  1. 6. 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

  3. 7. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Jessica Jacobs; [2021]
    Nyckelord :;

    Sammanfattning : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. LÄS MER

  4. 8. Fabricability of a high alloy tool steel produced with LPBF, with a focus on part geometry

    Master-uppsats, Karlstads universitet

    Författare :Zulfaqar Abdelamir; [2021]
    Nyckelord :Addtive Manufacturing; Laser Powder Bed Fusion; High alloy Cold Work Tool Steel; Addtiv Tillverkning; LPBF; Höglegerat kallbearbetningsstål;

    Sammanfattning : Additive manufacturing (AM) is a promising manufacturing process that provides that ability to fabricate components with complex geometries with relatively low lead times compared to other manufacturing processes. This allows for more freedom of design, as prototypes can easily be produced throughout the development process. LÄS MER

  5. 9. Analysis of a Plate of High Strength Steel: Simulation of Impact and Determination of Residual Stresses

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Martin Hviid; [2021]
    Nyckelord :;

    Sammanfattning : In this study a finite element model has been created in ABAQUS/Standard in order to replicate impact tests performed by SSAB and to determine residual stresses in a plate. Uniaxial tensile tests have been done in order to determine the plastic behaviour of a high strength steel from the manufacturer SSAB and to determine whether the material can be assumed to be isotropic.

  7. 10. Simulation of Residual Stresses in Cemented Carbide

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Emma Lundin; [2021]
    Nyckelord :;

    Sammanfattning : Cemented carbides are used in a multitude of applications within machining as they can withstand tough conditions. Therefore, the stress state in a virgin material is of interest. LÄS MER
