  2. 1. Morphological characterization of primary austenite in cast iron

    Author : Juan Carlos Hernando; Attila Diószegi; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lamellar Graphite Iron; Solidification; Primary Austenite; Microstructure Evolution; Dendritic coarsening; Compacted Graphite Iron; Magnesium Fading; Nodularity;

    Abstract : Automotive industry products portfolio includes a wide variety of complex‐shaped cast iron products, such as truck engine components, that need to withstand a constant trend of higher demands, especially urged by stricter environmental regulations on emissions. Combined with this continued demand on properties improvement, cast iron industry faces a process problem related to the lack of understanding of solidification and mechanisms behind defect formation.

    Abstract : Automotive industry products portfolio includes a wide variety of complex-shaped cast iron products, such as truck engine components. Urged by strict environmental regulations on emissions, these components constantly need to combine higher demands on performance with lighter designs. READ MORE

  5. 3. Study of solidification and volume change in lamellar cast iron with respect to defect formation mechanisms

    Author : Péter Svidró; Pär Jönsson; Pål Schmidt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lamellar cast iron; shrinkage porosity; solidification; volumetric change; dendrite coherency; inter-dendritic space;

    Abstract : Lamellar cast iron is a very important technical alloy and the most used material in the casting production, and especially in the automotive industry which is the major consumer. Beside the many great properties, it is inclined to form casting defects of which some can be prevented, and some may be repaired subsequently. READ MORE

  7. 5. Thermal Conductivity of Cast Iron: Influences of Microstructure on the Thermal Conductivity of Cast Iron

    Author : Daniel Holmgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EBSD; Laser Flash Technique; Modelling; Spheroidal Graphite; Lamellar Graphite; Primary Austenite; Compacted Graphite; Pearlite; Ferrite; Thermal Conductivity;

    Abstract : The thermal transport properties of cast iron are important in high temperature applications,where the temperatures should be kept low and the thermal gradients within the componentsmall. Dimensional and microstructural changes, thermally induced stresses and even failuremight be catastrophic consequences of intense and/or unevenly distributed temperatures. READ MORE
