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

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

   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

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

   Författare :Anton Bjurenstedt; Anders Jarfors; Salem Seifeddine; Pål Schmidt; Jönköping University; []
   Nyckelord :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

5. 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 :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.

7. 5. The effect of microstructural features, defects and surface quality on the fatigue performance in Al-Si-Mg Cast alloys

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

   Sammanfattning : Global warming is driving industry to manufacture lighter components to reduce carbon dioxide (CO2) emissions. Promising candidates for achieving this are aluminium-silicon (Al-Si) cast alloys, which offer a high weight-to-strength ratio, excellent corrosion resistance, and good castability. LÄS MER
