This talk discusses how to fill the blank space in the strength-ductility Ashby diagram, pushing the envelope towards 2 GPa yield strength in combination with 30% uniform tensile elongation [Nature 643 (2025)119]. In particular, we leverage additional strengthening and strain hardening mechanisms enabled by the expanded scope of elements and their compositions in multi-principal-element alloys, on top of previously known plasticity mechanisms. By intelligently doing so, complex concentrated alloys achieve yield strength rivaling ultrahigh strength steel and at the same time tensile ductility akin to unhardened elemental metal, synergistically reaching both coveted properties [Science Advances (2026) DOI: 10.1126/sciadv.aeb7908]. |
