4. 2. Weld Cracking in Precipitation Hardening Ni-based Superalloys

   Author : Fabian Hanning; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; welding; post weld heat treatment; weldability; Nickel based superalloys; strain age cracking; weld cracking;

   Abstract : Manufacturing of hot structural components for aero engines requires the materials being used to be weldable. The high demands on strength and temperature resistance make nickel based superalloys the material of choice for this application. READ MORE

5. 3. Weld Cracking of Precipitation Hardening Ni-based Superalloys - Investigation of repair welding characteristics and susceptibility towards strain age cracking

   Author : Fabian Hanning; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gleeble; Haynes 282; Waspaloy; welding; ATI 718Plus®; weldability; post-weld heat treatment; weld cracking; strain age cracking; hot cracking; Nickel-based superalloys;

   Abstract : High temperature resistance and strength requirements make nickel-based superalloys the material of choice for the hot section of aero engines. Fabrication in terms of combining wrought and cast parts in the manufacturing of hot structural components enables component optimisation via the use of wrought high-strength parts, where geometrical constraints allow, and cast parts to produce complex geometries.

6. 4. Characterisation of terahertz integrated membrane circuits

   Author : Johanna Hanning; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waveguide width error; calibration; THz; membrane circuit; TRL; measurement uncertainty; single-flange 2-port; 220–325 GHz; cable flex; WR-03; VNA; S-parameter;

   Abstract : In this thesis a novel measurement setup and thru-reflect-line (TRL) calibration kit for vector network analyser (VNA) measurements at 220 GHz to 325 GHz (WR-03) is presented. Measurements on passive membrane circuit devices under test (DUTs) show improvement in the S-parameters compared to a waveguide integrated membrane circuit setup in previous work, especially in reducing the ripples and increasing repeatability of the measurements.

7. 5. Manganese Combined Oxides as Oxygen Carriers for Chemical-Looping Combustion

   Author : Malin Hanning; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon capture; combined oxide; manganese oxide; chemical-looping;

   Abstract : The global emissions of greenhouse gases are increasing and the development of mitigation measures is becoming more important. One of the alternatives proposed is carbon capture and storage, where the carbon dioxide emitted from large point sources is captured, compressed and stored in underground storage sites. READ MORE
