The alloys subjected to natural aging (NA) demonstrated significantly enhanced ductility at equivalent stress levels compared to those subjected to artificial aging (AA). In AA-treated alloys, \u03b7\u2032 and \u03b7-phases with incoherent interfaces were formed, while GP zones and solute clusters were dominantly exhibited in the NA-treated alloy with a coherent interface with the matrix. Due to the change in interface bonding, the dislocation movement and pinning behavior after deformation are varied depending on the aging conditions of Al\u2013Mg\u2013Zn alloy sheet. Thus, the elongation to fracture of the NA alloy sheet was improved compared to that of the AA alloy sheet because of the enhanced work-hardening capacity and the thin precipitate-free zone (PFZ). Deformation textures and dislocation densities varied between NA and AA treatments, as revealed by electron backscatter diffraction (EBSD) and kernel average misorientation (KAM) analysis. The interactions between the precipitates, dislocations, and the PFZ in the AA- and NA-treated alloys were analyzed via transmission electron microscopy (TEM). The insights gained from this research provide a valuable foundation for industrial applications, particularly in sectors demanding lightweight, high-strength materials, where optimizing the aging process can lead to significant performance improvement and cost savings.<\/jats:p>","DOI":"10.3390\/ma17184478","type":"journal-article","created":{"date-parts":[[2024,9,12]],"date-time":"2024-09-12T08:04:09Z","timestamp":1726128249000},"page":"4478","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Natural and Artificial Aging Effects on the Deformation Behaviors of Al\u2013Mg\u2013Zn Alloy Sheets"],"prefix":"10.3390","volume":"17","author":[{"given":"Kwangmin","family":"Choi","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 03722, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sangjun","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 03722, Republic of Korea"},{"name":"Institute of Industrial Science, The University of Tokyo, 4-6-1 Komaba, Meguro 153-8505, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donghyun","family":"Bae","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, Yonsei University, Seoul 03722, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"577","DOI":"10.1016\/j.jallcom.2016.12.269","article-title":"Castability and mechanical properties of new 7xxx aluminum alloys for automotive chassis\/body applications","volume":"698","author":"Shin","year":"2017","journal-title":"J.
