2. 6. The influence of microstructure on the crack initiation and propagation in Al-Si casting alloys

   Author : Toni Bogdanoff; Salem Seifeddine; Ehsan Ghassemali; Anders E.W. Jarfors; Johan Moverare; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum-Silicon alloys; scanning electron microscopy; material characterization; fatigue performance; digital image correlation;

   Abstract : For reducing the CO2 footprint in many industrial fields, the goal is to produce lighter components. The aluminium-silicon (Al-Si) cast alloys are promising candidates to fulfill these goals with a high weight-to-strength ratio, good corrosion properties, excellent castability, and recyclable material.

4. 7. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components

   Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Torsten Sjögren; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; Structural analysis; Mechanical behaviour; Casting process simulation; Finite element method simulation;

   Abstract : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.

5. 8. Simulation of Microstructure-based Mechanical Behaviour of Cast Components

   Author : Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Franco Bonollo; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; structural analysis; mechanical behaviour; casting process simulation; Finite Element Method FEM simulation;

   Abstract : In the process of developing cast iron and cast aluminium components, a high level of co-operation between product development and production is of great importance. From an engineering standpoint, this co-operation is limited early in the product development phase by e.g. READ MORE

6. 9. High performing cast aluminium-silicon alloys

   Author : Martin Riestra; Salem Seifeddine; Ehsan Ghassemali; Jessica Elfsberg; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium cast alloys; melt quality; eutectic modification; grain refinement; microstructure; tensile properties;

   Abstract : The need to produce lighter components due to environmental aspects and the development of electrical vehicles represents an opportunity for cast aluminium-silicon alloys. With high specific strength, good castability, high corrosion resistance and recyclability, these alloys offer an attractive combination of properties as an alternative to steel, cast iron and titanium-based components in certain applications.

7. 10. Heat treatment of Al-Si-Cu-Mg casting alloys

   Author : Emma Sjölander; Salem Seifeddine; Ingvar Svensson; Sten Johansson; Jönköping University; []
   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
