  1. 1. Theoretical models of thermal conductivity and the relationship with electrical conductivity for compressed metal powder

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper; Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Sam Tran; Niklas Lindborg; Danilo De Souza Vivedes; Johanna Sjölund; Veronica Enblom; Mattias Sjödin; [2019]
    Nyckelord :;

    Sammanfattning : This Independent Project reviews literature about the effect of pressure and temperature on thermal conductivity in packed beds and its relationship with electrical conductivity. Exploring the relationships between thermal conductivity, porosity and pressure can give useful knowledge for further improvements in manufacturing processes in the field of powder metallurgy.

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

    Författare :Caroline Lejonklo; [2019]
    Nyckelord :Lean steel; Powder metallurgy PM ; Powder metallurgy steel PM steel ; Friction; Wear; Sliding contact; Lubricated; Porosity; Tribology; Adhesive wear; Abrasive wear; Gear; Gear tooth; Particles; Polyalphaolefin 8 PAO 8 ; Contact pressure; Density; Light optical microscopy LOM ; Scanning electron microscopy SEM ; Energy-dispersive X-ray spectroscopy EDS ; Vertical svanning interferometry VSI ; Pin on disc; Pin-on-disc;

    Sammanfattning : A fairly new technology used to produce metallic components is powder metallurgy (PM). Among the advantages with this technique are decreased cost of production for complex-shaped parts, new alloys are made possible, reduced end processing, less material loss, and vibrational damping effects.

  4. 4. Evaluation of Different Concepts for Pressed and Sintered Connecting Rods

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

    Författare :Mattias Rehn; [2019]
    Nyckelord :Connecting Rod; Con Rod; Fatigue; Buckling; Manufacturing; Höganäs AB; CAD; FEM; FEA;

    Sammanfattning : Connecting rod are found in most combustion engines and transmits thrust from the piston to the crankshaft. The connecting rod needs to withstand forces from the piston and inertia forces which results in axial tension, compression stresses and bending. LÄS MER

  5. 5. Investigation and Evaluation of Metal Powder Characterization Techniques : Currently available at the KTH Department of Material Science and Engineering

    Kandidat-uppsats, KTH/Materialvetenskap; KTH/Materialvetenskap

    Författare :Leo Hultén; Philip Jansson; [2018]
    Nyckelord :Powder Metallurgy; Metal Powder Characterisation; Evaluation; Investigation; Metal Powder Characterisation Techniques; assessment;

    Sammanfattning : The KTH Department of Materials Science and Engineering has lacked powder metallurgy research for many years, and as this field is constantly gaining in importance, such research needs to be reestablished. This requires the department to be able to accurately and efficiently characterize the properties of a powder, such as size distribution and composition, and in the short term, this needs to be done using non-specialized equipment.
