  1. 1. Evaluation of a novel method to investigate diffusion between copper-zinc alloys and cemented carbides

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :André Larsson; [2022]
    Nyckelord :Diffusion; Brass; Copper alloys; Copper zinc alloys; Wear; Cemented carbide; Diffusion couple;

    Sammanfattning : When slow wear mechanisms are studied it is important to examine slower processes, such as diffusion. Such processes can have a significant impact over time and can cause other phases to form, which can have a large effect on the wear. LÄS MER

  3. 2. 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

  4. 3. Performance and Wear Behavior of Ultra-Hard Cutting Tools during Machining of Titanium Alloy

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Rebecka Lindvall; [2018]
    Nyckelord :Metal cutting; Machining performance; Titanium machining; Ti6Al4V; α β -alloy; Tool wear; Wear mechanisms; Cost efficiency; Colding analysis; Cemented carbide; PCD; pcBN; TEM; Technology and Engineering;

    Sammanfattning : Since the 1950’s, a wide range of titanium alloys has been developed. Attractive titanium properties are the high strength-to-weight ratio, resistance towards corrosion, low thermal conductivity and low thermal expansion. LÄS MER

  5. 4. Investigation of Microstructure and Mechanical Properties in Hot-work Tool Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Tomas Rey; [2017]
    Nyckelord :hot-work tool steel; secondary carbide precipitation; precipitation hardening; tempering; carbide reactions; precipitation simulation; microstructure;

    Sammanfattning : Hot-work tool steels make up an important group of steels that are able to perform with good strength and toughness properties at elevated temperatures and stresses. They are able to gain this behavior through their alloy composition and heat treatment, which relies on the precipitation of alloy carbides to counter the loss in strength as the tempered material becomes more ductile.

  7. 5. Self-Desiccation of Self-Levelling Flooring Products and Investigations of Different Moisture Measurement Methods

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Byggnadsmaterial

    Författare :Christoffer Smith; Simon Tikkanen Jönn; [2016]
    Nyckelord :self-levelling compounds; moisture content; relative humidity; oven drying; carbide method; isothermal calorimeter; Technology and Engineering;

    Sammanfattning : Self-levelling flooring compounds (SLCs) are mainly used on concrete floors. Their purpose is to smooth the floors and make them horizontal. The fact that they are self-levelling means that they spread out like water over the floor before hardening to a horizontal layer. Some of them are also advertised as being self-desiccating. LÄS MER
