1. Deformation Behaviour of Near Fully Pearlitic Railway Steels During Monotonic and Cyclic Loading
Abstract : The main conclusions that could be drawn from the present work are that the deformation behaviour of fully and near fully pearlitic steels is very similar and that a combination of low temperature, prestraining and high deformation rates is critical for the performance. This was shown from microscopy studies, tensile, impact and low cycle fatigue (LCF) testing. READ MORE

2. High Temperature Corrosion of Cast Irons and Steels
Abstract : During the last decades, tougher competition and stiffer government policies have forced the automotive industry into a race for safer, cleaner and more fuel-efficient vehicles at low cost. As a consequence, exhaust systems should resist to increased working temperatures. READ MORE

4. Fatigue crack growth experiments and analyses - from small scale to large scale yielding at constant and variable amplitude loading
Abstract : This thesis is on fatigue crack growth experiments and assessments of fatigue crack growth rates. Both constant and variable amplitude loads in two different materials are considered; a nickel based super-alloy Inconel 718 and a stainless steel 316L. READ MORE

5. Influence of combined thermal and mechanical loadings on pearlitic steel microstructure in railway wheels and rails
Abstract : One of the most important aspects in railway operation is the interaction between rail and wheel. The contact patch between these two components is around the size of a small coin, and since high loads act on this small area, stresses will give rise to wear and damage in both components. READ MORE
