  2. 1. Warm Sheet Metal Forming with Localized In-Tool Induction Heating

    Author : Linus Larsson; Industriell Produktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; warm sheet metal forming. elevated temperature; aluminium; malgnesiurn. induction heating;

    Abstract : The increasing use of light metals and high strength steel in the automobile industry, demands for new sheet metal forming processes that can be applied successfully. In this thesis the subject of warm sheet metal forming is studied. READ MORE

  4. 2. Hydro-mechanical forming of aluminium tubes : on constitutive modelling and process design

    Author : Mikael Jansson; Larsgunnar Nilsson; Odd Sture Hopperstad; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydroforming; Aluminium Extrusions; Anisotropic material; Solid mechanics; Fastkroppsmekanik;

    Abstract : Tube hydroforming is a forming method which has several advantages. By using pressure in combination with material feeding it is possible to manufacture products with high structural integration and tight dimensional tolerances. The forming method is especially suited for aluminium alloys which have a relatively low ductility. READ MORE

  5. 3. An in situ spectro-electrochemical study of aluminium/polymer interfaces : development of ATR-FTIR and its integration with EIS for corrosion studies

    Author : Maria Öhman; Christofer Leygraf; Jan-Olov Nilsson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; : ATR-FTIR; EIS; spectro-electrochemical; interface; aluminium; polymer; Other chemistry; Övrig kemi;

    Abstract : In order to extend the applications of aluminium, organic coatings may be applied on sheet materials, for instance for corrosion protection or aesthetic surface finish purposes in the automotive and construction industries, or on foil materials in the flexible packaging industry. The most common mechanisms for deterioration and structural failure of organically coated aluminium structures are triggered by exposures to the surrounding environment. READ MORE

  6. 4. Fatigue Strength of Friction Stir Welded Joints in Aluminium

    Author : Mats Ericsson; Rolf Sandström; Ole Terje Midling; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Applied Materials Technology; friction stir welding; fatigue; mechanical properties; welding speed; softening; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : Solid state Friction stir welding (FSW) is of major interest in the welding of aluminium since it improves the joint properties. Many applications where Al-alloys are used are subject to varying load conditions, making fatigue failure a critical issue. READ MORE

  7. 5. Development and evaluation of hybrid joining for metals to polymers using friction stir welding

    Author : Wallop Ratanathavorn; Arne Melander; Stefan Hallström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloy; thermoplastic; friction stir welding; dissimilar joining; Production Engineering; Industriell produktion;

    Abstract : Combinations of different materials are increasingly used in the modern engineering structures. The driving forces of this trend are rising fuel costs, global warming, customer demands and strict emission standards. READ MORE
