1. Microscopy of high temperature oxidation of iron and some stainless steels
Sammanfattning : This thesis concerns the high temperature oxidation of iron and some stainless steels. The oxide scales, as well as the subjacent metal, were investigated using a range of electron and ion microscopy techniques, including SEM, TEM, EDX and FIB. The aim was to link the microstructural observations to the oxidation mechanisms of the materials. LÄS MER

3. The Breakdown of the Protective Oxide on 11% Chromium Steel The Influence of Water Vapour and Gaseous KCl
Sammanfattning : The first part of this thesis is focused on the influence of water vapour on the oxidation of X20 steel (CrMoV 11 1). Three parameters were investigated; pH... LÄS MER
4. The Influence of Water Vapour on the Oxidation Behaviour of High-temperature Materials Microstructure investigation using analytical electron microscopy
Sammanfattning : 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.
