Development. design and manufacturing of heavy truck engine parts require improved knowledge on solidification kinetics and development of material properties. A suitable tool to handle the complex shape and solidification kinetics is the computer simulation of the casting process. The result is dependent on the thermophysical properties used, boundcny condition and the quality of kinetic models implemented for calculation of resulting metallographical structure and material properties.
The paper will present an analysis of the microstructure obtained in the cylinder head casting. The thermal analysis and cooling curves have been obtained through thermocouple measurements in the cylinder head. The microstructure analysis concerns both solidification and solid-state transformation The microstructure is related to the obtained mechanical properties as hardness. The filling, solidification and mechanical properties of the cylinder head have been simulared and compared with the results obtained from measurements. The calculated and measured cooling curves are compared as well.
