2. Experimental Studies of Deformation Structures in Stainless Steels using EBSD
Abstract : In this thesis, the focus has been the study of deformation structures in stainless steels by using electron backscatter diffraction (EBSD). Via increased knowledge of the evolution of the substructure during deformation, the design and control of the manufacturing process can be improved. READ MORE

3. Significance of grain boundaries for transport phenomena in graphene and proton-conducting barium zirconate
Abstract : Grain boundaries can have a significant influence on the properties of polycrystalline materials. When determining the type and extent of this influence it is frequently useful to employ computational methods such as density functional theory and molecular dynamics, which can provide models of the grain boundary structure at the atomistic level.

4. Atomic-scale modelling of interfaces in cemented carbides: wetting and strength
Abstract : Cemented carbides are composite materials of great technological and industrial importance. They have a unique combination of hardness and toughness and are therefore used widely as tool materials in applications where both high hardness and toughness are demanded. These applications include among others: mining, turning, cutting and milling. READ MORE

5. Atomistic modeling of interfaces in WC-Co cemented carbides
Abstract : Grain and phase boundaries are crucial in understanding the properties of real materials. In this thesis, interfaces in WC–Co cemented carbide are modeled atomistically using density functional theory (DFT) and analytic interatomic potentials. READ MORE
