11. Deformation and failure of brittle rocks under compression
Sammanfattning : This thesis describes the deformation and failure of rocks under compression through a micromechanics model and laboratory studies of the Kaiser effect. It comprises an overview and seven appended papers. The deformation model is developed based on the analysis of the behaviour of microcracks. LÄS MER
12. Deformation and Fracture Behavior of Transparent Wood-Polymer Biocomposites
Sammanfattning : Transparent wood-polymer biocomposites (TWPBs) are interesting wood-based materials with a unique combination of optical transmittance and mechanical properties. The wood substrate is delignified (removal of lignin) while the wood microstructure is preserved. LÄS MER
13. Evolution of WC-Co cemented carbide microstructure during creep testing
Sammanfattning : 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. LÄS MER
14. Microstructure Development of WC-Co Based Cemented Carbides During Creep Testing
Sammanfattning : The aim of this work is to understand the mechanisms behind the plastic deformation of WC‐Co based cemented carbides. The microstructure of two series with different WC grain size was investigated before and after creep deformation using quantitative microscopy, atom probe tomography, and transmission electron microscopy.

15. Heat treatment of Al-Si-Cu-Mg casting alloys
Sammanfattning : Environmental savings can be made by increasing the use of aluminium alloys in the automotive industry as the vehicles can be made lighter. Increasing the knowledge about the heat treatment process is one task in the direction towards this goal. The aim of this work is to investigate and model the heat treatment process for Al-Si casting alloys. LÄS MER
