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

   Author : Salem Seifeddine; Birger Karlsson; Linköpings universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

6. 4. Rheocasting of aluminium alloys : Process and components characteristics

   Author : Mostafa Payandeh; Anders E. W. Jarfors; Magnus Wessén; Helen Atkinson; Jönköping University; []

   Abstract : Semi-Solid Metal (SSM) casting is a promising technology offering an opportunity to manufacture net-shape, complex geometry metal components in a single operation. However, the absence of foundry guidelines and limited design data for SSM casting makes it challenging to predict the performance of both process and components. READ MORE

7. 5. On Tool Failure in Die Casting

   Author : Anders Persson; Sture Hogmark; Jens Bergström; Torsten Eriksson; Uppsala universitet; []

   Abstract : Die casting is a very cost-efficient method of forming thin-walled and complex near net-shaped products with close geometric tolerances and good surface finish. A permanent die tool is used to make large quantities of identical products. The performance and tool life are limited by several mechanisms, e.g. READ MORE
