3. Hot Cracking and Grain Boundary Weaknesses of Nickel - Based 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.

4. Dynamics of high-angle grain boundary YBCO Josephson junctions
Abstract : This thesis describes experimental investigations of properties of high-angle YBa2Cu3O7−δ(YBCO)bicrystal Josephson junctions and SQUIDs fabricated on SrTiO3-substrates. The main focus of theinvestigation has been on the effects of the predominant d-wave symmetry of the superconductingwavefunction in YBCO on transport properties and dynamics. READ MORE

5. Grain Boundary Structure of YBa2Cu3O7-δ High Tc Superconductors
Abstract : The microstructures of YBa2Cu3O7-.delta. (YBCO) high Tc superconducting materials have been studied using analytical electron microscopy. The effects of processing parameters on the interfacial microstructures have been investigated in both bulk materials and thin films. READ MORE
