  1. 1. Fatigue strength of engineering materials : the influence of environment and porosity

    Author : Jan Linder; Bengt Lindberg; Lennart Josefsson; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; cast aluminium; hardened steels; fatigue; corrosion; crack propagation; spot weld; porosity; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : The objective of this work was to use LEFM in order to assess the detrimental influence of surrounding chloride-containing environments for stainless steels, hardened steel as well as for a cast aluminium alloy. An additional aim was also to use LEFM to assess the influence of porosity on the fatigue properties for different commercial cast aluminium alloys and manufacturing methods. READ MORE

    Abstract : In mid-eighteenth century Paris, two Benedictine monks from the Congregation of Saint-Maur – also known as the Maurists – started compiling a universal dictionary of arts, crafts, and sciences. The project was initiated simultaneously with what would become one of the most famous literary enterprises in Western intellectual history: the Encyclopédie of Diderot and d’Alembert. READ MORE

  5. 5. The Atmospheric Corrosion of Magnesium Alloys : Influence of Microstructure and Environments
