1. Martensitic Transformations in Steels : A 3D Phase-field Study
Abstract : Martensite is considered to be the backbone of the high strength of many commercial steels. Martensite is formed by a rapid diffusionless phase transformation, which has been the subject of extensive research studies for more than a century. READ MORE

2. Mechanisms of Plastic Deformation of Cemented Carbide and Cermet Cutting Tools
Abstract : In this thesis, the physical mechanisms acting during plastic deformation of hardmetals used in metal cutting applications have been investigated. Microstructural and microanalytical studies have been performed on cemented carbides as well as cermet materials. READ MORE

3. PFB Air Gasification of Biomass, Investigation of Product Formation and Problematic Issues Related to Ammonia, Tar and Alkali
Abstract : Fluidised bed thermal gasification of biomass is an effective route that results in 100 % conversion of the fuel. In contrast to chemical, enzymatic or anaerobic methods of biomass treatment, the thermal conversion leaves no contaminated residue after the process. READ MORE

4. Migration from plastic food packaging during microwave heating
Abstract : Microwave heating of food has increased rapidly as a food processing technique. This increases the concern that chemicals could migrate from food packaging to food. The specific effect of microwave heating in contrast to conventional heating on overall and specific migration from common plastic food storage boxes was studied in this work. READ MORE

5. Generalised stacking fault energy and plastic deformation of austenitic stainless steels
Abstract : Austenitic stainless steels are primarily known for their exceptional corrosion resistance. They have the face centred cubic (FCC) structure which is stabilised by adding nickel to the Fe-Cr alloy. The Fe-Cr-Ni system can be further extended by adding other elements such as Mn, Mo, N, C, etc. in order to improve the properties. READ MORE
