  1. 1. Evaluation of Crack Depth Meter - An investigation of the crack depth meters possibilities and limitations for commonly occurring damage mechanisms

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Alfred Norberg; [2023]
    Nyckelord :Crack depth measurement; RMG 4015; ACPD; Damage Mechanism; Evaluation; FEM Simulation; Sprickdjupsmätning; RMG 4015; ACPD; Skademekanism; Utvärdering; FEM-simulering;

    Sammanfattning : In this master thesis, the accuracy of the crack depth meter RMG 4015 was evaluated for different types of cracks with various damage mechanisms. In total, 61 crack depth measurements were conducted with the crack depth meter on 56 cracks which were located in the 23 different test pieces supplied by Kiwa. LÄS MER

  3. 2. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER

  4. 3. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Paulo Urrea Molina; [2023]
    Nyckelord :;

    Sammanfattning : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).

  5. 4. Analysis of degradation of melamine and polyurethane paint systems using different characterization methods. An investigation of automotive paints on trucks

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Oscar Sångberg; [2022]
    Nyckelord :Paint; degradation; analysis; melamine; polyurethane; Färg; nedbrytning; analys; melamin; polyuretan;

    Sammanfattning : Sammanfattning på svenska: Billacker är exponerade för solljus och nederbörd under hela lackens livslängd. Lacker behöver motstå faktorer i omgivningen som påverkar nedbrytningen för att leva upp till högt ställda visuella krav. LÄS MER

  7. 5. Preparation and Experimental Investigation of the Tribological Properties of Conductive Grease Containing Ionic Liquids

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