1. Studies of Material Properties using Ab Initio and Classical Molecular Dynamics
Sammanfattning : In this thesis, material properties have been examined under extreme conditions in computer-based calculations.The research on iron (Fe), nickel (Ni), and ferropericlase (Mg1-xFexO) are not only important for our understanding of the Earth, but also for an improved knowledge of these materials per se.

2. Inclusion Motion under a Swirl Flow in the Continuous Casting Process and Wire Feeding in the Induction Furnace
Sammanfattning : The thesis includes the studies of two phenomena related to continuous casting. One subject is the inclusion motion in the submerged entry nozzle (SEN) and mold when using a swirl flow. The swirl flow is generated in a SEN by using an electromagnetic swirl flow generator (EMSFG). LÄS MER
3. Electron beam melting of Alloy 718 : Influence of process parameters on the microstructure
Sammanfattning : Additive manufacturing (AM) is the name given to the technology of building 3D parts by adding layer-by-layer of materials, including metals, plastics, concrete, etc. Of the different types of AM techniques, electron beam melting (EBM), as a powder bed fusion technology, has been used in this study.

4. Process Development for Electron Beam Melting of 316LN Stainless Steel
Sammanfattning : Additive manufacturing (AM) is a technology that inverts the procedure of traditional machining. Instead of starting with a billet of material and removing unwanted parts, the AM manufacturing process starts with an empty workspace and proceeds to fill this workspace with material where it is desired, often in a layer-by-layer fashion.

5. Sedimentology and Geomorphology of Glacial Landforms in Southern Sweden : Studying the Landscape of a Melting Ice Sheet
Sammanfattning : Ice sheets are disintegrating due to global warming. One factor controlling ice-sheet behavior is the processes active beneath the ice sheet. In particular, processes connected to glacial meltwater drainage are essential to understand ice-sheets behavior in a warming climate. LÄS MER
