  2. 16. The influence of graphite morphology on the elastic behaviour of cast irons

    Author : Torsten Sjögren; Linköpings universitet; []
    Keywords : Cast iron; flake graphite; compacted graphite; spheroidal graphite; elastic behaviour; modulus of elasticity; graphite modulus of elasticity; nodularity; aspect ratio; plastic deformation; acoustic emission; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The morphology of the graphite phase largely controls the resulting properties of different grades of cast iron. In flake graphite cast irons, the mechanical properties are low while the thermal conductivity is high. In contrast, with spheroidal graphite cast irons, the mechanical properties are high while the thermal conductivity is low. READ MORE

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

    Author : Mathias König; Magnus Wessén; Ingvar L. Svensson; Jorge Sikora; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast Iron; CGI; Microstructure Formation; Mechanical Properties; Modelling; Solidification; Solid State Transformation;

    Abstract : 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. READ MORE

  6. 19. Factors Influencing the Formation of Shrinkage Porosity in Grey Cast Iron

    Author : Lennart Elmquist; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CET; Oxygen; Columnar zone; Grey iron; Shrinkage porosity; Equiaxed zone; Solidification; DAAS; Hydrogen; Primary austenite;

    Abstract : The presence of shrinkage defects is of major concern in the production of grey iron castings. This type of defect can penetrate through the casting as a three-dimensional network. READ MORE
