Original Abstract

Austempered ductile iron (ADI) belongs among structural materials with continuously increasing level of production. The study of interrelations among the conditions of isothermal transformation, resulting structure of ADI matrix and its static as well a fatigue behaviour was concentrated on the influence of the temperature of isothermal transformation, which was changed in the range from 380 to 500oC. Fatigue properties of obtained structeres were studied in detail determining S-N curves in highcycle region. Static tensile properties were compared with fatigue limits obtained by the fit of the whole S-N curves and with the content of retained austenite. Optimum fatigue properties were obtained for transformation temperature of 400oC when ADI matrix obtained the highest content of retained austenite.
