  1. 1. Compacted graphite iron On solidification phenomena related to shrinkage defects

    Detta är en avhandling från Jönköping : Jönköping University, School of Engineering

    Författare :Björn Domeij; Högskolan i Jönköping.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Spheroidal graphite iron; Solidification; Microsegregation; Porosity; Kompaktgrafitjärn; segjärn; stelning; mikrosegregation; porositet;

    Sammanfattning : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. LÄS MER

  2. 2. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

    Detta är en avhandling från Gothenburg : Chalmers University of Technology

    Författare :Mathias König; Högskolan i Jönköping.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast Iron; CGI; Microstructure Formation; Mechanical Properties; Modelling; Solidification; Solid State Transformation; Solid state transformation; Mechanical properties; Cast iron; Microstructure formation;

    Sammanfattning : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. LÄS MER

    Sammanfattning : The Swedish truck industry is forced to find new material solutions to achieve lighter engines with increased strength. Customers and new environmental regulations demand both higher specific power and more environmentally friendly trucks, and this places a rising pressure on the manufactures. LÄS MER

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

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :Mathias König; Högskolan i Jönköping.; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; CGI; Microstructure formation; Mechanical properties;

    Sammanfattning : 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. LÄS MER

  5. 5. On the solidification of compacted and spheroidal graphite irons

    Detta är en avhandling från Jönköping : Jönköping University, School of Engineering

    Författare :Björn Domeij; Högskolan i Jönköping.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compacted graphite iron; Spheroidal graphite iron; Solidification; Microsegregation; Kompaktgrafitjärn; segjärn; stelning; mikrosegregation;

    Sammanfattning : A good understanding of the solidification process of a cast material is essential to understand how the combination of alloy composition and the casting process variables combines into the solid cast component and its performance. The wrong combination may result in poor performance or casting defects. LÄS MER
