The NaCl-KCl-UCl<sub>x</sub> salts were prepared through the electrochemical oxidation of uranium rods. The ratio of UCl<sub>3</sub> and UCl<sub>4</sub> in the UCl<sub>x</sub> salts was determined by X-ray absorption near-edge structure (XANES) analysis. The presence of UCl<sub>4</sub> was further confirmed by the accelerated corrosion behaviors depending on the UCl<sub>x</sub> concentration. After exposing stainless steel 316 to NaCl-KCl-UCl<sub>x</sub> salts at 750 °C for 100 h using alumina, boron nitride, and glassy carbon crucibles, UO<sub>2</sub> was formed on the surface in various forms, such as layers and/or particles. Additional corrosion experiments with NaCl-KCl-UCl<sub>x</sub>-BaO salts were conducted to investigate the UO<sub>2</sub> formation mechanisms. Results indicate that UO<sub>2</sub> formation occurs via two pathways: reactions between salts and stainless steel 316 or deposition of UO<sub>2</sub> formed in the salts. Regardless of how it forms, it is evident that UCl<sub>3</sub> and UCl<sub>4</sub> can produce UO<sub>2</sub> through reactions with oxygen-related compounds (oxides, O<sup>2-</sup>, O<sub>2</sub>). The formation of UO<sub>2</sub> can mitigate chromium depletion, but the precipitation of UO<sub>2</sub> may lead to additional challenges. This study suggests the importance of both crucible selections for U-containing molten salt corrosion experiments and the consideration of UO<sub>2</sub> formation in molten salt reactor environments.</div></div>","PeriodicalId":290,"journal":{"name":"Corrosion Science","volume":"252 ","pages":"Article 112979"},"PeriodicalIF":7.4,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143873495","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}

In this study, grain refinement and solution heat treatment are applied in in-situ TiB<sub>2</sub> nanoparticles modified AMed AlCuMg alloy to overcome these limitations. The resultant composites exhibited a remarkable strength-ductility product of 4619 MPa% (85-fold improvement) with an elongation of 8.9 %, alongside a 76.7 % reduction in corrosion current density, demonstrating superior overall performance compared to previously reported aluminum alloys and composites. Detailed investigations revealed that the uniform distribution of refined grains not only enhanced grain boundary strengthening but also improved the stability of passivation films.

The complex interplay between such microstructural variations and porosity on the corrosion and stress corrosion cracking (SCC) properties of the 316L austenitic stainless steel produced using CM, laser powder bed fusion (LPBF), binder jet printing (BJP), and BJP+hot isostatic pressing (HIP) techniques were investigated and compared. The resistance of the steels to localized corrosion resistance has the following order: BJP < (BJP + HIP) ≈ CM < LPBF, while their SCC resistance ranked as BJP < LPBF ≈ CM < (BJP + HIP). BJP 316L’s lowest resistance is due to the combined effects of the high fractions of δ-ferrite, σ-phase and porosity present in it. The rapid solidification conditions prevalent during LPBF result in the refinement of the Mn-Si-O inclusions and complete elimination of the MnS inclusions. Both these features impart superior localized corrosion resistance to LPBF 316L. However, pit growth and crack propagation are facilitated by high residual strain within its microstructure, making its SCC resistance comparable to that of CM 316L. HIP after BJP led to a substantial reduction of δ-ferrite fraction and porosity. Both these factors significantly enhance the localized corrosion resistance and make the BJP+HIP 316L’s SCC resistance superior.

Results unveil that the residual strain and anisotropy grains jointly deteriorate the planar SCC initiation response, while high-density low angle grain boundaries alleviate the depth attack of short-term SCC propagation. Furthermore, the cellular structure, decorated with Cr segregation and dislocation tangles, inhibits the short-term SCC propagation by enhancing the re-passivation capacity and oxide rupture resistance at the crack tip. The other concomitant factors, such as oxide precipitates and melting pools, are considered subordinate to the SCC susceptibility.
