  1. 1. Tribological and Mechanical Behaviour of Lamellar and Compacted Graphite Irons in Engine Applications

    Författare :Rohollah Ghasemi; Anders Professor; Lennart Assistance professor; Bengt-Göran Rosén; Anders Jarfors; Lennart Elmquist; Jönköping University; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sliding wear; abrasive wear; graphite lubricating performance; matrix deformation; lamellar graphite iron; high-Si compacted graphite iron;

    Sammanfattning : There has been much discussion about the beneficial uses of lamellar graphite iron in piston rings–cylinder liner systems, where a good combinations of both thermal and tribological properties are essential. The excellent tribological performance of lamellar iron under such sliding conditions is principally associated with lubrication behaviour of the graphite particles which are distributed as lamellas throughout the matrix.

  2. 2. Measurement and source apportionment of ubiquitous soot black carbon in sediments

    Författare :Marie Elmquist; Örjan Gustafsson; Per Andersson; Wulf Amelung; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; Miljökemi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : The pyrogenic particles formed from incomplete combustion of organic matter are often termed black carbon (BC) and they partake in many important biogeochemical processes. For instance, BC in water and sediment affects the solid-water partitioning of hydrophobic organic pollutants reducing their bioavailability. LÄS MER

  4. 4. Components, Safety Interfaces, and Compositional Analysis

    Författare :Jonas Elmquist; Simin Nadjm-Tehrani; Linköpings universitet; []
    Nyckelord :Component-based system development; safety-critical systems; safety interfaces; compositional analysis; modelbased development; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Component-based software development has emerged as a promising approach for developing complex software systems by composing smaller independently developed components into larger component assemblies. This approach offers means to increase software reuse, achieve higher flexibility and shorter time-to-market by the use of off-the-shelf components (COTS). LÄS MER

  5. 5. Defect Formation during Solidification in Grey Iron Castings

    Författare :Lennart Elmquist; Ingvar Svensson; Attila Diószegi; Doru Stefanescu; Jönköping University; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Shrinkage Porosity; Grey Iron; Solidification; Nucleation; Primary Austenite; DAAS; Eutectic Cells; Microstructure; Macrostructure; Hot Spot; Oxygen; Hydrogen; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The presence of defects is of major concern in the production of grey iron castings. Some defects are merely an aesthetic problem while others can be detrimental for the performance of the component. Among the several possible defects, shrinkage porosity is one of the more challenging to understand and avoid. LÄS MER
