  1. 1. Precipitation analysis in bearing steel Hybrid 60

    University essay from KTH/Materialvetenskap

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

    Abstract : 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. READ MORE

  3. 2. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Filip Tuvenvall; [2023]
    Keywords : Machine Learning; Laser Ultrasonics; Material Properties; Steel; Hardness of Steel;

    Abstract : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. READ MORE

  4. 3. Experimental Evaluation of Time Study for Conventional Case Hardening at Härdservice

    University essay from

    Author : Binnu Kurian Mathew; Vishal Vijayan; [2022]
    Keywords : Case Hardening; Time Study;

    Abstract : Heat treatment is the process of heating metal without allowing it to reach a molten state or melting, it and then cooling it in a controlled manner to choose desired mechanical qualities. Heat treatment aims to make the metal stronger, more malleable, more abrasion resistant, and more ductile. READ MORE

  5. 4. DILATOMETRIC EVALUATION OF SOME CRITICAL PHYSICAL PROPERTIES OF OT75 AND OT101 STEEL GRADES

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

    Author : Wrya Mohamadian; [2021]
    Keywords : Steels; Martensite; Ms; Quenching; Heat treatment; Dilatometer; Mechanical property; Critical temperature; Phase transformation; hardness.;

    Abstract : Due to its hardness, martensite, perhaps, is the most desirable structure, but at the same time, martensite is very brittle. Balancing between hardness and brittleness is a challenge that steel manufacturers must deal with it. To decrease brittleness and to solve this problem, designers purposely temper the steel. Heat treatment, e. READ MORE

  6. 5. Characterization of Secondary Carbides in Low-Alloyed Martensitic Model Alloy Tool Steels

    University essay from KTH/Materialvetenskap

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

    Abstract : 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. READ MORE
