## Abstract The behavior of oxide scales on Fe‐20Cr alloy was investigated in constant load at 1173 K in air. The objective was to understand the effect of mechanical loading on the deformation of oxide scales. It was carried out mainly by comparison of surface morphologies of oxidized specimens ob
## Abstract During the oxidation, in laboratory air, of thin foils of Fe–20Cr–5Al based alloys, voids were formed in the substrate beneath the outer protective alumina scale after times varying from 50 h at 900 °C to 10 min at 1200 °C. Once the substrate aluminium level had dropped below a critical
## Abstract Alloys for high temperature applications rely on a protective oxide layer formed by selective oxidation. In Fe20Cr5Al type alloys the useful lifetime is governed by the depletion of aluminium by oxidation down to a critical aluminium content. Following spallation of the oxide scale the
