By incorporating varying concentrations of Sr (0.01 wt.% and 0.05 wt.%), the morphological and corrosion behaviours of the alloy were analysed under different corrosive environments, including sulphuric acid, sodium hydroxide, and sodium chloride solutions. The results demonstrate that Sr modifications significantly enhance the alloy\u2019s corrosion resistance, with the most substantial improvement observed at 0.05 wt.% Sr. The analysis revealed that the weight loss of the alloy in sulphuric acid decreased by 2.5% with 0.05 wt.% Sr after 10 days of immersion, due to the formation of a stable passive oxide layer. In sodium hydroxide, however, the weight loss was reduced by 5% with 0.05 wt.% Sr after 10 days, indicating aggressive uniform corrosion. In the 3.5% sodium chloride solution, the corrosion rates remain relatively low, and the 0.05 wt.% Sr alloy showed a decrease in corrosion product formation over time, suggesting enhanced resistance. Detailed surface analyses, including 3D profiling and morphology assessments, revealed that Sr additions refine the eutectic silicon phase, transforming it from a coarse to a more desirable fibrous or lamellar structure, thus improving the alloy\u2019s overall performance. The innovative findings underscore the potential of Sr as an effective microstructural modifier for enhancing the durability and longevity of Al-Si alloys in corrosive environments.<\/jats:p>","DOI":"10.3390\/ma17194923","type":"journal-article","created":{"date-parts":[[2024,10,9]],"date-time":"2024-10-09T07:39:52Z","timestamp":1728459592000},"page":"4923","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Effects of Strontium Modification on Corrosion Resistance of Al-Si Alloys in Various Corrosive Environments"],"prefix":"10.3390","volume":"17","author":[{"given":"Lau Lin","family":"Jie","sequence":"first","affiliation":[{"name":"Centre for Manufacturing and Environmental Sustainability, Faculty of Engineering and Technology, Multimedia University, Bukit Beruang, Malacca 75450, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1643-368X","authenticated-orcid":false,"given":"Mirza Farrukh","family":"Baig","sequence":"additional","affiliation":[{"name":"Centre for Manufacturing and Environmental Sustainability, Faculty of Engineering and Technology, Multimedia University, Bukit Beruang, Malacca 75450, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ervina Efzan","family":"Mhd Noor","sequence":"additional","affiliation":[{"name":"Centre for Manufacturing and Environmental Sustainability, Faculty of Engineering and Technology, Multimedia University, Bukit Beruang, Malacca 75450, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"171","DOI":"10.1080\/10408436.2018.1549975","article-title":"Casting lightweight stiff aluminum alloys: A review","volume":"45","author":"Amirkhanlou","year":"2020","journal-title":"Crit.
