2. Microstructure and Wear of CVD Coatings used in Metal Cutting Applications
Abstract : This thesis is concerned with the microstructural characterisation of wear resistant Al2O3 and Ti(C,N)coatings produced by chemical vapour deposition on cemented carbide cutting tools. The investigation focuses on the effect of deposition conditions on the microstructure and the microstructural evolution of the coatings during heat-treatments and metal cutting. READ MORE

3. Metastable Alumina from Theory: Bulk, Surface, and Growth of κ-Al2O3
Abstract : Aluminas are materials of high technological importance that show a fascinating structural flexibility, with a large amount of different phases (alpha, gamma, eta, delta, kappa, chi, ...) and phase transitions at relatively high temperatures. READ MORE

4. Alumina (Al2O3) and Oxidation of Aluminium. A First-Principles Study
Abstract : Aluminum oxides and oxidation mechanisms are topics for extensive research. One good reason for this is their wide range of applications. For instance, the .alfa. READ MORE

5. Computer Simulations in Materials Physics: Time-scales and Accuracy
Abstract : Computer simulations are expected to play an increasingly important role within materials physics in the future. Owing to a combination of accurate physical approximations, improved implementations of these approximations, and the exponentially increasing power of computers, problems can now be solved on length and time-scales which were unimaginable only a decade ago.
