This study investigates hydrogen trapping behavior and HE susceptibility in a quenched and tempered high-carbon steel by means of thermal desorption spectroscopy (TDS), hydrogen microprinting technique (HMT), and slow strain rate tensile (SSRT) tests. Results demonstrate that dislocations act as the primary reversible hydrogen trapping sites, and hydrogen uptake decreases with the decrease of dislocation density from 3.26 × 10<sup>12</sup> cm<sup>−2</sup> in the as-quenched specimen to 4.74 × 10<sup>8</sup> cm<sup>−2</sup> in the specimen tempered at 600 ℃. Cementite/matrix interfaces act as irreversible hydrogen trapping sites, where hydrogen adsorption is governed by heterogeneous strain fields near the interfaces. SSRT results reveal that the specimen tempered at 540 ℃ exhibits high HE susceptibility, with elongation decreasing from 8.9 % to 3.6 % after hydrogen charging. In contrast, the specimen tempered at 600 ℃ retains superior ductility under identical charging conditions, with elongation decreasing from 15.4 % to 12.9 %. HE susceptibility of the experimental steel shows an exponential dependence on hydrogen content, with the fracture mode transitions driven by synergistic hydrogen-enhanced localized plasticity (HELP) and hydrogen-enhanced decohesion (HEDE) mechanisms.

In this study, through integrated experimental efforts and state-of-the-art characterization techniques, the fatigue performance and relevant enhancement mechanisms of TBC/SX systems under representative conditions (520°C–900 °C and 600°C–980 °C) were comprehensively investigated. Results demonstrated that the TMF lifespan of SXs was substantially prolonged under all conditions with TBC application, exhibiting distinct temperature dependence, and primarily extending lifespan by prolonging the crack propagation stage. The exceptional oxidation resistance of the TBC layer played a crucial role in performance improvement by altering crack-front plasticity and mitigating oxidation-driven shear strain. Furthermore, the reduced coefficient of thermal expansion (CTE) mismatch between coating and substrate due to γ'-to-γ transformation, the enhanced capacity to release thermal stress resulting from α-Cr dissolution, and the uniform deformation across microstructures facilitated by the cross-slip of screw dislocations were considered as the main contributors to the more pronounced performance enhancement under high-temperature conditions.

Although widely reported, the mechanism driving this transformation remains under debate. This study re-examines ferritization as a discontinuous reaction via a migrating liquid film and proposes a thermodynamically consistent model for the initiation and propagation of the dissolution front. The proposed mechanism is supported by experiments at 500–550°C, literature evidence, and diffusion calculations. Under low oxygen conditions, Cr transport through liquid Pb channels is identified as the rate-limiting step, setting the theoretical corrosion rate in stagnant environments. High-speed erosion-corrosion tests show enhanced corrosion rates, driven by erosion-limited channel lengths that locally boost mass transport. In contrast, under moderate oxygen concentrations relevant for lead-cooled fast reactor (LFR) operation, the rate-limiting step shifts to metal transport across a nanometer-scale amorphous oxide layer at the reaction front. Other Ni-containing austenitic steels, including alumina-forming austenitic (AFA) alloys and Ni-based high-entropy alloys (HEAs) can also be susceptible to discontinuous reactions under direct contact with liquid Pb-based alloys, lacking the self-healing oxide protection as observed in alumina-forming ferritic steels.
