Original abstract
The structure of austempered ductile iron (ADI) matrix and consequently its mechanical properties are influenced by the geat treatment conditions, above all by the temperature and dwell length of isothermal transformation. The paper is focused on deeper understanding the interrelation between matrix mixture composition and static mechanical properties of ADI in dependence on the isothermal transformation dwell. Practical aim of the paper is to find the optimal isothermal transformation dwell range for ADI isothermally transformed at the temperature of 380oC with emphasis on the level of static mechanical propertios in tension. Microstructure and mechanical properties cahnges that procees during isothermal transformation are observed and evaluated for the transformation dwells of 2, 5, 10,25, 60, 120,270 and 540 minutes.
