  1. 1. 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

  3. 2. 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

  4. 3. Tennis and sports psychology : Mental toughness as a decisive factor in critical moments of elite male tennis

    University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för fysiologi, nutrition och biomekanik

    Author : Hamed Dares; Patrik Eriksson; [2023]
    Keywords : tennis; sport; psychology; mentality; coaching; tennis; idrott; psykologi; tränarskap; tränarlänktennis;

    Abstract : Introduction  The study is based on tennis and its connection to sport psychology. Matches are often five hourslong, against opponents who possess the same tennis skills as oneself. Mental toughness cantherefore be the deciding factor, especially over time. READ MORE

  5. 4. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

    University essay from KTH/Materialvetenskap

    Author : Shunyi Li; [2022]
    Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

    Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

  6. 5. Investigation of Heat Treatment and Quenching Cycles on Microstructure and Mechanical Properties of Hadfield Steel

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

    Author : Cécile Chaxel; [2022]
    Keywords : Hadfield steel; Manganese; Heat treatments; Carbides;

    Abstract : Hadfield steel is a material used in different industrial application, when a good resistance to severe impact loads and abrasion is expected. Its high ductility, high toughness, good work hardening capacity and high fatigue resistance make it especially suitable for theses conditions. READ MORE
