  1. 1. Casting and anodising of Al alloys- Alloy design, manufacturing process and material properties

    Författare :Baiwei Zhu; Caterina Zanella; Rajan Ambat; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium; Semi-solid casting; Anodising; Gjutning av aluminium; semi-solid gjutning; anodisering; komponent; gjutlegering; kisel; järn;

    Sammanfattning : Casting and semi-solid metal (SSM) casting are widely used to manufacture near-net-shape components of Al-Si alloys in the automotive and electronic industries. In such applications, casting components need to meet the combined requirements of good mechanical properties and corrosion and wear resistance. LÄS MER

  3. 2. On the influence of imperfections on microstructure and properties of recycled Al-Si casting alloys

    Författare :Anton Bjurenstedt; Salem Seifeddine; Anders E.W. Jarfors; Arne Dahle; Johan Moverare; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Imperfections; Recycled Al-Si alloys; Fe-rich intermetallics; Melt quality; Fractography; Defekter; Återvunna Al-Si legeringar; Fe-rika intermetaller; Smältakvalité; Fraktografi;

    Sammanfattning : There are great energy savings to be made by recycling aluminium; as little as 5% of the energy needed for primary aluminium production may be required. Striving to produce high quality aluminium castings requires knowledge of microstructural imperfections, which is extra important when casting recycled aluminium that generally contains higher levels of imperfections compared to primary aluminium.

  4. 3. On the influence of Si on anodising and mechanical properties of cast aluminium alloys

    Författare :Baiwei Zhu; Caterina Zanella; Salem Seifeddine; Peter Leisner; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; anodising; corrosion protection; mechanical properties; Al-Si-baserade gjutningslegeringar; anodisering; korrosionsskydd; mekaniska egenskaper;

    Sammanfattning : The combination of two cost-effective processes, i.e. casting and anodising, would be an interest for the aluminium component applications. However, there are some obstacles in the application of anodising on cast Al alloys. LÄS MER

  5. 4. Mathematical and Experimental Study on Filtration of Solid Inclusions from Molten Aluminium and Steel

  7. 5. Mechanical Properties of Semi-Solid Al Castings : Role of Stirring

    Författare :Qing Zhang; Anders E.W. Jarfors; Stefan Jonsson; Jens Bergström; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; aluminium alloys; stirring; segregation; porosity; oxides; ductility; fatigue performance;

    Sammanfattning : Semi-solid metal (SSM) casting has been widely used in automotive industries to reduce the weight. In RheoMetalTM process which is one of the variations of SSM, the slurry fabrication can be finished within 30 second and can the slurry making process can be integrated into a high pressure die casting (HPDC) route without significant adjustments, making the process a promising alternative for industrial application.
