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

    Författare :Mathias König; Ingvar L. Svensson; Magnus Wessén; Torsten Sjögren; Högskolan i Jönköping; []
    Nyckelord :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

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

    Författare :Mathias König; Jorge Sikora; Magnus Wessén; Ingvar L. Svensson; Chalmers University of Technology; []
    Nyckelord :Solidification; Solid state transformation; Modelling; Mechanical properties; Cast iron; CGI; Microstructure formation; Cast Iron; Microstructure Formation; Mechanical Properties; Solid State Transformation;

    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

  3. 3. Microstructure-based Mechanical Behaviour in Structural Analyses of Cast Components

    Författare :Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Torsten Sjögren; Högskolan i Jönköping; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; Structural analysis; Mechanical behaviour; Casting process simulation; Finite element method simulation;

    Sammanfattning : In the process of developing cast iron and cast aluminium components, the co-operation between product development and production is important. On the engineering level, this co-operation is limited already in the product development phase e.g. by the lack of established methods to consider the mechanical behaviour of the completed component.

  4. 4. Simulation of Microstructure-based Mechanical Behaviour of Cast Components

    Författare :Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Franco Bonollo; Högskolan i Jönköping; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Component behaviour; structural analysis; mechanical behaviour; casting process simulation; Finite Element Method FEM simulation;

    Sammanfattning : In the process of developing cast iron and cast aluminium components, a high level of co-operation between product development and production is of great importance. From an engineering standpoint, this co-operation is limited early in the product development phase by e.g. LÄS MER

  5. 5. On the Residual Stresses and Microstructure Formation of Aluminum-Silicon Cast Alloys

    Författare :Mohsen Sadrossadat; Sten Johansson; Ru Lin Peng; Ingvar L Svensson; Linköpings universitet; []
    Nyckelord :Al-Si alloys; residual stresses; microstructure; microsegregation; nucleation behavior; modeling; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Cast aluminum-silicon alloys are being increasingly used in automotive and aerospace industries for critical structure applications because of their excellent castability, low density, acceptable mechanical properties and low cost. Different casting and heat treatment parameters largely affect the microstructure and residual stress of the components, which in turn, has a great impact on their mechanical properties. LÄS MER
