Microstructure and tensile property simulation of grey cast iron components
2004 (English)Report (Other academic)
Designers and manufacturers of grey cast iron components have for a long time been interested in predicting microstructures and tensile properties. Accurate predictions are desirable to develop and optimize cast components as well as to reduce manufacturing expenses.
Recent developments in the field of eutectic nucleation, eutectic growth and prediction of tensile strength in grey cast iron have been implemented into commercial, finite difference method based, simulation software. Cylindrical samples with varied cooling conditions and a complex shaped cylinder head have been simulated. The simulation procedure includes kinetic models for microstructure prediction. A new fading law is introduced to calculate the nucleated eutectic and inoculants adapted eutectic growth. The tensile strength is calculated using a model based on the stress intensity in the metallic matrix caused by the presence of graphite flakes.
Cooling curves, microstructure and tensile properties obtained by simulation are compared to measured values.
