  2. 21. High-performance Load-bearing Alloys

    Author : Guo-Hua Zhao; Annika Borgenstam; Konstantinos Georgarakis; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The aim of this thesis is to study advanced metallic alloys as load-bearing componentsfor engineering and biomedical applications. The investigations have been focusing onthe improvement of the properties and performance of existing materials as well assynthesizing and developing completely new materials. READ MORE

  4. 22. Theoretical description of Ti and Ti alloys from first principles

    Author : Natalia Skripnyak; Igor Abrikosov; Iryna Yakimenko; Sergey Simak; Zi-Kui Liu; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; T; Ti alloys; DFT; molecular dynamics; thermodynamic properties; elastic properties;

    Abstract : Modern world is known for many advanced technologies and solutions to complex problems. Technical progress runs at high speed. In order to most effectively use materials, given to us by Nature, it is important to know their properties. To do laboratory experiments is often too expensive and time consuming. READ MORE

  5. 23. Theory of Disordered Magnets

    Author : Oleg E. Peil; Börje Johansson; Hubert Ebert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; disordered alloys; magnetic alloys; spin glasses; ab initio calculations; Monte Carlo methods; Physics; Fysik;

    Abstract : Studying magnetic properties of disordered alloys is important both for the understanding of phase transformations in alloys and from the point of view of fundamental issues of magnetism in solids. Disorder in a magnetic system can result in unconventional magnetic structures, such as spin glass, which have rather peculiar features. READ MORE

  6. 24. Uncovering Magnetic Order in Nanostructured Disordered Materials : A Study of Amorphous Magnetic Layered Structures

    Author : Panagiotis Korelis; Björgvin Hjörvarsson; Gabriella Andersson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous Materials; Magnetism; Amorphous Magnetism; Magnetic Measurements; Thin Films; Multilayers; Thin Film Deposition; Sputtering; FeZr Alloys; AlZr Alloys; X-ray Diffraction; Rutherford Backscattering Spectrometry; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : The scope of this thesis is the study of the interplay between structure and magnetism in amorphous materials. The investigations focus on the growth of amorphous layers and the study of the influence of structural disorder and reduced physical extension on the magnetic properties of thin films and multilayers.

  7. 25. Laser welding of aluminium alloys

    Author : Tomas Forsman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : This thesis treats laser welding of aluminium alloys from a practical perspective with elements of mathematical analysis. The theoretical work has in all cases been verified experimentally. The aluminium alloys studied are from the 5xxx and 6xxx groups which are common for example in the automotive industry. READ MORE
