Abstract

Annealed and abraded specimens of Fe containing 0–26% Cr were oxidized in water vapour-argon at 600°C and the oxidation measured by the gain in weight. Cold work improved the oxidation resistance of high-Cr alloys by suppressing internal oxidation. With low-Cr alloys, annealed and abraded specimens both show internal oxidation and there is no beneficial effect of cold work; a short-term deleterious effect is observed. The oxidation of unalloyed Fe in water vapour was not affected by cold work.
