Abstract

High temperature microscopy during oxidation of austenitic stainless steels shows that an increased rate of oxidation is found in a narrow zone along grain boundaries where chromium carbides have been precipitated. This lends support to the chromium-depletion theory of intercrystalline corrosion of these steels. Approximate solution of the appropriate diffusion problem shows good agreement with the experimental results.
