2. Thin film growth and characterization of Ti-Si-C MAX-phases
Abstract : This thesis describes the growth of Ti-Si-C MAX-phases on A12O3(0001) and MgO(111) substrates with the emphasis on epitaxial Ti3SiC2 thin films by means of DC magnetron sputtering. Ti3SiC2, Ti4SiC3 as well as the two intergrown structures Ti5Si2C3 and Ti7Si2C5 were grown using sputtering from three individual elemental targets of Ti, Si, and C, respectively. READ MORE

3. Spark Plasma Sintered 3Y-TZP/CNT composites
Abstract : Composites of 3 mol% yttria-doped tetragonal zirconia (3Y-TZP) reinforced with multiwalled carbon nanotubes (MWCNT) up to 2 wt% have been produced using spark plasma sintering (SPS). The theoretical densities of the studied composites were found to be between 99.4 and 97.4 %. READ MORE

4. Relaxation and nanomechanical studies of the vickers residual stress field in glass
Abstract : The Vickers residual stress field (VRSF) in soda-lime glass results from the elastic-plastic contact event that takes place when a Vickers diamond pyramid is loaded onto the surface of the material in an indentation cycle. The importance of elastic-plastic indentation lies in the contact damage that it gives rise to in the surface of the glass. READ MORE

5. Determination of residual stresses and mechanical properties using neutron, X-ray diffraction, micro- and nanoindentation techniques
Abstract : The existence of residual stresses in engineering materials can significantly affect subsequent lifetime by augmenting or impeding failure. Consequently, for an accurate assessment of engineering lifetimes, there is a need to quantify residual stresses. READ MORE
