2. 1. On microstructure formation and mechanical properties in grey cast iron

   Author : Attila Diószegi; Preben N. Hansén; Linköpings universitet; []
   Keywords : grey iron; nucleation; primary austenite; eutectic cell; growth rate; inoculation; thermal analysis; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : A major user of cast components is the automotive industry, where the functionality of the components is related to environmental demands. Internal combustion engines are constantly being improved to emit less pollution. A vital part in this development is to increase the material properties of engine components during their life cycle.

4. 2. The mechanisms of metal expansion penetration during solidification of grey cast iron

   Author : Izudin Dugic; Preben Norgaard Hansén; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grey cast iron; solidification; solidification modelling; graphite expansion; molar volume; casting simulation; thermal analysis; thermoanalysis cup; casting temperature; inoculation; inoculant; metal expansion penetration; eutectic cell size; primary austenite; austenite grain; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The production of high quality castings requires the casting surface to be clean and free from defects. One type of defect often found is caused by metal penetration into the sand mould. READ MORE

5. 3. Metal Expansion Penetration During Solidification of Grey Cast Iron

   Author : Izudin Dugic; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grey cast iron; solidification; solidification modelling; graphite expansion; molar volume; casting simulation; thennal analysis; thermoanalysis cup; casting temperature; inoculation; inoculant; meta! expansion penetration; eutectic cell size.; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The meta! expansion penetration has been examined experimentally. The whole casting process was simulated using a commercial software, in order to investigate the solidification characteristics and the pore formation in the casting studied. READ MORE

6. 4. Effects of surfactant adjuvants on plant leaf cuticle barrier properties

   Author : Anton Fagerström; Malmö högskola; []
   Keywords : Adjuvant; Surfacant; Cuticle; Tebuconazole; Diffusion; Clivia miniata Regel leaf; Model wax; Phase diagram; Hydration; Eutectic melting; Crystalline domains; Softening; Wax film; Quartz Crystal Microbalance with dissipation QCM-D ; Differential Scanning Calorimetry DSC ; Small- and Wide-angle X-ray Diffraction SWAXD ;

   Abstract : I avhandlingen undersöks växelverkan mellan det yttersta lagret på växters blad (cutikeln), aktiva substanser, och ämnen som tillsätts för att öka bekämpningsmedlens effekt, i detta fall vissa former av tensider. Barriären som hindrar upptag av främmande ämnen i växten sitter i cutikeln. READ MORE

7. 5. Coil Design for a Mirror Based Fusion-Fission Reactor

   Author : Anders Hagnestål; Uppsala universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The SFLM Hybrid project aims to show that it is probable that a fusion-fission reactor can be constructed with a single-cell minimum B mirror machine as a neutron source. In this licentiate thesis, theoretical work has been done with the magnetic coil system of such a device and also with the overall concept. READ MORE
