  1. 1. Characterization of surface defects caused by ultrasonic cleaning of aluminium

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

    Författare :Emanuel Eriksson; [2022]
    Nyckelord :Ultrasonic cleaning; surface cleaning; metal; aluminium; 7050; 2050; defects; surface defects; Energy Dispersive Spectroscopy; Scanning Electron Microscopy; Vertical Scanning Interferometry;

    Sammanfattning : This master thesis studies the behaviour of two aluminium alloys in ultrasonic cleaning at two different intensities, as well as the effect of a cleaning solution, Formula 815 GD-NF on the same surface have been studied with respect to surface roughness and material composition. Methods like Light Optical Microscopy (LOM), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and 3D topography using white light interferometry (VSI) was used to study the surface and material composition.

  4. 4. A method for developing stress-strain relationships using Nanoindentations

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Ludvig Lindsjö; Fanny Linander; [2021]
    Nyckelord :Nanoindentation; Material Science; Steel; Solid Mechanics; Technology and Engineering;

    Sammanfattning : This thesis is a material science research collaboration between the Division ofProduction and Materials Engineering at Lund Faculty of Engineering and theComputer-Aided Engineerings group at BorgWarner, Landskrona. The objectiveof the thesis is to explore the convertion of nanoindentation load-depth curves intotensile stress-strain curves, and to provide BorgWarner Landskrona with nanoin-dentation data on materials used in their standard production.

  5. 5. Evaluation of different non-metallic inclusions in steel chips by using electrolytic extraction : Evaluation of a methodology for electrolytic extraction and scanning electron microscopy - energy dispersive spectroscopy (SEM-EDS) analysis

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Niklas Jespersson; Torbjörn Sandberg; [2021]
    Nyckelord :;

    Sammanfattning : Analysing non-metallic inclusions (NMI) by conventional microscopy is prone to errors.  Better imaging can be achieved by using electrolytic extraction (EE) to effectively dissolve the metal matrix, freeing the inclusions so that they can be collected on a filter. LÄS MER
