1. 1. Semi-Solid Casting of Aluminium and Magnesium Alloys: Slurry Production and Rheocasting using the Rapid Slurry Forming Technology

   Författare :Olof Granath; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slurry; RheoMetal; Process parameter; Aluminium alloys; Semi-solid; Rheocasting; Rapid Slurry Forming; Magnesium alloys; Reheating;

   Sammanfattning : Semi-solid casting was developed in the early 1970’s and involves the use of a partially solidified metal slurry. This method of casting has become a popular alternative for production of automobile components. LÄS MER

3. 2. 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

4. 3. 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.

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

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

   Sammanfattning : 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. LÄS MER

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

   Författare :Madeleine Law; Pär Jönsson; Christopher Hulme-Smith; Taishi Matsushita; Jessica Elfsberg; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
