Nonetheless, weld joints often emerge as critical positions limiting the steel service life. Research on the service performances of weld joints in novel F/M steels enriched with Cr, Si, and especially rare earth elements remains lacking. Here, by studying a rare earth F/M steel and its weld joints, we systematically evaluated the corrosion resistance and degradation mechanism of laser-weld joints of the steels in liquid lead-bismuth eutectic alloy. Atomic-scale structural and chemical characterizations revealed that the welding process leads to a loss of solute Y and hence hinders the formation of the crucial Cr<sub>2</sub>O<sub>3</sub>-rich anti-oxidation layer. Without the protection, oxygen diffusion zone develops in the coarse columnar crystals in the weldment, which further undermines the density of the oxide scale.

This study introduces an inner notched specimen that more accurately simulates wall thickness reduction at defect sites. The impact of the notch on the material’s mechanical properties was assessed through slow strain rate tensile tests. The hydrogen diffusion process was also analyzed using gaseous hydrogen permeation tests, which quantified changes in hydrogen flux due to the presence of the notch. Furthermore, microstructural characterization near the notch was performed using Electron Backscatter Diffraction (EBSD) to investigate the causes of the observed differences in test results induced by the defect. The findings indicate that susceptibility to hydrogen embrittlement at standard notches was lower than at inner notches with the same relative depth. Consequently, the critical safe hydrogen blending ratio determined from the standard notch may be conservative and should be reconsidered alongside results from the inner notch in practical applications. Notches positioned on the hydrogen-contacting side of the specimen increased the contact area between hydrogen and the metal surface, facilitating the dissociative adsorption of hydrogen molecules. This enhanced hydrogen adsorption and its subsequent penetration into the steel surface. In contrast, outer notches provided a different diffusion path for hydrogen atoms, with a greater decay in hydrogen concentration along the diffusion direction compared to smooth specimens. This led to fewer hydrogen atoms accumulating at the notch on the hydrogen-measuring side.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"249 ","pages":"Article 112839"},"PeriodicalIF":7.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143551110","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}

The microstructure transforms from lamellar structure to basketweave structure, which the content of the β phase and the ratio of β/α phase boundary are increased greatly. With the increasement of V quality fraction, the passivate film becomes denser, thicker and more stable, which is because the increasement of the ratio of α/β phase boundary makes the passivate film easier to form.

Especially, the V quality fraction ≥ 4 wt.%, the corrosion resistance is greatly increased.

In this study, X-ray diffraction topography (XRT) and scanning electron microscopy (SEM) were employed to analyze the environmental stress-induced formation and evolution of the micro-defects in a deteriorating organic coating. Electrochemical impedance spectroscopy (EIS) was used to investigate how these stress-induced micro-defects affect coating capacitance. The results showed that environmental stresses not only significantly alter the surface morphology of coated specimens but also promote the initiation and growth of both new and pre-existing micro-defects, leading to changes in their distribution. Additionally, applied stresses were found to favor the formation of non-spherical micro-defects more effectively than corrosion stress. Changes in the number and distribution of micro-defects directly influenced coating capacitance, which, in turn, impacted its protective performance. Overall, this study underscores the critical role of environmental stresses in initiating and propagating micro-defects within organic coating protective systems.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"249 ","pages":"Article 112815"},"PeriodicalIF":7.4,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143518962","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}
