  1. 1. Influence of nitrocarburization on the thermomechanical fatigue properties of ductile iron for exhaust components : Analysis and comparisons of TMF-properties

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Karl Larsson; [2019]
    Keywords : Thermo-mechanical fatigue; low cycle fatigue; thermal strain; ductile cast iron; nitrocarburizing;

    Abstract : New stricter environmental legislation requires lower emissions and fuel consumption of automotive engines. Therefore the fuel efficiency must be increased but this leads to higher loads in the engine. As for the exhaust system it is affected by higher thermomechanical loads. READ MORE

  2. 2. Evaluation of material properties after laser welding on ductile cast iron

    University essay from KTH/Materialvetenskap

    Author : Olivia Taivalkoski; [2019]
    Keywords : Laser welding; ductile cast iron;

    Abstract : Scania wants to lower the weight of their trucks, including the goal to reduce the carbon dioxide emissions, and one way to do that is to use laser welding instead of fastenings.This bachelor thesis work is about laser welding of ductile cast iron, or spheroidal graphite cast iron or nodular cast iron, to QT-steels and case hardening steel and evaluation of the mechanical properties of the weld.

  3. 3. Influence of Nitrocarburization on Thermo-Mechanical Fatigue Properties : Material Characterization of Ductile Cast Iron for Exhaust Components

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Wännman Sofia; [2018]
    Keywords : Ductile cast iron; Nitrocarburizing; Thermo-mechanical fatigue;

    Abstract : The large number of vehicles operating on the roads cause high emissions and consequently a negative effect on the environment. When developing and optimizing internal combustion engines, certain requirements must be considered, which are environmental regulations, reduced fuel consumption and increased specific power.

  4. 4. Numerical Simulation of Ductile Cast Iron Fracture : A parameterization of the material model *MAT_224 in the FE-code LS-DYNA

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Viktor Eriksson; [2015]
    Keywords : ;

    Abstract : In crashes, fracture of Ductile Cast Iron (DCI) components can have a big influence on the global behaviour of the structure and the survival probability of the driver.In this thesis the material model *MAT_224 is parameterized for one ferritic-pearlitic grade, SS-0727-02, of DCI.

  5. 5. Study of Dross in Ductile Cast Iron Main Shafts

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Sofia Andersson; [2015]
    Keywords : Dross; Mg treatment; Main shafts; Ductile cast iron;

    Abstract : The study of dross in ductile cast iron main shafts was performed at Global Castings Guldsmedshyttan AB and presented in this master thesis. The purpose of the study was to obtain answers to why dross defects were present in some of the foundry's casted main shafts, with the main problem located at the flange of the shaft. READ MORE
