  5. 24. Development of a ferritic ductile cast iron for improved life in exhaust applications

    Författare :Madeleine Ekström; Stefan Jonsson; Pamela Henderson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material development; SiMo51; HK30; exhaust manifolds; high-temperature corrosion; high-temperature low-cycle fatigue;

    Sammanfattning : Due to coming emission legislations, the temperature is expected to increase in heavy-duty diesel engines, specifically in the hot-end of the exhaust system affecting components, such as exhaust- and turbo manifolds. Since the current material in the turbo manifold, a ductile cast iron named SiMo51, is operating close to its limits there is a need for material development in order to maintain a high durability of these components.
