The iron contentIron content in Ni–Cr–xFe (x = 0–9 at.%) alloys strongly affected the properties of oxide films Oxide filmformed in a simulated PWR primary water environment at 310 °C. Increasing the iron content in the alloys increased the amount of iron-bearing polyhedral spinel oxide particles in the outer oxide layer and facilitated the local oxidation penetrationLocal oxidation penetration into the alloy matrix from the chromium-rich inner oxide layer. The local oxidation penetration was caused by the pile-up of the cation vacancies.
