  1. 1. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Industriell Produktion

    Författare :Christian Jaunviksna; [2023]
    Nyckelord :Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

    Sammanfattning : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. LÄS MER

  3. 2. Air Cooling Analysis of Forged Bearing Steels

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Mattias Sörlander; [2022]
    Nyckelord :Material; Bearing steel; Cooling;

    Sammanfattning : This thesis work was done in cooperation with Ovako Sweden AB in Hofors to better understand and improve cracking-related problems in bearing ring production and cooling after forging in particular. This goal was achieved by doing a literature search and executing cooling experiments in live production. LÄS MER

  4. 3. Optimisation of local material parameters : Optimising local material parameters in ductile cast iron cylinder head casting

    Magister-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Katri Mäkinen; [2021]
    Nyckelord :Casting simulation; Material parameter; Ductile cast iron; Optimisation; Local material parameters; Silicon content; Pearlite; Ferrite;

    Sammanfattning : The constantly tightening emission regulations demand the engines to be moreefficient, to get more power out of smaller engines. Higher engine loads andcomponent temperatures are causing more stresses to engine components. LÄS MER

  5. 4. Develop Optimization Model for Spheroidal Graphite Iron

    Master-uppsats,

    Författare :Rehman Babar; [2020]
    Nyckelord :;

    Sammanfattning : The main motivation behind this study is to develop a methodology to generate surrogate model coefficients for parametrized Spheroidal Graphite Iron (SGI) for thermal expansion and Young’s modulus response. To accomplish this objective, a 3D model was created by Abaqus, and Python was used for developing the script. LÄS MER

  7. 5. Casting and Characterization of Advanced High Strength Steels

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser
