We found that a metal (gold) containing spherical voids with a fraction of up to 10% does not fracture prematurely in tension when the voids are shrunk to the submicron or nanometer scale. Instead, the dispersed nanovoids increase the strength and ductility of the material while simultaneously reducing its weight. Apart from the suppressed stress or strain concentration, such structure provides enormous surface area and promotes surface-dislocation interactions, which enable strengthening and additional strain hardening and thus toughening. Transforming voids from crack-like detrimental defects into a beneficial \u201cingredient\u201d provides an inexpensive and environmentally friendly approach for the development of a new class of lightweight, high-performance materials.<\/jats:p>","DOI":"10.1126\/science.abo7579","type":"journal-article","created":{"date-parts":[[2024,8,8]],"date-time":"2024-08-08T18:06:46Z","timestamp":1723140406000},"page":"629-633","update-policy":"https:\/\/doi.org\/10.34133\/aaas_crossmark","source":"Crossref","is-referenced-by-count":78,"title":["Strengthening gold with dispersed nanovoids"],"prefix":"10.1126","volume":"385","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-3587-8381","authenticated-orcid":true,"given":"Jia-Ji","family":"Chen","sequence":"first","affiliation":[{"name":"Shenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, Shenyang, P.R.
