2. 1. Fatigue strength of engineering materials : the influence of environment and porosity

   Author : Jan Linder; Bengt Lindberg; Lennart Josefsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; cast aluminium; hardened steels; fatigue; corrosion; crack propagation; spot weld; porosity; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : The objective of this work was to use LEFM in order to assess the detrimental influence of surrounding chloride-containing environments for stainless steels, hardened steel as well as for a cast aluminium alloy. An additional aim was also to use LEFM to assess the influence of porosity on the fatigue properties for different commercial cast aluminium alloys and manufacturing methods. READ MORE

4. 2. 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.

5. 3. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications

   Author : Elanghovan Natesan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder head; aluminium; constitutive models; thermo-mechanical fatigue; fatigue; ageing; mechanical behaviour; A356;

   Abstract : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.

6. 4. Fatigue Assessment of Friction Stir Welded Joints in Aluminium Profiles

   Author : Meysam Mahdavi Shahri; Rolf Sandström; Per Jahn Haagensen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; Fatigue; Aluminium alloys; Critical distance; Finite element method; Standard codes;

   Abstract : Friction stir welding (FSW) is a low heat input solid state welding technology. It is often used for fabrication of aluminium alloys in transportation applications including railway, shipbuilding, bridge structures and automotive components. READ MORE

7. 5. Deformation Behaviour of A356-T7 Cast Aluminium Alloys Used in High Specific Power IC Engine Cylinder Heads

   Author : Elanghovan Natesan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloys; fatigue; constitutive models; thermo-mechanical fatigue; a356; cylinder head;

   Abstract : The constant development drive towards higher specific power and lower displacement engines in recent years to produce environmentally friendly high-performance cars has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.
