  1. 1. Teoretisk undersökning av bulkstrukturer av YSZ och en tvillinggräns av t-ZrO2 med DFT

    Kandidat-uppsats, Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Författare :Ali Tayebi; Fanny Andersson; [2022]
    Nyckelord :DFT;

    Sammanfattning : The material yttria-reinforced zirconia (YSZ) is widely used in biomedical applications and is the latest material in dentistry for the production of dental implants such as crowns and bridges. The used concentrations of yttria in zirconia are usually between 3-8 mol% Y2O3 dissolved in the ZrO2 structure, which stabilizes ZrO2 in tetragonal structure at RT. LÄS MER

  3. 2. Corrosion of additively manufactured magnesium alloy WE43 : An investigation in microstructure and corrosion properties of as built samples manufactured with Powder Bed Fusion-Laser Beam

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

    Författare :Clarence Wahman; [2021]
    Nyckelord :Mangesium; WE43; corrosion; additive manufacturing; biodegradable implants; microstructure; surface roughness; Magnesium; WE43; korrosion; additiv tillverkning; resorberbara implantat; mikrostruktur; ytråhet;

    Sammanfattning : The work presented in this thesis was conducted at Uppsala University and at Swerim AB. The study aims to broaden the knowledge about the corrosion of additively manufactured bioresorbable alloy WE43 in humanlike conditions for future applications. LÄS MER

  4. 3. Factors governing marble lightness in peripheral alteration haloes around carbonate-hosted Zn-Pb-Ag-(Cu-Au) deposits, Garpenberg, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Marcus Eriksson; [2020]
    Nyckelord :Carbonate; Zn; Pb; Ag; Cu; Au; Alteration haloes; marble; lightness; Bergslagen; Garpenberg;

    Sammanfattning : A Master thesis about the Garpenberg deposit located in Bergslagen, a lithotectonic domain, with a mining history that might date back as far as 350 BC. Marble- and skarn-hosted sulfide deposits are found in the area, which creates the opportunity to mine both limestone and sulfidic ore in a single mine. LÄS MER

  5. 4. Application of some modern analytical techniques for investigations of non-metallic inclusions in steel samples

    Master-uppsats, KTH/Materialvetenskap

    Författare :Wan Zhiyue; [2018]
    Nyckelord :Non-metallic Inclusions; Electrolytic Extraction; Fractional Gas Analysis; Zirconium Addition; Calcium Treatment;

    Sammanfattning : The non-metallic inclusions (NMI) have large influence on steel properties. Therefore, evaluation of inclusion size, number, composition and morphology by using modern analytical techniques are very important for control of steel production and steel quality. Three dimensional analysis method of electrolytic extraction is applied in this work. LÄS MER

  7. 5. Investigation of the possibility for using ZrO2 and ZrSiO4 for Zr additions to liquid ferrosilicon

    Master-uppsats, KTH/Materialvetenskap

    Författare :Amanda Vickerfält; [2017]
    Nyckelord :inoculant; ferrosilicon; zirconium; zirconia; zircon sand;

    Sammanfattning : Ferrosilicon containing 50-75% Si and 1.0-5.0% Zr is used as inoculant in the cast iron industry. Zr can be added to liquid ferrosilicon by use of Zr metal or zirconium ferroalloy (FeSiZr). LÄS MER
