It was found that CLP induced a higher amplitude of compressive residual stress and improved the nano-hardness and the elastic modulus. Compared to the LP-ed samples, the fatigue life of the CLP-ed specimens was higher, and the initiation and propagation of fatigue cracks were more effectively inhibited. Therefore, CLP can effectively improve the fatigue performance of aluminum alloys.\n                  <\/jats:p>","DOI":"10.1364\/ao.462545","type":"journal-article","created":{"date-parts":[[2022,7,20]],"date-time":"2022-07-20T10:30:08Z","timestamp":1658313008000},"page":"7307","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Vibration fatigue life and fracture analysis of 2024-T351 aluminum alloy treated by cryogenic laser peening"],"prefix":"10.1364","volume":"61","author":[{"given":"Hansong","family":"Chen","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03jc41j30","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xumin","family":"Leng","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03jc41j30","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangyang","family":"Xu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03jc41j30","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6341-0654","authenticated-orcid":true,"given":"Xiankai","family":"Meng","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03jc41j30","id-type":"ROR","asserted-by":"publisher"}]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"285","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"key":"ao-61-25-7307-R1","doi-asserted-by":"crossref","DOI":"10.1007\/978-981-10-2134-3_2","article-title":"Aluminium alloys for aerospace applications","volume-title":"Aerospace Materials and Material Technologies","author":"Rambabu","year":"2017"},{"key":"ao-61-25-7307-R2","doi-asserted-by":"publisher","first-page":"33","DOI":"10.1016\/j.ijfatigue.2004.06.010","volume":"27","author":"Merati","year":"2005","journal-title":"Int.
