The short-term and long-term corrosion behaviours of these alloys in 3.5 wt.% NaCl solution were studied by electrochemical impedance spectroscopy, potentiodynamic polarisation measurement, immersion test and corrosion morphology analysis. The results show that all the designed HEAs present single-phase FCC structure, and the increase in Cr content changes the microstructural morphology from cellular to a typical dendritic\u2013interdendritic state. Without the influence of phase transformation, the corrosion resistance of Al0.3FeCoNiCrx HEAs gradually increases with the increase in Cr content. Our designed alloys exhibit excellent corrosion resistance compared to the existing HEAs in the AlFeCoNiCr composition system.<\/jats:p>","DOI":"10.3390\/ma17215259","type":"journal-article","created":{"date-parts":[[2024,10,29]],"date-time":"2024-10-29T06:29:57Z","timestamp":1730183397000},"page":"5259","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Phase, Microstructure and Corrosion Behaviour of Al0.3FeCoNiCrx High-Entropy Alloys via Cr Addition"],"prefix":"10.3390","volume":"17","author":[{"given":"Mengyao","family":"Chen","sequence":"first","affiliation":[{"name":"China Institute of Atomic Energy, Beijing 102413, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haicheng","family":"Shen","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Guangdong Ocean University, Zhanjiang 524000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7179-8430","authenticated-orcid":false,"given":"Cheng","family":"Wen","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Guangdong Ocean University, Zhanjiang 524000, China"},{"name":"Zhanjiang Key Laboratory of Corrosion and Protection for Ocean Engineering and Equipment, Guangdong Ocean University, Zhanjiang 524000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nanchuan","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Guangdong Ocean University, Zhanjiang 524000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuwan","family":"Tian","sequence":"additional","affiliation":[{"name":"College of Mechanical Engineering, Guangdong Ocean University, Zhanjiang 524000, China"},{"name":"Zhanjiang Key Laboratory of Corrosion and Protection for Ocean Engineering and Equipment, Guangdong Ocean University, Zhanjiang 524000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weihua","family":"Zhong","sequence":"additional","affiliation":[{"name":"China Institute of Atomic Energy, Beijing 102413, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2801-2535","authenticated-orcid":false,"given":"Haiyou","family":"Huang","sequence":"additional","affiliation":[{"name":"Institute for Advanced Materials and Technology, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1002\/adem.200300567","article-title":"Nanostructured high-entropy alloys with multiple principal elements: Novel alloy design concepts and outcomes","volume":"6","author":"Yeh","year":"2004","journal-title":"Adv.
