| 英文摘要 | In this paper, corrosion performance of 304N austenitic stainless steel with 0.17 wt.% nitrogen was studied in flowing oxygen-saturated lead bismuth eutectic (LBE) at 400 degrees C. Perpendicular flow pattern was introduced to steel surface, on which various corrosion behaviors, i.e. oxidation, erosion, and dissolution, were simultaneously detected even at a low fluid rate of similar to 1 m/s after 1000 h. This allowed an investigation into their synergistic effects. Besides, degradation in chemical compositions and mechanical properties was profoundly identified within steel subsurface by means of multi-scale characterization. Role of subsurface degradation in different corrosion failure modes was then elucidated. With regard to breakaway oxidation, an interesting mechanism was proposed for this essential feature of austenitic steels. Plastic deformation microstructure within perpendicularly eroded austenitic steel subsurface, confirmed in other flowing corrosive media, was revealed in liquid LBE flow for the first time and explained in terms of stacking fault energy. Crack across the degraded steel subsurface was proven to be responsible for LBE penetration and selective dissolution attack on steel matrix. |
