1. Development of a Morphology-based Analysis Framework for Asphalt Pavements
Sammanfattning : The morphology of asphalt mixtures plays a vital role in their properties and behaviour. The work in this thesis is aimed at developing a fundamental understanding of the effect of the asphalt morphology on the strength properties and deformation mechanisms for development of morphology-based analysis framework for long-term response prediction.

2. An Operational View on Foaming and Slopping Control in Top-blown BOS Vessels
Sammanfattning : Slag formation plays a decisive role in all steelmaking processes. In top-blowing Basic Oxygen Steelmaking (BOS) i.e., in the LD process, an emulsion consisting of liquid slag, dispersed metal droplets, undissolved particles and solid precipitates will, together with process gases, form an expanding foam.

3. Failure mechanisms in APS and SPS thermal barrier coatings during cyclic oxidation and hot corrosion
Sammanfattning : Thermal Barrier Coatings (TBCs) are advanced material systems that are being used in the hot sections of gas turbines such as combustor, turbine blades, and vanes. The top ceramic coating in TBCs provides insulation against the hot gases and the intermediate metallic bond coat provides oxidation and corrosion resistance to the underlying turbine components.

4. Additive metallurgy - Thermal influences on structure and properties of stainless steel 316L
Sammanfattning : Additive manufacturing (AM) as a manufacturing process has, in recent years, become widely accepted as capable of manufacturing parts that will be used in end products. In this thesis, stainless steel grade 316L parts are manufactured using two different powder bed fusion techniques, selective laser melting (SLM) and electron beam melting (EBM). LÄS MER
5. Reliability-based Design Procedure for Flexible Pavements
Sammanfattning : Load induced top-down fatigue cracking has been recognized recently as a major distress phenomenon in asphalt pavements. This failure mode has been observed in many parts of the world, and in some regions, it was found to be more prevalent and a primary cause of pavements failure. LÄS MER
