  1. 11. Investigating potential proton conductors: Doping BaTiO3 and SrTiO3 with Fe and Al

    University essay from Uppsala universitet/Strukturkemi

    Author : Julia Löfstrand; [2020]
    Keywords : Proton conductor; perovskite; solid state synthesis;

    Abstract : There are many interesting applications of proton conducting oxides, such as electrolytes in fuel cells, hydrogen sensors and catalytic membranes for hydrogenation or dehydrogenation of organic compounds. Previous work explored doping BaTiO3 with the Rare Earth Element (REE) Sc to introduce oxygen vacancies in the structure, making it a Proton Conductor (PC). READ MORE

  3. 12. Characterization of Heat Treated LMwD Ti-6Al-4V to Study the Effect of Cooling Rate on Microstructure and Mechanical Properties

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Edin; [2019]
    Keywords : Ti-6Al-4V; LMwD; Characterization; Alpha Laths;

    Abstract : In this work, the influence of different cooling rates (5, 20, 50 and 100 °C/s) on the microstructure and mechanical properties of Laser Metal Wire Deposited (LMwD) Ti-6Al-4V was investigated, this was done using a thermal-mechanical physical simulation system (Gleeble 3800, DSI). Two different soak times above β transus (held at 1100 °C), 5 and 40 s, were used and after cooling to 150 °C, the samples were tensile tested. READ MORE

  4. 13. Microstructural, Mechanical and Tribological Studies of Ti-6Al-4V Thin Plates Produced by EBM Process

    University essay from Högskolan Dalarna/Materialteknik

    Author : Onimisi Calistus Sanni; [2019]
    Keywords : Additive manufacturing AM ; Electron beam melting EBM ; Mechanical properties; Tribological behaviour; Microhardness; Micro tensile; Thin sections; Ti-6Al-4V;

    Abstract : The titanium alloy, Ti-6Al-4V, is vastly studied and used in many applications because it has a transformation microstructure, which can be tailored for apt properties that are consistent up to 500°C. Compared to conventional steels, this alloy favours certain applications due to its high specific strength, hardenability, corrosion resistance, biocompatibility and weldability. READ MORE

  5. 14. Short Carbon Fiber-Reinforced Thermoplastic Composites for Jet Engine Components

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Lena Brunnacker; [2019]
    Keywords : thermoplastic composites; short fiber;

    Abstract : State-of-the-art aircraft engine manufactures aim to reduce theirenvironmental impact steadily. Thereby they attempt to increase engineefficiency, use new renewable fuel sources and most importantly aim toreduce component weight. READ MORE

  6. 15. Growth and Characterization of CrB2/TiB2 Superlattices by Magnetron Sputtering

    University essay from Linköpings universitet/Tunnfilmsfysik; Linköpings universitet/Tekniska fakulteten

    Author : Samira Dorri; [2019]
    Keywords : Thin films; diborides; superlattices; reflectivity; transition-metal diborides; CrB2; TiB2;

    Abstract : In the present work, growth and structural characterization of CrB2/TiB2 superlattices on (0001) Al2O3 substrate is studied. The superlattices are grown using a direct current magnetron sputtering (DCMS) system with a base pressure of <9E-7 Torr. READ MORE
