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

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

    Sammanfattning : 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. LÄS MER

  3. 2. Dendritic morphology and ultimate tensile strength of pearlitic lamellar graphite iron

    Författare :Vasilios Fourlakidis; Attila Diószegi; Carlos A. Silva Ribeiro; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lamellar graphite iron; Primary austenite dendrite; Ultimate tensile strength; Microstructure model;

    Sammanfattning : The continued development, of cylinder blocks and cylinder heads for heavy truck engines that are made of lamellar graphite iron (LGI) is focused on achieving high ultimate tensile strength (UTS) whilst conforming to environmental regulations. The purpose of this work is to further improve the tensile strength as well as the predictive engineering tools for optimization of LGI aimed to enhance the efforts for producing lighter and sustainable components without sacrificing performance.
