  1. 1. Influence of microstructure on surface characteristics in cold-deformed stainless steel tubes

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Fredrik Ottenklev; [2019]
    Nyckelord :Cold deformation; surface roughness; strain; microstructure; austenitic stainless steel; grain rotation; Technology and Engineering;

    Sammanfattning : Cold deformation of metals is known to induce roughness on their free surface. In some of the processing equipment of Tetra Pak processing systems, tubes of austenitic stainless steel 316L are used. During the production of this processing equipment, such tubes are occasionally cold-deformed. LÄS MER

  3. 2. Evaluating the interaction between CC-studs and pavement

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

    Författare :Elias Helou; [2019]
    Nyckelord :;

    Sammanfattning : Studded tyres are used in many countries around the world. Excessive wear of the road is the result when using studded tyres, and thus time of usage is limited or prohibited. A stud consists of a hard metal part enclosed in steel, aluminium, plastic or rubber, which is anchored in the tyre. LÄS MER

  4. 3. Surface Roughening of PET Meltspun Filament through Minor Phase Removal of Blend

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Farzad Zanganeh; [2018]
    Nyckelord :Roughening; Phase induced morphology; PET PS blend; Hydrophobicity; Drawing; Annealing;

    Sammanfattning : Superhydrophobic fabrics have gained a huge interest in the industries recently. New legislation pushes the industries to eliminate the use of fluorinated materials in the production of these type of fabrics. LÄS MER

  5. 4. CO induced faceting of Rh(553)

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Ka Sin Lai; [2015]
    Nyckelord :Science General;

    Sammanfattning : We have investigated the CO induced faceting of a Rh(553) surface using Scanning Tunneling Microscope (STM), Low Energy Electron Diffraction (LEED) and Auger Electron Spectroscopy (AES). The sample was exposed to a CO pressure of 1x10^-3 mbar, at different sample temperatures. LÄS MER

  7. 5. Friktionsbeteende i tågbromsar under inverkan av snö

    Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Niklas Spångberg; Konrad Lindblad; [2010]
    Nyckelord :;

    Sammanfattning : Institutionen för Maskinkonstruktion KTH har fått i uppdrag av Stockholms Lokaltrafik att studera friktion, nötning och temperatur mellan blockbromsmaterial och tåghjulmaterial. Detta sedan ett antal tåg med kompositblock mist bromsförmågan på Roslagsbanan under vintertid. LÄS MER
