What is Multi-modal analysis of oxidation on Fe-Cr-Ni austenitic stainless steel 304 exposed to beyond-design basis temperatures about?
Stainless Steel 304 is being investigated for accident tolerant claddings. In this investigation, we use multi-modal characterization to evaluate oxidation under laboratory air versus 100% steam at 1200 oC for 2 h. Air oxidation features Fe(NiMn)O 4 , Fe 3 O 4 , Fe (3-x) Cr x O 4 , and Cr 2 O 3 . Steam oxidation produces a dual layer, containing Fe 2 O 3enriched porous outer layer and sub-surface matrix of Fe 3 O 4 /Fe (3-x) Cr x O 4 with SiO 2 /Fe (3-x) Si x O 4 . From these findings, we postulate the oxidation mechanism. Arrangement of oxidation products in air corroborates with anticipated diffusion behavior, except Cr 2 O 3. However, arrangement in steam deviates due to presumably intergranular interactions with H 2 O, resulting in the sub-surface matrix.
