  2. 11. Thermal Cycling, Creep- and Tensile Testing of Cast Exhaust Materials at Elevated Temperatures

    Author : Christian Öberg; Stefan Jonsson; Henrik Östling; KTH; []
    Keywords : creep; constant-load; thermal cycling; tensile test; cast materials; cast iron; exhaust materials.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : An exhaust manifold of a truck engine is subjected to tough conditions. As the truck is started, operated and shut down, it becomes subjected to thermal cycling up to around 800°C. At such high temperatures, corrosion, fatigue and creep are active degradation mechanisms. READ MORE

  4. 12. Residual Stresses and Fatigue of Shot Peened Cast Iron

    Author : Mattias Lundberg; Lin Peng Ru; Sten Johansson; Taina Vuoristo; Daniel Bäckström; Maqsood Ahmad; Jens Bergström; Linköpings universitet; []
    Keywords : ;

    Abstract : The complex geometry of cylinder head in heavy-duty diesel engine makes grey cast iron or compact graphite iron a perfect material choice due to its castability, thermal conductivity and damping capacity. To increase the efficiency of the engine, the fatigue property of the material needs to be improved. READ MORE

  6. 14. Creep Behavior of High Temperature Cast Materials for Exhaust Applications

    Author : Christian Öberg; Stefan Jonsson; Baohua Zhu; John Hald; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Creep; creep behaviour; creep damage; ductile cast iron; high-alloyed austenitic cast steel; thermal cycling; tensile testing; stress relaxation; oxidation; precipitation.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : This thesis focuses on creep of four cast materials intended for exhaust manifolds in heavy-duty truck engines. Two of the materials are ferritic ductile cast irons, SiMo51 and SiMo1000, one is an austenitic ductile cast iron, D5S, and another one is an austenitic cast steel, HK30. READ MORE

  7. 15. 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.
