✦ Synopsis

This study aims to an experimental and theoretical description of three different corrosion phenomena of steels during high-temperature exposure: (i) the effect of vanadium content during oxidation of tool steels, (ii) the grain size effect during oxidation of low-Cr boiler steels, and (iii) the carburization of austenitic steels. The experimental part was carried out by means of thermogravimetric measurements and scanning electron microscopy observations. Computational thermodynamics investigations were carried out by performing complex equilibrium calculations of the Fe-Cr-V-W-Mo-O-C system using the commercial software FactSage. The kinetics of oxidation and carburization processes were accounted for by solving the diffusion differential equation numerically (finitedifference method) taking the material's microstructure into consideration, by distinguishing between precipitation along the grain boundaries and within the grain interior as well as incorporating local thermodynamic equilibrium by means of the subroutine ChemApp, which works according to Gibbs energy minimization criteria.

## Abstract It is essential for materials used at high‐temperatures in corrosive atmosphere to maintain their specific properties, such as good creep resistance, long fatigue life and sufficient high‐temperature corrosion resistance. Usually, the corrosion resistance results from the formation of a
