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

2. Compacted graphite iron : On solidification phenomena related to shrinkage defects
Abstract : An improved understanding of solidification of compacted graphite iron (CGI) is necessary to predict shrinkage related casting defects. Spheroidal graphite is not only found in ductile iron (SGI) but usually also in CGI, but its characteristics and role in this material is less understood. READ MORE

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

4. On the solidification of compacted and spheroidal graphite irons
Abstract : A good understanding of the solidification process of a cast material is essential to understand how the combination of alloy composition and the casting process variables combines into the solid cast component and its performance. The wrong combination may result in poor performance or casting defects. READ MORE

5. Thermal Conductivity of Cast Iron: Influences of Microstructure on the Thermal Conductivity of Cast Iron
Abstract : The thermal transport properties of cast iron are important in high temperature applications,where the temperatures should be kept low and the thermal gradients within the componentsmall. Dimensional and microstructural changes, thermally induced stresses and even failuremight be catastrophic consequences of intense and/or unevenly distributed temperatures. READ MORE
