21. Thermal Stability and Mechanical Properties of Bainitic Steel
Abstract : For material design it is important to understand and establish the relations between the processing of the steel, the resulting microstructure and how that correlate to the properties of the steel. The main focus of this thesis has been to increase this knowledge for low alloy bainitic steels with medium to high carbon content. READ MORE

22. Standing with and without vibration in children with severe cerebral palsy
Abstract : Children with severe cerebral palsy (CP) risk fragile bones, fractures and hip dislocation due to disuse. A standing shell allows these children weight bearing in an upright position. Recommended standing time is one to two hours/day but evaluations are lacking. READ MORE

23. Evolution of WC-Co cemented carbide microstructure during creep testing
Abstract : The aim of this work is to understand the mechanisms behind the plastic deformation of WC-Co based cemented carbides. The microstructures of two materials have been investigated before and after creep deformation using quantitative microscopy, atom probe tomography, and transmission electron microscopy. READ MORE

25. Modeling the Microstructural Evolution during Hot Deformation of Microalloyed Steels
Abstract : This thesis contains the development of a physically-based model describing the microstructural evolution during hot deformation of microalloyed steels. The work is mainly focused on the recrystallization kinetics. During hot rolling, the repeated deformation and recrystallization provides progressively refined recrystallized grains. READ MORE
