  2. 21. 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

  4. 22. Imperfections in Recycled Aluminium-Silicon Cast Alloys

    Author : Anton Bjurenstedt; Anders Jarfors; Salem Seifeddine; Pål Schmidt; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Imperfections; Recycled cast Al-Si alloy; Fe-rich particles; Melt quality; Fractography; Differential scanning calorimetry.;

    Abstract : In striving to produce high quality cast components from recycled aluminium alloys,imperfections have to be considered, because recycled aluminium usually containsmore of it. However, there are great energy savings to be made by using recycledaluminium; as little as 5% of the energy needed for primary aluminium productionmay be required. READ MORE

  5. 23. 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

  6. 24. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons

    Author : Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Flake graphite; Compacted graphite; Spheroidal graphite; Elastic deformation; Plastic deformation; Modulus of elasticity; Graphite modulus of elasticity; Strength coefficient; Strain hardening exponent; Acoustic emission; Construction materials; Konstruktionsmaterial;

    Abstract : The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. READ MORE

  7. 25. Optimized Development Process for Cast Components

    Author : Andreas Holmström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Development process; time discretization; thermo-metallurgical simulation; multi-disiplinary optimization;

    Abstract : In developing trucks, cast components of low weight andhigh durability need to be developed and produced. Cast componentsrepresent an estimated 10-15 percent of the total weight of atruck. There is a strong coupling between the production processand the mechanical properties of a cast component such as it'sstrength. READ MORE
