Results indicate that pitting corrosion should be responsible for the severe degradation of the tensile properties including yield strength, tensile strength (corrosion residual strength), and elongation within the testing time. The extreme depth of the corrosion pit was statistically related to corrosion residual strength. The variation of corrosion residual strength exhibited an exponential decay trend from 0 to 72 h. Furthermore, heat treatment enhanced the corrosion resistance of the GW63K alloy by inhibiting both the initiation and growth of corrosion pits, thereby improving the corrosion residual strength of the alloy. The critical working strength of GW63K alloy was significantly improved (increased to 192 MPa from 132 MPa) via heat treatment.<\/jats:p>","DOI":"10.3390\/ma18102244","type":"journal-article","created":{"date-parts":[[2025,5,12]],"date-time":"2025-05-12T10:58:07Z","timestamp":1747047487000},"page":"2244","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Study on the Effect of Corrosion on Tensile Properties of GW63K Magnesium Alloy"],"prefix":"10.3390","volume":"18","author":[{"given":"Tian","family":"Lan","sequence":"first","affiliation":[{"name":"State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, 30 Xueyuan Road, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8808-9075","authenticated-orcid":false,"given":"Feng","family":"Ye","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, 30 Xueyuan Road, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Binbin","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, 30 Xueyuan Road, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haoyang","family":"Du","sequence":"additional","affiliation":[{"name":"State Grid Jilin Electric Power Research Institute, No. 4433 Renmin Street, Changchun 130021, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"350","DOI":"10.1016\/j.actamat.2012.09.067","article-title":"Direct observation of dislocation dissociation and Suzuki segregation in a Mg\u2013Zn\u2013Y alloy by aberration-corrected scanning transmission electron microscopy","volume":"61","author":"Yang","year":"2013","journal-title":"Acta Mater."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/j.jma.2020.02.003","article-title":"Latest research advances on magnesium and magnesium alloys worldwide","volume":"8","author":"Song","year":"2020","journal-title":"J.
