  2. 2. Hot Cracking and Grain Boundary Weaknesses of Nickel - Based Superalloys

    University dissertation from Stockholm : KTH

    Author : Joel Håkan Andersson; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot cracks; Notch rupture testing; Eutectic; Weldability; Varestraint testing; Grain boundary weaknesses; Superalloys;

    Abstract : Abstract Grain boundary weaknesses of nickel-based superalloys not only materialize during service in the hot turbine engine sections but also during the weld manufacturing. The performance, in this respect, of the most commonly used alloys at Volvo Aero Corporation (VAC), 718 and the higher temperature capacity Waspaloy, are therefore the main subjects for this thesis.

  3. 3. Atomistic modeling of interfaces in WC-Co cemented carbides

    University dissertation from Stockholm : KTH

    Author : Martin Petisme; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; analytic bond order potentials; weing; WC-Co; grain boundary sliding; grain boundaries; density functional theory; molecular dynamics; interfaces; cemented carbides;

    Abstract : Grain and phase boundaries are crucial in understanding the properties of real materials. In this thesis, interfaces in WC–Co cemented carbide are modeled atomistically using density functional theory (DFT) and analytic interatomic potentials. READ MORE

  5. 5. Nanoscale YBa2Cu3O7-δ devices -Searching for a subdominant order parameter using a single electron transistor

    University dissertation from Stockholm : KTH

    Author : David Gustafsson; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; grain boundary; Josephson junctions; YBCO; single electron transistors; high temperature superconductivity;

    Abstract : The microscopic origin of High critical Temperature Superconductivity (HTS) is still an open issue in condensed matter physics. It is believed that by exlporing the quasiparticle energy spectrum one can learn about the mechanism promoting the superconducting state. READ MORE
