1. Tribological and Mechanical Behaviour of Lamellar and Compacted Graphite Irons in Engine Applications
Abstract : There has been much discussion about the beneficial uses of lamellar graphite iron in piston rings–cylinder liner systems, where a good combinations of both thermal and tribological properties are essential. The excellent tribological performance of lamellar iron under such sliding conditions is principally associated with lubrication behaviour of the graphite particles which are distributed as lamellas throughout the matrix.

2. Defect Formation during Solidification in Grey Iron Castings
Abstract : The presence of defects is of major concern in the production of grey iron castings. Some defects are merely an aesthetic problem while others can be detrimental for the performance of the component. Among the several possible defects, shrinkage porosity is one of the more challenging to understand and avoid. READ MORE

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

5. Microstructure and deformation behaviour of ductile iron under tensile loading
Abstract : The current thesis focuses on the deformation behaviour and strain distribution in the microstructure of ductile iron during tensile loading. Utilizing Digital Image Correlation (DIC) and in-situ tensile test under optical microscope, a method was developed to measure high resolution strain in microstructural constitutes. READ MORE
