Determination of mechanical properties in CGI- cylinder blocks by experiment and simulation.

Sammanfattning: As the frontier of technology is pushed ever farther, the need for new and improved materials is always present. This thesis investigates the mechanical properties of compacted graphite iron (CGI) as it has been suggested as an alternative to traditional lamellar iron in truck cylinder blocks. The obtained values are compared to the mechanical properties predicted by a commercially available casting simulation software. This thesis shows that the mechanical properties vary within each CGI- cylinder block with respect to position and that the technology of casting several cylinder blocks with similar properties already exists. The casting simulation software used in this thesis was found to give conservative predictions of the evaluated mechanical properties.
