  1. 1. The Functional Microstructure of Al/AlOx/Al Tunnel Junctions

    Author : Samira Mousavi Nik; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Grain Growth.; Interfaces; Microstructure; AlOx Tunnel Barriers; Transmission Electron Microscopy; Imaging; Spectroscopy; Superconducting Tunnel Junctions;

    Abstract : Josephson junction as a novel superconducting electronic component plays an important role in most small-scale superconducting systems. Particularly the Al/AlOx/Al tunnel junction, a high-performance junction made with a well-established microfabrication technology, is widely used as a building block of many quantum circuits.

  2. 2. High performing cast aluminium-silicon alloys

    University dissertation from Jönköping : Jönköping University, School of Engineering

    Author : Martin Riestra; Salem Seifeddine; Ehsan Ghassemali; Jessica Elfsberg; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium cast alloys; melt quality; eutectic modification; grain refinement; microstructure; tensile properties;

    Abstract : The need to produce lighter components due to environmental aspects and the development of electrical vehicles represents an opportunity for cast aluminium-silicon alloys. With high specific strength, good castability, high corrosion resistance and recyclability, these alloys offer an attractive combination of properties as an alternative to steel, cast iron and titanium-based components in certain applications.

  3. 3. On the microstructure and mechanical properties of Mg-Al alloys

    University dissertation from Jönköping : Jönköping

    Author : Haiping Cao; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mg-AI; microstructure; mechanical properties; divorced degree; modeling; mould constraint; segregation band; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The microstructural features and the mechanical properties of binary Mg-Al alloys have been investigated by using a gradient solidification technique. Homogeneous and nearly defect-free samples were produced under well controlled cooling conditions, through which the microstructural characteristics as well as the relationships between microstructure and mechanical properties in Mg-AI alloys were precisely defined.

  4. 4. On the Residual Stresses and Microstructure Formation of Aluminum-Silicon Cast Alloys

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Mohsen Sadrossadat; Sten Johansson; Ru Lin Peng; Ingvar L Svensson; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Al-Si alloys; residual stresses; microstructure; microsegregation; nucleation behavior; modeling; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Cast aluminum-silicon alloys are being increasingly used in automotive and aerospace industries for critical structure applications because of their excellent castability, low density, acceptable mechanical properties and low cost. Different casting and heat treatment parameters largely affect the microstructure and residual stress of the components, which in turn, has a great impact on their mechanical properties. READ MORE

  5. 5. Tool steel for tool holder applications microstructure and mechanical properties

    University dissertation from Karlstad : Karlstad University

    Author : Anna Medvedeva; Jens Bergström; Birger Karlsson; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steel; tool holder; microstructure; mechanical properties; machinability; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : Large improvements in cutting tool design and technology, including the application of advanced surface engineering treatments on the cemented carbide insert, have been achieved in the last decades to enhance tool performance. However, the problem of improving the tool body material is not adequately studied. READ MORE
