  4. 2. The Influence of Water Vapour on the Oxidation Behaviour of High-temperature Materials Microstructure investigation using analytical electron microscopy

    Author : Jun Eu Tang; Chalmers tekniska högskola; []

    Abstract : This thesis covers the analytical electron microscopy work carried out on samples exposed to high-temperature oxidation in O2 atmospheres with the intention of investigating the effect of oxygen and water vapour. SEM/EDS, TEM/EDS and diffraction techniques, complemented by FIB precision milling, were employed to characterise the formed oxide scales as well as the material directly under the scale in order to understand the mechanisms that influence the corrosion process.
