  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. Intermetallic Compound Formation in Ni-Ti-Fe Powder Mixtures

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Tea Bertilsson; [2018]
    Nyckelord :Phase Evolution; Ni-Ti-Fe System; Intermetallics; Powder Metallurgy; Reactive Sintering; DSC; SEM; EDS; XRD; Technology and Engineering;

    Sammanfattning : The Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. LÄS MER

  4. 3. Hydrogen absorption properties of scandium and aluminium based compounds

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för materialkemi

    Författare :Adam Sobkowiak; [2010]
    Nyckelord :scandium intermetallics; hydrides; hydrogen storage materials; x-ray diffraction;

    Sammanfattning : In a time of global environmental problems due to overuse of fossil fuels, and a subsequent depletion of the supplies, hydrogen is considered as one of the most important renewable future fuels for use in clean energy systems with zero greenhouse-gas emission. Hydrogen storage is the main issue that needs to be solved before the technology can be implemented into key areas such as transport. LÄS MER

  5. 4. Synthesis and characterization of nano-structured CoSb3 thermoelectric material

    Master-uppsats, KTH/Materialvetenskap

    Författare :Abdullah Khan; [2009]
    Nyckelord :Thermoelectric CoSb3; Intermetallics; Spark Plasma Sintering; MS Thesis;

    Sammanfattning : In this project, nano powder of CoSb3 thermoelectric material was synthesized using chemical alloying novel co-precipitation method. This method involved co-precipitation of TE precursor compounds in controlled pH aqueous solutions followed by thermo-chemical treatments including calcination and reduction to produce nano-particulates of CoSb3.

  7. 5. The effect of rework on brittle fractures in lead free solder joints : The growth of intermetallic compounds during rework and its effects

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet

    Författare :Elin Dornerus; [2009]
    Nyckelord :Intermetalliska skikt; sprödbrott; lödfogar; blyfritt; Intermetallic layers; Intermetallic growth; brittle fractures; solder joints; lead free; RoHs;

    Sammanfattning : Saab Microwave Systems, SMW is a supplier of radar systems. The circuit boards that are operating in their radars have components which solder joints contains lead. However, the EU directive RoHs and WEEE are causing SMW to prepare for a transition to lead free solder joints. LÄS MER
