  1. 1. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

    University essay from KTH/Materialvetenskap

    Author : Felicia Larsson; [2023]
    Keywords : ;

    Abstract : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. READ MORE
