2. 1. Investigations on the Formation of Defect Bands in Semi-Solid High Pressure Die Cast Aluminium-Silicon Alloys

   Author : Madeleine Law; Pär Jönsson; Christopher Hulme-Smith; Taishi Matsushita; Jessica Elfsberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Semi-Solid Metals; SSM; Al-Si Alloys; Defect bands; HPDC; Semisolida metaller; SSM; Al-Si-Alloys; defektband; HPDC; Metallurgical process science; Metallurgisk processvetenskap;

   Abstract : High-pressure die casting of semi-solid aluminium-silicon alloys is used in the automotive industry to manufacture components, like housings, brackets, and bars. It is commonly known that during high-pressure die casting, defect bands may be created that follow the contour of the component surface. These bands consist mainly of a eutectic phase. READ MORE

4. 2. Rheocasting of Aluminium Alloys : Slurry Formation, Microstructure, and Properties

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

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

   Abstract : 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. READ MORE

   Author : Jorge Santos; Anders E.W. Jarfors; Arne Dahle; Hongbiao Dong; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; semi-solid casting; aluminium alloys; dissolution; grain refinement; segregation; intermetallic phases; heat treatment; mechanical properties; fatigue properties; Rheometal™ processen; semi-solid gjutgarna; aluminiumlegeringar; upplösning; kornförfining; segregering; intermetalliska faser; värmebehandling; mekaniska egenskaper; utmattningsegenskaper;

   Abstract : The use of lightweight parts by the vehicle industry produces immediate benefits on the reduction of emissions because less energy is consumed during the production, service, and recycle stages of a product life cycle. Therefore, the development of processes that allow high design freedom for topology optimisation and materials with high specific strength is a great need. READ MORE

7. 5. Mechanical properties of semi-solid Al castings : Role of stirring

   Author : Qing Zhang; Anders E.W. Jarfors; Stefan Jonsson; Tomas Liljenfors; Arne K. Dahle; Johan Ahlström; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; aluminum alloys; stirring; segregation; porosity; oxides; ductility; fatigue performance; melt quality;

   Abstract : Aluminum castings have been widely used in the automotive industry to reduce the vehicle's weight. However, the existence of casting defects significantly limits its application. The most common and detrimental defects in aluminum castings are porosity and oxides. READ MORE
