Corrosion behavior of alloy 800H (Fe–21Cr–32Ni) in supercritical water
Source abstract
Abstract
Abstract The effect of testing conditions (temperature, time, and oxygen content) and material’s microstructure (the as-received and the grain boundary engineered conditions) on the corrosion behavior of alloy 800H in high-temperature pressurized water was studied using a variety of characterization techniques. Oxidation was observed as the primary corrosion behavior on the samples. Oxide exfoliation was significantly mitigated on the grain boundary engineered samples compared to the as-received ones. The oxide formation, including some “mushroom-shaped oxidation”, is predicted via a combination of thermodynamics and kinetics influenced by the preferential diffusion of specific species using short-cut diffusion paths.
