Corrosion Evolution of T91 Steel in Static Lead-Bismuth Eutectic Under an Oxidising Environment
This study investigates the corrosion mechanisms of T91 steel in static lead-bismuth eutectic under high-temperature oxidizing conditions, revealing that grain boundary attack driven by chromium and oxygen diffusion can be mitigated by a stable oxide scale, while unexpectedly forming a unique iron-enriched body-centered cubic surface layer.
