This study demonstrates how multi-phase precipitation engineering synergistically enhances hydrogen resistance in duplex-aged Ferrium S53 steel through coupled experiments and simulations. TDS analysis identifies three distinct hydrogen desorption peaks corresponding to trapping at martensitic substructures, austenite interfaces, and nanoprecipitates, with the secondary-aged condition showing enhanced trapping capacity. Microstructural engineering through optimized aging generates high-density <em>M</em>₂C/α'<sub>Cr</sub> nanoprecipitates and stabilized austenite, shifting hydrogen desorption peaks to higher altitudes and reducing mobile hydrogen populations. Fracture analysis demonstrates the competing roles of plasticity-mediated and decohesion mechanisms, with their relative dominance evidenced by hybrid fracture features combining intergranular cracking with localized plasticity markers. First-principles calculations reveal Mo-modified carbides exhibit reduced vacancy formation barriers while increased hydrogen binding energy. The coordinated microstructure design achieves superior embrittlement resistance through: (i) TDS-verified hydrogen capture at engineered reversible traps, (ii) dislocation pinning that impedes hydrogen transport, and (iii) suppression of critical hydrogen accumulation at vulnerable interfaces.

Here, we present a fully automated, image-based, data-driven framework for analyzing corrosion progression under thousands of droplets simultaneously. Using time-resolved optical imaging and pre-trained large vision models for droplet segmentation, we construct per-droplet color features and propose a probability-based representation of corrosion product formation in inner and outer regions of interest. This approach overcomes the limitations of binary classification by capturing the continuous and spatially heterogeneous nature of corrosion product formation. Applied to carbon steel exposed to over 1500 pre-sprayed 1 M NaCl droplets of various sizes, the method reveals that the probability of corrosion product presence strongly depends on droplet size, with larger droplets more likely to exhibit products both under and around the droplet footprint. Moreover, corrosion products in the outer region can appear independently of under-droplet corrosion, suggesting a role for inter-droplet interactions. By transforming raw imaging data into physically meaningful per-droplet metrics, this work offers a scalable platform for investigating localized corrosion kinetics and morphology in complex, real-world droplet populations, opening new opportunities for connecting droplet formation and population behavior to local and overall atmospheric corrosion rates.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"258 ","pages":"Article 113313"},"PeriodicalIF":7.4,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145264102","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}

However, without quantitative analysis of individual contributions of alloying elements and their combined effects, the corrosion resistance alloy design is always performed by trial-and-error process. In this study, we have quantified the effects of binary, ternary and quaternary additions of Y, Ce, and Mn to Mg alloys and found that their electrochemical performances are not only a function of simple dissolution but also their existing states by microstructure quantification before and after immersion tests. Using first-principles calculations, we have found that the beneficial effects of Rare Earth (RE) elements, such as Ce, and Y, can only be effective when they form secondary phases and act as the anode to form oxide films in front of Mg matrix; while dissolution of Mn can actually passivate the cathodic activity and improve the work function of the matrix (from 3.66 eV to 3.80 eV). Measurements of as-cast Mg-2Y-0.5Ce-0.5Mn alloy exhibit the best corrosion resistance (0.395 mm/y), due to both reduction of galvanic corrosion sites and protection of RE-containing oxides.

The effects of cross-rolling (CR) at reduction ratios of 20 %, 40 %, and 80 % on the microstructural evolution and corrosion behavior were systematically investigated.

Here, the oxide films formed on a sensitized 5083 Al-Mg alloy under constant elastic and plastic tensile stresses are investigated. Pitting corrosion and intergranular corrosion occurred on the alloy surface. Tensile stress accelerated the anodic dissolution on the alloy surface and promoted intergranular corrosion, weakening the corrosion resistance of the oxide film. A heterogeneous oxide film was found on sensitized Al-Mg alloy, with the oxide film formed on the IGC region was thicker than that on the alloy matrix due to local alkalization. Tensile stress caused dislocations near the grain boundaries, but did not change the composition of the oxide film in the region subjected to intergranular corrosion. Density-functional theory calculations suggest that tensile stress destroyed the oxide film and weakened the electronic interactions between the oxide film and the alloy matrix, fostering the propagation of intergranular corrosion.
