  2. 1. Imperfections in Recycled Aluminium-Silicon Cast Alloys

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

    Abstract : 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. READ MORE

  4. 2. Study of solidification and volume change in lamellar cast iron with respect to defect formation mechanisms

    Author : Péter Svidró; Pär Jönsson; Pål Schmidt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lamellar cast iron; shrinkage porosity; solidification; volumetric change; dendrite coherency; inter-dendritic space;

    Abstract : Lamellar cast iron is a very important technical alloy and the most used material in the casting production, and especially in the automotive industry which is the major consumer. Beside the many great properties, it is inclined to form casting defects of which some can be prevented, and some may be repaired subsequently. READ MORE
