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

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Karl Ericsson; [2023]
    Keywords : Multivariate statistical process control; Batch processes; Quality prediction;

    Abstract : 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

    University essay from KTH/Hållfasthetslära

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Materialvetenskap

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

    Abstract : 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. READ MORE

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

    University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Author : Josu Najera Bernabeu; Alaitz Egaña Azkargorta; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 5. Theoretical investigation of Co-dependence in magnetic high-entropy alloys

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Johan-Michael Kurak; [2023]
    Keywords : ;

    Abstract : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. READ MORE
