However, due to the presence of numerous defects and deleterious phases in wrought 316L SS, it is prone to corrosion in MSA, which may lead to energy inefficiency and compromise the purity of lead during the recycling process. To address corrosion-related risks and economic impacts, this study investigated the corrosion behavior of 316L SS fabricated via laser powder bed fusion (LPBF) in simulated SLP solutions, with comparative analysis against conventional wrought counterparts. Potentiodynamic polarization curves showed that LPBF-316L SS had a more negative corrosion potential, lower corrosion current, and better pitting corrosion resistance. LPBF-316L SS can sustain stability in the simulated solution for a prolonged duration. The growth mechanism of the LPBF-316LSS passive film was elucidated through the application of Mott–Schottky (M–S) tests and point defect model (PDM). During LPBF process, the uniquely formed cellular microstructures, uneven elemental distribution, and fewer detrimental secondary phases collectively contribute to the formation of a denser passive film and accelerated growth kinetics for LPBF-316L SS in the simulated solution.</p></div>","PeriodicalId":605,"journal":{"name":"JOM","volume":"78 8","pages":"7594 - 7608"},"PeriodicalIF":2.3,"publicationDate":"2026-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148553257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These materials with different heat treatments and chemical compositions were irradiated in the BR2 reactor at 290°C in the low-neutron dose range where post-irradiation effects are the most significant in terms of damage rate. Accurate neutron dosimetry allowed the individual determination of the precise dpa dose of each irradiated specimen. Static tensile tests were performed at room temperature and 300°C before and after irradiation to assess the radiation-induced hardening. The results suggest that the replacement of Mo by W seems to significantly affect the work-hardening capacity of the steel, promoting premature plastic flow localization upon irradiation. Second, the three steels, E97, F82H, and EM10, exhibit a unique <span>(Delta sigma_{gamma}(Phi_{text{dpa}}))</span> trend curve, while the T91-trend curve is clearly higher, in particular in the early stage of irradiation, below ~ 0.2 dpa.

Contrary to what is reported in the literature for low-temperature irradiation, the true stress–true strain curves do not superimpose when shifted with respect to the unirradiated flow curve, indicating that the post-yield mechanisms are different.
