  2. 1. Describing Interstitials in Close-packed Lattices: First-principles Study

    Author : Noura Al-Zoubi; Levente Vitos; Se Kyun Kwon; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Describing interstitial atoms in intermetallics or simple mono-atomic close-packed metals is a straightforward procedure in common full-potential calculations. One establishes a sufficiently large supercell, introduces the interstitial impurity and performs the electronic structure and total energy calculation. READ MORE

  4. 2. Laboratory studies of forbidden decay processes in stored ions

    Author : Jonas Gurell; Sven Mannervik; Ahmed Al-Khalili; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic physics; Atomfysik; fysik; Physics;

    Abstract : Measurements of atomic and ionic data has been an active research area since the beginning of spectroscopic studies. The experimental data deduced from thesestudies are of great interest for our understanding of fundamental as well as applied physics. READ MORE

  5. 3. Initial Oxidation Kinetics of Al(111): A Monte Carlo Study

    Author : Dogan Ergun Oner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide nucleation and growth; dissociative adsorption; metal oxidation; Monte Carlo simulations; Al 111 ; kinetics; aluminium; surface oxidation;

    Abstract : Almost all metals around us have a thin oxide layer on top of the bulk metal underneath. Often this oxide film protects the metal against further oxidation, or corrosion. Examples are the oxide film that makes stainless steel "stain-less" or the ones on titanium and aluminium alloys, which are very corrosion resistant. READ MORE

  6. 4. Properties of Al-Mg Alloys and Vacancies in Al: a First-Principles Investigation

    Author : Karin M. Carling; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Phase transformations such as precipitation are used to control the strength of many technologically important aluminum alloys. In precipitation hardening, the material is heat treated and aged to produce precipitates, small particles of a different phase, in the matrix. READ MORE

  7. 5. Eutectic Modification of Al-Si casting alloys

    Author : Jenifer Barrirero; Frank Mücklich; Magnus Odén; Franz Jospeh Feikus; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Aluminum alloys with silicon as the major alloying element are the most widely used aluminum casting alloys. The eutectic phase in these alloys is formed by hard and brittle silicon plates in an aluminum matrix. Such silicon plates can act as crack propagation paths deteriorating the toughness of the material. READ MORE
