  1. 1. The effect of recycling and processing routes on recrystallization in a secondary 3xxx aluminium alloy

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

    Författare :Anton Rolseth; [2023]
    Nyckelord :Aluminium alloys; sheet metal forming; grain boundary segregation; recrystallization; Zener pinning; casting; rolling;

    Sammanfattning : Aluminium alloys have the possibility to be infinitely recycled. By only generating 5% of the emissions compared to primary aluminium, great CO2 savings can be made. One of the issues in manufacturing components entirely from post-consumer scrap is the presence of trace elements and impurities. Such elements can be Fe, Cu, Cr, P and Pb. LÄS MER

  3. 2. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER

  4. 3. Experimental studies of radiation damage in uranium nitride

    Master-uppsats, KTH/Fysik

    Författare :Maria Giamouridou; [2023]
    Nyckelord :uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

    Sammanfattning : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. LÄS MER

  5. 4. Comparative investigation of micromechanisms of plastic deformation by in-situ tensile tests of highly textured 316L steel

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Subhani Kumarasinghe; [2022]
    Nyckelord :Additive manufacturing; texture control; plastic deformation;

    Sammanfattning : Additive manufacturing (AM) is identified as one of the best techniques in manufacturing components addressing most of the current challenges including material scarcity, design complexity, material compatibility, etc. Stainless steel 316L is one of the promising material candidates in AM due to its extraordinary properties that are useful in a wide variety of industries.

  7. 5. Electron Backscatter Diffraction (EBSD) Analysis and Predicted Physical Properties of Shocked Quartz from the Chicxulub Impact Crater, Mexico

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Erina Prastyani; [2022]
    Nyckelord :EBSD; SEM; shocked quartz; quartz; CPO; seismic velocity; anisotropy; Chicxulub; impact crater; pole figures; MTEX toolbox; microstructural features; planar deformation feature; planar fracture; feather features;

    Sammanfattning : As one of the most common minerals in crustal rocks, quartz has been widely used as an indicator for shock metamorphism. Shocked quartz is found in the Chicxulub impact crater, an impact crater that has been linked to the Cretaceous-Tertiary extinction ~66 million years ago. LÄS MER
