  4. 4. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    University dissertation from Institutionen för konstruktions- och produktionsteknik

    Author : Salem Seifeddine; Birger Karlsson; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik;

    Abstract : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. READ MORE

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

    University dissertation from Institutionen för konstruktions- och produktionsteknik

    Author : Dogan Ergun Oner; [2003]
    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
