavy slip of dislocations, reconfiguring the dislocation pattern, and hence increases the ductility.

  • Metal alloys consisting of three or more major elemental components show enhanced mechanical properties, which are now shown to be correlated with short-range order observed with electron microscopy.

  • Amorphization can be an additional mechanism to assist plastic deformation in crystalline materials, providing a strategy to improve the load-bearing ability of brittle materials.

  • Individual addition of O or Al is known to deteriorate ductility of Ti alloys, especially at cryogenic temperatures. Here the authors demonstrate a counter-intuitive effect where significant addition of both Al and O substantially improves both strength and ductility in a Ti-6Al-0.3 O ternary alloy.
