2. 16. Innovating Recycling of End-of-Life Cars

   Author : Magnus Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; End-of-Life; Scarce Metal; Material Flow Analysis; Vehicle; Technological Innovation System; Car; Critical Material; Recycling;

   Abstract : There are currently a billion cars in use worldwide, and car design trends point at increasing variety in material utilisation. Cars today contain several types of steel and aluminium, an assortment of textiles and padding materials, and an increasing amount of polymers and scarce metals. READ MORE

4. 17. Optical interconnects and high frequency electronic packaging : SBU-materials, material characterization, LAP- & microprocessing

   Author : Steffen Uhlig; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical interconnects; overview opto coupling components; overview planar waveguide amplifiers; large area panel processing; polymer waveguides; multilayer thin film technology; ORMOCER®; sequential build up; permittivity; dielectric loss;

   Abstract : The main objective of this thesis is to discuss and demonstrate optical interconnect technologies. These can be used to enhance the data throughput capacity of future printed circuit boards and backplanes, i.e. exchange Copper conductors with light conductors. READ MORE

5. 18. Cavitation Erosion Mechanisms in Cast Irons

   Author : Marcio Freitas de Abreu; Stefan Jonsson; Jessica Elfsberg; Matevz Dular; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : The research presented in this thesis investigated the mechanisms by which cavitation erosion damage develops in lamellar graphite iron (LGI) and austempered ductile irons (ADIs). This has been achieved by image sequences of surface erosion on test samples in tandem with weight change measurements. READ MORE

6. 19. On Surface Characteristics and Microstructural Development of Soft Magnetic Composite Powder and Components

   Author : Christos Oikonomou; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; X-ray photoelectron spectroscopy; compaction; annealing; X-ray diffraction; soft magnetic composites; high resolution scanning electron microscopy; surface layers; magnetic testing; powder metallurgy; depth profiling; electron backscatter diffraction; focused ion beam; thickness determination; energy dispersive X-ray spectroscopy; microstructure;

   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

7. 20. Interaction between pellet properties and blast furnace operation

   Author : Ulrika Leimalm; Gabriella Tranell; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : The raw material properties of iron-bearing material and coke have a significant impact on the blast furnace (BF) process. The raw materials are designed and chosen to achieve smooth BF operation but the operational parameters can be simultaneously modified to meet properties of selected raw materials. As the pre-set process conditions change, e. READ MORE
