This work compared and analyzed the effects of the top-hat beam, Gaussian beam, and two-step method (first Gaussian beam and then top-hat beam) treatment on the corrosion behavior of joint surfaces. Activation dissolution behavior without the passive region was still found in the thick oxide scale's potentiodynamic polarization curves, which had not been removed after the top-hat beam irradiation; After Gaussian beam irradiation, the oxide scale in various local rejoins was effectively removed and passivation zones appeared. Still, the outer edge of the pulse crater with poor protection tended to corrode preferentially; By using a two-step method, first cleaned with a Gaussian beam, and then irradiated with a top-hat beam, a smooth silver-white surface with the highest pitting potential, the largest impedance, and shallow disc-shaped pit morphology can be obtained.

X65 is one of the most commonly used steel grades for offshore oil and gas pipelines. While transporting of high-pressure hydrogen is efficient and economical, harsh natural environments, such as the continuous seawater fluctuation, can cause cyclic loading on the pipeline. Therefore, the effect of hydrogen and fatigue loading on X65 pipeline steel cannot be ignored. This study aims to explore the effects of hydrogen and air environments on crack initiation and propagation. Initially, tests on fatigue life and crack growth rate are performed in H<sub>2</sub>, in addition, scanning electron microscopy and electron backscatter diffraction analyses are conducted on the specimens. Results, indicate that crack initiation is influenced by the microstructure of X65 pipeline steel with inclusions acting as the source of crack initiation, and pearlite affecting the trend of crack propagation. Hydrogen exposure decreases the fatigue life in comparison with that in air by 85.5 % and increases the crack growth rate in comparison with that in air by approximately 20 times. In the air environment the distance between the stress-concentration region and the crack tip is almost equal to the size of two grains. In H<sub>2</sub>, the cracks deflect because of the rapid growth, and the deflected cracks divide the stress concentration area. This study provides insights into the effects of hydrogen and microstructure on the fatigue properties of X65 pipeline steel, offering a theoretical basis for future studies under different conditions.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"249 ","pages":"Article 112867"},"PeriodicalIF":7.4,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632004","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}

Different grain boundary distributions were obtained by austenitizing the steel at 1050°C and 950°C, respectively. The decrease in austenitization temperature refines the prior austenite grain, and leads to a higher density of prior austenite grain boundaries (PAGBs) and high-angle packet boundaries (HAPBs), while showing a lower density of block boundaries (BBs). PAGBs and HAPBs, due to their high overall misorientation angle (OMA), possess strong hydrogen-trapping capabilities. Owing to the high specific misorientation angles between {110} slip planes ({110}-SMA) of the adjacent sub-volumes, these boundaries significantly impede the movement of dislocation carrying hydrogen atoms, thereby facilitating the hydrogen enrichment at these boundaries. As a result, a higher density of PAGBs and HAPBs means a reduced hydrogen concentration per unit boundary area, which leads to a decreased susceptibility to hydrogen embrittlement. On the other hand, BBs exhibit high OMA but low {110}-SMA. Therefore, they do not impede dislocation movement significantly. Meanwhile, the majority of BBs are Σ3 boundaries, which have weak hydrogen-trapping capacity and serve as rapid diffusion channels for hydrogen. As a result, hydrogen atoms do not accumulate at Σ3 boundaries but rather accumulate at other boundaries in their vicinity. This work provides a new insight into the effect of different types of grain boundaries on hydrogen diffusion and hydrogen trapping efficacy and offers an approach for grain boundary design to alleviate hydrogen embrittlement in bainitic/martensitic steels.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"249 ","pages":"Article 112866"},"PeriodicalIF":7.4,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143628323","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}

Results reveal that the Cr/Mo ratio exhibits different effects on the corrosion resistance of the Fe-based MGs at different potentials. At low potential, the passive current density decreases gradually with the increment of Cr/Mo ratio. This is related to the enrichment of Cr oxides and the reduction of defects densities in the passive film, which inhibit the diffusion of Cl<sup>−</sup> and the dissolution of the film. Interestingly, at high potential, as the Cr/Mo ratio increases, the corrosion property of the Fe-based MGs enhances initially and then deteriorates, and Cr<sub>10</sub>Mo<sub>5</sub> alloy demonstrates the best corrosion resistance. This is because at the appropriate Cr/Mo ratio, the potential can encourage the accumulation of Mo in passive films while also promote film thickening. This process enhances the electronic work function of the passive film, which contributes to the improved corrosion resistance.
