  2. 1. Residual stresses, fatigue and deformation in cast iron

    Author : Mattias Lundberg; Johan Moverare; Ru Lin Peng; Taina Ahmad; Daniel Bäckström; Maqsood Ahmad; Sten Johansson; Mattias Calmunger; Peter Hedström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The complex geometry of cylinder heads in heavy-duty diesel engines makes grey iron or compact graphite iron a preferred material choice due to its price, castability, thermal conductivity and damping capacity. Today’s strict emission laws have increased the demands on engine performance and engine efficiency. READ MORE

  4. 2. Microstructure Formation and Mechanical Properties in Compacted Graphite Iron

    Author : Mathias König; Ingvar L. Svensson; Magnus Wessén; Torsten Sjögren; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; CGI; Microstructure formation; Mechanical properties;

    Abstract : Compacted graphite iron is rapidly becoming an attractive alternative for engine applications in the automotive industry. The improved process control now available that allows CGI components to be cast in a reproducible and reliable way has been the driving force for this development. READ MORE

  5. 3. Aspects of Crack Growth in Single-Crystal Nickel-Base Superalloys

    Author : Christian Busse; Daniel Leidermark; Kjell Simonsson; Johan Moverare; David Gustafsson; Björn Sjödin; Louis J. Ghosn; Linköpings universitet; []

    Abstract : The aim of this thesis is to study trust in military leaders. Empirical data was gathered through interviews and questionnaires with military personnel mostly from Sweden, but also from four other European countries. READ MORE

  7. 5. Geochemical and mineralogical laboratory methods in waste rock drainage quality prediction

    Author : Teemu Karlsson; Lena Alakangas; Päivi Kauppila; Andrew Barnes; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extractive waste characterisation; drainage water; ARD; NRD; ABA test; NAG test; SEM; Applied Geochemistry; Tillämpad geokemi;

    Abstract : Harmful substances containing acid or neutral rock drainages (ARD and NRD) are a major challenge related to the management of extractive industry wastes. This issue is particularly related to deposits containing sulphide minerals, which are prone to oxidization under the influence of atmospheric oxygen and water. READ MORE
