  1. 1. The Application of Multivariate Statistical Process Control during Industrial Hot Isostatic Pressing Sintering Processes : A Case study at Seco Tools AB

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Karl Ericsson; [2023]
    Nyckelord :Multivariate statistical process control; Batch processes; Quality prediction;

    Sammanfattning : This Master's thesis focuses on improving the understanding and monitoring of the Hot Isostatic Pressing (HIP) sintering process used by Seco Tools AB to manufacture cemented carbides for cutting tools. While essential for producing cutting tools with superior hardness and toughness the HIP sintering process introduces a complex relationship between the selected process parameters and the achieved materials properties.

  3. 2. Impact of Residual Stress on the Warm Pre-Stressing Effect

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Emil Danielsson; [2023]
    Nyckelord :Warm Pre-Stressing effect; Residual stress; Cleavage fracture; Ferritic Steel; Fracture mechanics; Varm förspänning; Restspänningar; Klyvbrott; Brottmekanik; Ferritiskt stål;

    Sammanfattning : Irradiation of a reactor pressure vessel (RPV) causes a shift of the ductile to brittle transition region towards higher temperature regions. In the event of a pressurized thermal shock (PTS), where the temperature drops drastically, the ductile to brittle transition region might be entered for irradiated ferritic steel. LÄS MER

  4. 3. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    Master-uppsats, KTH/Materialvetenskap

    Författare :Helena Ek Jendrny; [2023]
    Nyckelord :AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Sammanfattning : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. LÄS MER

  5. 4. “Vita, Till Största Delen Kristna, Skötsamma Riktiga Flyktingar, Välkomnar Vi Såklart!” : En Netnografisk Studie Om Positiva Attityder Till Invandring På Flashback

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för samhällsstudier (SS)

    Författare :Julia Haarberg; Olle Johansson; [2023]
    Nyckelord :Netnography; Refugees; Racialization; Integration; Minority-groups; Culture;

    Sammanfattning : This study aims to examine positive attitudes towards a certain group of immigrants in a group that is normally negative against them. Furthermore creating an understanding of their perception of what a “real” refugee is. LÄS MER

  7. 5. Surface treatment methods for metal components trays and frames

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Josu Najera Bernabeu; Alaitz Egaña Azkargorta; [2023]
    Nyckelord :;

    Sammanfattning : The proper selection of materials and surface treatment is critical in ensuring the strength, durability, and safety of metal structures in various environments. Therefore, this project is being developed in collaboration with Aurobay Company to explore and provide insights into the most suitable material and surface treatment method for a frame. LÄS MER
