6. Processing Methods for Reaching Full Density Powder Metallurgical Materials
Abstract : Powder metallurgy (PM) is one of the most cost effective methods for manufacturing structural components with complex shapes. Utilisation of the metal powder to shape the components allows to minimise material waste and increase energy efficiency. READ MORE

8. On Surface Characteristics and Microstructural Development of Soft Magnetic Composite Powder and Components
Abstract : Soft Magnetic Composite (SMC) products manufactured by traditional Powder Metallurgical (PM) techniques, are strong candidate materials for electromagnetic applications. Their advantages are based on cost and energy efficient production methods, shape complexity realization and uniquely uniform and isotropic three dimensional (3D) magnetic properties. READ MORE

9. Net-Shape Consolidation of Water-Atomised and Gas-Atomised Steel Powder Towards Full Density
Abstract : Powder metallurgy (PM) provides resource- and cost-efficient routes to create near-net shape products compared to conventional metal fabrication techniques. To improve the mechanical performance of PM steels, it is a prerequisite to enhance the density of the material. READ MORE

10. Galling of high strength steels and stainless steels in sheet metal forming as evaluated using pin-on-disc testing
Abstract : The thesis focuses on the problem galling in sheet metal forming operations. Galling occurs when sheet metal transfers from the sheet surface onto the tool surface and causes surface damages to following sheets in the forming operation. When this happens the tool must be replaced causing production stops and additional expenses. READ MORE
