摘要：One of the most intriguing methods of mitigating the hydrogen embrittlement of steels entails nanoprecipitates that can trap H from enriching at vulnerable locations. However, controversial findings have been reported on whether the incoherent NbC precipitates trap hydrogen. Here, by using in-situ scanning Kelvin probe force microscopy (SKPFM), we reveal the dynamic interaction of H with the border area of incoherent NbC nanoprecipitates in steel. Results indicate that the interaction between H flux and the interfaces varies amongst different precipitates, implying that H-trapping behaviours of incoherent NbC precipitates could be intrinsically diverse. Potential origins underlying the distinct behaviours are analyzed. 漏 2024
