  2. 2. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    Författare :Salem Seifeddine; Birger Karlsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik; Aluminium; microstructure; porosity; tensile properties; modelling.; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. LÄS MER

  3. 3. Imperfections in Recycled Aluminium-Silicon Cast Alloys

    Författare :Anton Bjurenstedt; Anders Jarfors; Salem Seifeddine; Pål Schmidt; Jönköping University; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Imperfections; Recycled cast Al-Si alloy; Fe-rich particles; Melt quality; Fractography; Differential scanning calorimetry.;

    Sammanfattning : In striving to produce high quality cast components from recycled aluminium alloys,imperfections have to be considered, because recycled aluminium usually containsmore of it. However, there are great energy savings to be made by using recycledaluminium; as little as 5% of the energy needed for primary aluminium productionmay be required. LÄS MER

  4. 4. 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 :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

  5. 5. The influence of microstructure on the crack initiation and propagation in Al-Si casting alloys

    Författare :Toni Bogdanoff; Salem Seifeddine; Ehsan Ghassemali; Anders E.W. Jarfors; Johan Moverare; Jönköping University; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum-Silicon alloys; scanning electron microscopy; material characterization; fatigue performance; digital image correlation;

    Sammanfattning : For reducing the CO2 footprint in many industrial fields, the goal is to produce lighter components. The aluminium-silicon (Al-Si) cast alloys are promising candidates to fulfill these goals with a high weight-to-strength ratio, good corrosion properties, excellent castability, and recyclable material.
