The resultant Al<sub>3</sub>Sc phase is believed to help resist corrosion. However, when it comes to the Sc-microalloyed Al-Cu system, the complex phase transformation has rarely been studied, leaving its impacts on corrosion behavior controversial. In this paper, A206 and A206 microalloyed with Sc are fabricated to study the phase transformation’s effects on corrosion at peak-aged state (T6). Our results find that Al-Cu-Sc based eutectic phases form at the grain boundaries (GBs) after solidification. Then, these GB phases turn to stabler but adjacent θ-Al<sub>2</sub>Cu, W-Al<sub>8</sub>Cu<sub>4</sub>Sc, and other complex phases after heat treatment. Due to the large difference in diffusion rates of Sc and Cu during heat treatment, the Al<sub>3</sub>Sc forms and distributes inhomogeneously inside the grains but near the GBs. Cu distributes more evenly within the grains, while its θ′-Al<sub>2</sub>Cu can preferentially precipitate at the interface of Al and Al<sub>3</sub>Sc after aging. The abovementioned phase transformation, even with the resultant beneficial nanoscale Al<sub>3</sub>Sc, degrades Sc-microalloyed Al-Cu’s corrosion performance, because the closely-located complex GB phases and the unevenly distributed Al<sub>3</sub>Sc favorably nucleating interfacial θ′-Al<sub>2</sub>Cu inside the grain can accelerate the intergranular corrosion (IGC), promoting the corrosion-induced cracks. Our methodology by multiscale experimental characterization and atomic-scale simulation validation critically evaluates the reasons behind the unpredictable corrosion performance in Al-Cu alloy with Sc by a clear phase distribution picture, instead of a mere phase composition consideration, which can enlighten better microalloying designs facing corrosive environment applications.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"255 ","pages":"Article 113152"},"PeriodicalIF":7.4,"publicationDate":"2025-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144523082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous research primarily focused on its influence on two-dimensional, static surface corrosion, neglecting the evolution of corrosion behavior from the surface to the interior. Therefore, three-dimensional (3D) and dynamic observations are essential to comprehensively understand the underlying mechanism. Using Mg-0.6Al-0.2Ca-0.3Mn (wt.%) (AXM) as a model alloy, we investigated the effect of crystallographic orientation on corrosion in a 3.5 wt.% NaCl solution across temporal and spatial scales by combining laboratory-based diffraction contrast tomography (Lab-DCT), and quasi in-situ computed tomography (CT). During early immersion, basal-oriented planes, influenced by the galvanic effect of the second-phase particles and non-basal-oriented planes, exhibited greater susceptibility to local corrosion, which then propagated towards adjacent near-basal-oriented planes. The loose, porous corrosion product film formed on basal-oriented grains facilitated deeper corrosion penetration over time, extending to surrounding grains with similar orientations. Prolonged immersion resulted in a higher corrosion volume percentage within basal-oriented grains. These findings underscore the crucial role of crystallographic orientation in controlling localized corrosion behavior, providing valuable theoretical insights for enhancing the corrosion resistance of magnesium alloys through crystallographic orientation distribution control.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"255 ","pages":"Article 113151"},"PeriodicalIF":7.4,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144501824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
