   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium alloys; Heat treatment; Solution treatment; Artificial ageing; Tensile properties; Plastic deformation; Microstructure; Modelling;

   Abstract : Environmental savings can be made by increasing the use of aluminium alloys in the automotive industry as the vehicles can be made lighter. Increasing the knowledge about the heat treatment process is one task in the direction towards this goal. The aim of this work is to investigate and model the heat treatment process for Al-Si casting alloys. READ MORE

4. 2. Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperature

   Author : Mohammadreza Zamani; Anders Jarfors; Sten Johansson; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si based casting alloys; elevated temperature; microstructural scale effect; Sr modification;

   Abstract : Aluminium alloys with Si as the major alloying element form a class of material providing the most significant part of all casting manufactured materials. These alloys have a wide range of applications in the automotive and aerospace industries due to an excellent combination of castability and mechanical properties, as well as good corrosion resistance and wear resistivity.

7. 5. On the Residual Stresses and Microstructure Formation of Aluminum-Silicon Cast Alloys

   Author : Mohsen Sadrossadat; Sten Johansson; Ru Lin Peng; Ingvar L Svensson; Linköpings universitet; []
   Keywords : Al-Si alloys; residual stresses; microstructure; microsegregation; nucleation behavior; modeling; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Cast aluminum-silicon alloys are being increasingly used in automotive and aerospace industries for critical structure applications because of their excellent castability, low density, acceptable mechanical properties and low cost. Different casting and heat treatment parameters largely affect the microstructure and residual stress of the components, which in turn, has a great impact on their mechanical properties. READ MORE
