  1. 1. Precipitation analysis in bearing steel Hybrid 60

    Master-uppsats, KTH/Materialvetenskap

    Författare :Rebecca Rosén; [2023]
    Nyckelord :martensitic steel; secondary hardening; precipitation; PRISMA; martensitiskt stål; sekundärhärdning; utskiljning; PRISMA;

    Sammanfattning : New materials are always being developed to get the best properties possible where needed. The way to create these materials and test them is also developing. When it comes to high-strength steels, a martensitic microstructure is a common choice. LÄS MER

  3. 2. Cybersecurity of remote work migration: A study on the VPN security landscape post covid-19 outbreak

    Kandidat-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Lukas Einler Larsson; Kushtrim Qollakaj; [2023]
    Nyckelord :Cybersecurity; Remote work; VPN; Exploit; Hardening;

    Sammanfattning : Background. The pandemic outbreak commenced a large migration of employees from all kinds of industries from previously working in an industrial or office environment to working from home. The remote migration allowed many kinds of work to continue as usual even during a pandemic. LÄS MER

  4. 3. Characterization of Secondary Carbides in Low-Alloyed Martensitic Model Alloy Tool Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Jubica Jubica; [2020]
    Nyckelord :martensitic steel; secondary hardening; precipitation; STEM; EDS; Prisma; size distribution; martensitiskt stål; sekundärhärdning; utskiljning; STEM; EDS; PRISMA; storleksfördelning;

    Sammanfattning : The development of tool steels for making and shaping other materials requires a better understanding of the material's properties during manufacture. These high-quality steels include many alloying elements, which give increased hardness during tempering. For producing hardened microstructures, austenite generation is essential. LÄS MER

  5. 4. Heat Treatment and Secondary Phase Formation in FeCrNi Medium Entropy Alloys

    Master-uppsats, KTH/Materialvetenskap

    Författare :Amanda Carsbring; [2020]
    Nyckelord :;

    Sammanfattning : The topics of high entropy alloys (HEA) and medium entropy alloys (MEA) have been heavily researched in recent years. A HEA usually consists of five or more base elements, and a MEA would have three or four base elements. LÄS MER

  7. 5. Dilatometry Study of a High-Chromium Cast Iron

    Master-uppsats, KTH/Hållfasthetslära (Avd.)

    Författare :Benjamin Solem; [2018]
    Nyckelord :;

    Sammanfattning : High-chromium cast irons are used in certain applications where the demand on abrasion resistance is high. Such applications can be found in the milling industry and in pumps for transport of abrasive particles in liquid suspension. Soft annealed high-chromium cast iron containing 2.6 % C and 24. LÄS MER
