2. 16. Properties of Ugandan minerals and fireclay refractories

   Author : John Baptist Kirabira; Stefan Jonsson; Thomas Johansson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; kaolin; clay; Ugandan minerals; fireclay; refractory; powders characterization; beneficiation; ceramics; mullite; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : Development of products which can be produced from a country’s natural resources is very important as far as the industrialization of a nation and saving foreign exchange is concerned. Presently, industries in Uganda and the other states in the Lake Victoria region import all refractory-related-consumables, as the demand cannot be met locally. READ MORE

4. 17. Miniature Phase-Transistion Actuators

   Author : Lena Klintberg; Lars Montelius; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Abstract : Clearly, there is a need for simple, strong actuators capable of large strokes in miniaturized systems such as valves and optical shutters.The basis for this work is the microstructure technology with processing techniques adopted from the integrated circuit industry. READ MORE

5. 18. Calcium Aluminate based Cement as Dental Restorative Materials

   Author : Lars Kraft; Charles Lloyd; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

   Abstract : This thesis presents the results from the development process of a ceramic dental filling material based on calcium aluminate cement. The main focus of the work concerns dimensional changes during setting, hardening and curing and the understanding of the factors controlling the dimensional stability of the system. READ MORE

6. 19. Friction stir welding of copper canisters for nuclear waste

   Author : Therese Källgren; Rolf Sandström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Friction Stir Welding FSW ; Copper; Welding; Finite Element Method FEM ; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : The Swedish model for final disposal of nuclear fuel waste is based on copper canisters as a corrosion barrier with an inner pressure holding insert of cast iron. One of the methods to seal the copper canister is to use the Friction Stir Welding (FSW), a method invented by The Welding Institute (TWI). READ MORE

7. 20. On the shrinkage of metals and its effect in solidification processing

   Author : Anders Lagerstedt; Hasse Fredriksson; Alec Mitchell Mitchell; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; material science; mechanical engineering; metallurgy; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Abstract : The shrinkage during solidification of aluminium and iron based alloys has been studied experimentally and theoretically. The determined shrinkage behaviour has been used in theoretical evaluation of shrinkage related phenomena during solidification. Air gap formation was experimentally studied in cylindrical moulds.
