21. Multiscale Modeling of Interfaces
Abstract : Understanding strength and stability of interfaces between dissimilar materials or phases is a highly active field of contemporary materials research. Knowledge of interface structure and energetics is important for modeling of complex materials both on a mechanical and thermodynamical level as well as for many functional properties. READ MORE

22. Atom Probe Field Ion Microscopy of Surface Zones, Coatings and Interfaces
Abstract : This thesis is focused on developingmethods for high resolution microanalysis of coatings on a substrate, andsurface zones of a bulk sample using atom probe field ion microscopy,APFIM. The APFIM technique is described and some examples of its applications to semiconductors,cemented carbides and intermetallic compounds are given. READ MORE

23. Defects in Austenitic Steels and Hard Metals - A DFT-based Study
Abstract : Materials are never 100% pure due to the limitation of purification method or manufacturing process. Nor are they perfect, especially under deformation. The present work aims to explore different roles played by the defects in austenitic steels and hard metals. READ MORE

24. Phase field modeling of precipitation reactions in miscibility gap systems
Abstract : As a backbone to the cutting tools and rock drilling industry, cemented carbides have been used widely due to their high hardness and wear resistance. Most commercially used cemented carbides contain a hard phase made of Tungsten carbide (WC) and a binder phase which is generally ductile. READ MORE

25. Atomic-scale investigation of interfacial structures in WC-Co at finite temperatures
Abstract : WC-Co cemented carbides combine superb hardness with high toughness making them ideal for usage in high-speed machining of steels and in wear resistance tools. These excellent mechanical properties are to a large extent dependent on the microstructure and thus the interfacial properties of the material. READ MORE
