  1. 1. Effect of Proton Irradiation on the Mechanical Properties of Fe-10Cr-4Al in Liquid Lead

    Master-uppsats, KTH/Fysik

    Författare :Gabriela Lapinska; [2023]
    Nyckelord :Fe-10Cr-4Al; Lead; Radiation Damage; Slow Strain Rate Testing; Fe-10Cr-4Al; bly; strålskador; Slow Strain Rate Testing;

    Sammanfattning : Among the structural materials under consideration for future lead-cooled fastreactors, special attention is paid to ferritic Fe-10Cr-4Al due to its superior corrosionand erosion protective properties, as well as its insensitivity to liquid metalembrittlement in liquid lead. This thesis gives an inside look into the radiation damageproperties of the alloy and the possible embrittlement scenarios. LÄS MER

  3. 2. Reinforced Biodegradable Polymer Composite Material based on Japanese Washi Paper

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - Ångström

    Författare :Lovisa Rova; [2022]
    Nyckelord :biodegradable; polymer; composite; paper-based; washi; poly butylene succinate ; biodegradation;

    Sammanfattning : In this study, traditional Japanese washi paper was sandwiched with poly(butylene succinate)(PBS) in order to produce a paper-based composite material that can be biologically degraded. Specimens were prepared using a hot press, and the mechanical properties of the washi paperand the new composite material were investigated by tensile tests. LÄS MER

  4. 3. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries

    Master-uppsats, KTH/Materialvetenskap

    Författare :Yang Yang; [2020]
    Nyckelord :Residual Stresses; Cast Iron; Engine Components; XRD; Ultrasonic; Cutting;

    Sammanfattning : Cast iron, taking the advantages of the advanced castability forming components of complex geometries and favorable mechanical properties, is employed in engine components in truck industries. Compacted graphite iron (CGI) integrates both merits of lamellar graphite iron (LGI) and spheroidal graphite iron (SGI) such as good machinability and high thermal conductivity from LGI, high ultimate tensile strength (UTS), good fatigue resistance, high elastic modulus, and high ductility from SGI, thus is now becoming a competitive alternative of traditional LGI in cylinder blocks and heads.

  5. 4. Characterization of Heat Treated LMwD Ti-6Al-4V to Study the Effect of Cooling Rate on Microstructure and Mechanical Properties

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Emil Edin; [2019]
    Nyckelord :Ti-6Al-4V; LMwD; Characterization; Alpha Laths;

    Sammanfattning : In this work, the influence of different cooling rates (5, 20, 50 and 100 °C/s) on the microstructure and mechanical properties of Laser Metal Wire Deposited (LMwD) Ti-6Al-4V was investigated, this was done using a thermal-mechanical physical simulation system (Gleeble 3800, DSI). Two different soak times above β transus (held at 1100 °C), 5 and 40 s, were used and after cooling to 150 °C, the samples were tensile tested. LÄS MER

  7. 5. Doing and undoing gender in Lithuanian media representations of alcoholism

    Kandidat-uppsats, Lunds universitet/Mänskliga rättigheter

    Författare :Ingrida Kaulinyte; [2018]
    Nyckelord :Media; Gender perspective; Lithuania; Alcoholism; Qualitative content analysis; Critical Discourse Analysis; Doing gender; Undoing gender; Butler; Bogren; Codependency; History and Archaeology;

    Sammanfattning : Uppsatsens syfte är att analysera hur genus kan göras och ogöras med fokus på kvinnor i relation med alkoholiserade män samt hur det avspeglar och påverkar marginalisering i det litauiska samhället. Undersökningen är avgränsad till en tidsperiod oktober 2016 och oktober 2018 och fokuserar på Litauen. LÄS MER
