  5. 8. 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.

  6. 9. Thermal Cycling, Creep- and Tensile Testing of Cast Exhaust Materials at Elevated Temperatures

    Author : Christian Öberg; Stefan Jonsson; Henrik Östling; KTH; []
    Keywords : creep; constant-load; thermal cycling; tensile test; cast materials; cast iron; exhaust materials.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : An exhaust manifold of a truck engine is subjected to tough conditions. As the truck is started, operated and shut down, it becomes subjected to thermal cycling up to around 800°C. At such high temperatures, corrosion, fatigue and creep are active degradation mechanisms. READ MORE

  7. 10. Metal Expansion Penetration During Solidification of Grey Cast Iron

    Author : Izudin Dugic; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grey cast iron; solidification; solidification modelling; graphite expansion; molar volume; casting simulation; thennal analysis; thermoanalysis cup; casting temperature; inoculation; inoculant; meta! expansion penetration; eutectic cell size.; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The meta! expansion penetration has been examined experimentally. The whole casting process was simulated using a commercial software, in order to investigate the solidification characteristics and the pore formation in the casting studied. READ MORE
