1. On the influence of imperfections on microstructure and properties of recycled Al-Si casting alloys
Sammanfattning : There are great energy savings to be made by recycling aluminium; as little as 5% of the energy needed for primary aluminium production may be required. Striving to produce high quality aluminium castings requires knowledge of microstructural imperfections, which is extra important when casting recycled aluminium that generally contains higher levels of imperfections compared to primary aluminium.

2. Casting and anodising of Al alloys- Alloy design, manufacturing process and material properties
Sammanfattning : Casting and semi-solid metal (SSM) casting are widely used to manufacture near-net-shape components of Al-Si alloys in the automotive and electronic industries. In such applications, casting components need to meet the combined requirements of good mechanical properties and corrosion and wear resistance. LÄS MER
3. Magnetic ordering and crystal structure in selected transition- metal compounds
Sammanfattning : Applications of magnetic materials are inherently related to their crystal, magnetic and electronic structures. In this thesis, experimental and theoretical methods have been focused on magnetic bulk materials from novel chemical synthesis, to X-ray diffraction for initial phase characterisation, and crystal and magnetic structure studies to explain their complex magnetic properties.

4. The effect of microstructural features, defects and surface quality on the fatigue performance in Al-Si-Mg Cast alloys
Sammanfattning : Global warming is driving industry to manufacture lighter components to reduce carbon dioxide (CO2) emissions. Promising candidates for achieving this are aluminium-silicon (Al-Si) cast alloys, which offer a high weight-to-strength ratio, excellent corrosion resistance, and good castability. LÄS MER
