| Abstract Scope |
The effect of stress on the corrosion susceptibility of 316H stainless steel was studied using a four-point bending device to create various stresses and shear stresses on a single specimen. Both the four-point bending device and the stressed specimen were submerged in FLiNaK at 700°C for 100 hours. Scanning electron microscopy was used to quantitatively determine the cracking density and cracking penetration depth, as revealed from the polished cross-section. For regions of great interest, a focused ion beam is used to prepare specimens, followed by transmission electron microscopy and EDS mapping. Corrosion over a position matrix was studied. The location was varied to correlate with local tensile and compressive stresses through finite element analysis. Hence, the effect of stress on corrosion susceptibility was established. This information is useful for comprehensively analyzing the corrosion behavior of MSR structural components under realistic operational conditions. |
